+ Cleanup

… into dietpi-services_v2

+ DietPi-Software | Airsonic/Subsonic: Currently incompatible with Buster due to Java 8 dependency

+ DietPi-Update | Do not allow insecure connections when downloading update archive, instead show progress bar (instead of default meter) for such a small download, similar to wget output.
+ DietPi-Update | Prefer curl, do not show progress for tiny downloads but always print errors

+ DietPi-Cleaner | Fix "i" index shared throughout nested functions (Run_Cleaners => Run_Cleaner_2). To be failsafe, localise every loop index in functions once, as general coding style.

+ DietPi-Globals | G_OBTAIN_CPU_TEMP(): Add support for Core2Duo CPUs and make $print_full_info input failsafe.

+ CHANGELOG | v6.25 DietPi-Cleaner fix and Core2Due CPU temp support

+ DietPi-Login | Exit sourced login script only but not the login shell: exit > return

+ CHANGELOG | DietPi-Login: Resolved an issue where login leads to immediate logout if DietPi scripts were not loaded to DietPi-RAMdisk location

DietPi-Services 2.0

+ CHANGELOG | Re-add v6.24.1 PR link

+ DietPi-Patch | Remove dietpi-process_tool files from disk location as well

+ DietPi-Globals | Remove exiting in case of unset or unknown $TERM:

- This will exit the whole shell, so "return" would be required instead to only exit the sourced script.
- The issues this was initially added for, do not apply any more: #1703
  - ~/.bashrc is called on all "interactive" shells, which includes sftp, scp and rsync
  - Only bash -c '/path/to/script' and e.g. systemd and cron are excluded.
  - But sftp, scp and rsync all fail the following checks: [[ -t 0 ]], [[ $PS1 ]] and [[ $- == *i* ]]
  - This means that /etc/bash.bashrc returns due to it's [[ -z $PS1 ]] check, thus /etc/bashrc.d/dietpi.bash is never called.
  - But we will add all three above checks to /etc/bashrc.d/dietpi.bash to assure nothing loads when anything breaks interactive use of the shell. DietPi-Globals itself can and should load regardless
  - Side note: All three sftp, scp and rsync pass $TERM=dumb already.

+ DietPi-Login | Failsafe: Assure the shell is interactive by all means [[ -t 0 && $PS1 && $- == *i* ]], else skip loading DietPi login scripts.

+ DietPi-Services 2.0 | Fine tuning part one
+ DietPi-Globals | Skip pre-generating some rarely used variables, which are now instead checked via: [[ $var ]]
+ DietPi-Globals | But pre-generate G_PROGRAM_NAME within G_INIT() since this is expected for script internal outputs. Use originating command in case it was not set by originating script
+ DietPi-Drive_Manager | Unset G_DIETPI_SERVICES_DISABLE instead of exporting it with default. It is now checked via [[ $G_DIETPI_SERVICES_DISABLE ]] in scripts.

+ DietPi-Services | Create systemd wrappers and drop-in configs inside /etc/systemd/system/ always, leave /lib/systemd/system/ for APT package installs only
+ DietPi-Services | Do not check /usr/lib/systemd/system/ for service files, since this is never used by systemd: https://manpages.debian.org/stretch/systemd/systemd.unit.5.en.html
+ DietPi-Services | Populate_Available_Array() only once each script execution, which renders $INIT_ALL_ARRAYS obsolete. In case values are changed from menu, re-estimate them per-service. This solves the issue that aSERVICE_RESTART_REQUIRED[] is overwritten for all services, e.g. when one gets reset.
+ DietPi-Services | Instead of looping through all known services and checking aSERVICE_AVAILABLE[], unset aSERVICE_NAME[] for all non-existent and excluded services. This reduces array memory size and loop counts vastly.
+ DietPi-Services | Pass aSERVICE_NAME[] always in double quotes as command argument, to be failsafe if service name contains spaces or magic characters
+ DietPi-Services | Merge single + all service modes, by adding single input service to the arrays only and skip Init_Array() then
+ DietPi-Services | Only print banner when running with input mode, otherwise the menu prompt should be info enough.
+ DietPi-Services | Align command usage output with Linux standards
+ DietPi-Services | Reorder: Separate "Service Control" and "Process Tool" functions
+ DietPi-Services | Correct I/O priority default
+ DietPi-Services | Further coding simplification and enhancements: E.g. process tool arrays are only loaded in menu mode to further speed up regular input modes.

+ DietPi-Software | Deluge: Lowered UMask to allow read access from e.g. custom Samba shares without "dietpi" user

+ CHANGELOG | Deluge: Lowered UMask (007 => 002) to allow read access from e.g. custom Samba shares without "dietpi" user

+ DietPi-Services | Service control: Fix masked service handling: Detection via [[ -e ]] required. Skip when applying service states, besides with unmask or status command. Hide process tool settings if masked.
+ DietPi-Services | Process tool: Merge saving and resetting process tool into one function. Allow to apply single settings or all saved ones. Do not apply default values to config file if not explicitly set by user. Allow to reset individual values to system defaults.
+ DietPi-Services | Edit: Do not allow to edit service file directly, instead create a drop-in config with commented original file content. Allows user to un-comment and edit single required lines, while having overview over remaining file and allows easy reverting by commenting/removing changed lines or the whole drop-in file.
+ DietPi-Services | Fix masked service path identification; Service will be skipped if only the /dev/null symlink exists but no actual service file.
+ DietPi-Services | Show also excluded services in menu and allow to add/exclude/include services.
+ DietPi-Services | Show/hide/reset process tool settings and set defaults correctly, based on chosen scheduling policy/class.
+ DietPi-Services | Code reorder: Sort menu handlers in same order as entries
+ DietPi-Services | Allow to cancel service edit before creating new drop-in
+ DietPi-Services | Re-apply "mariadb" => "mysql" service name fix for Jessie
+ DietPi-Services | Disable (dietpi_controlled) services before masking, otherwise, if enabled, a useless symlink will stay in place and systemd will prompt a warning on boot
+ DietPi-Services | Print info, if services are skipped due to mask state

+ DietPi-Software | FFmpeg: On RPi, install new package from archive.respberrypi.org APT repo, which includes hardware acceleration and is some subversions newer then our own compiled package (on Buster even 4.X).

+ DietPi-Patch | Syntax

+ DietPi-Globals | G_AGP: Simplify generation of installed package list. "dpkg --get-selections" takes input and handles wildcards exactly the same way as APT, so it can do the job for us. ":<arch>" suffixes are correctly handled by APT as well.

+ DietPi-Software | Simplify G_AGP wildcard input, which is handled correctly function internally

+ DietPi-Software | Gitea: Install latest stable v1.8.X

+ DietPi-Patch | Reinstall Gitea to update to v1.8.X

+ CHANGELOG | Gitea: Current stable v1.8.X will be installed now and existing installs will be upgraded during DietPi-Update

+ DietPi-Patch | Aliases not available in scripts

+ DietPi-Globals | G_BACKUP_FP(): Minor coding

+ DietPi-Services | systemd DOES read units from /usr/lib/systemd/system/

+ DietPi-Software | ympd: Use official non-capital letters naming
+ DietPi-Software | ympd/myMPD: On uninstall, unmask and disable service to remove all possible traces
+ DietPi-Software | myMPD: Do not apply wrong "group" setting
+ DietPi-Software | myMPD: Add libmediainfo to dependencies to support internal album covers
+ DietPi-Software | myMPD: Install latest master release, which works well now
+ DietPi-Software | myMPD: Revert to systemd unit provided by installer, apply "dietpi" group via drop-in config
+ DietPi-Software | myMPD: Skip "mympd" user creation as this is done by installer, but add it to "dietpi" group
+ DietPi-Software | myMPD: Failsafe config adjustment and do not touch on reinstall
+ DietPi-Patch | myMPD: Update to current master, reset of config file required

+ DietPi-FirstBoot | Move all first boot setup steps into a separate script and systemd unit
+ DietPi-FirstBoot | Fix RPi3 A+ default clocks
+ DietPi-Boot | Failsafe network interface and swap file value estimation

+ DietPi-Software | O!MPD: Set "server.stream-response-body = 1" with Lighttpd to resolve database update loop
+ DietPi-Software | O!MPD: Install current version from master branch, which fixes a bug with Buster Lighttpd on "Now Playing" page as well. After next official release, revert to latest release from: https://api.github.com/repos/ArturSierzant/OMPD/releases/latest
+ DietPi-Software | O!MPD: Install dependencies for YouTube and Tidal support. Python is installed with MPD anyway so it is minimal overhead for users that do not require it.
+ DietPi-Software | O!MPD: Preserve old config file and database completely, old database will be migrated automatically
+ DietPi-Software | O!MPD: Use local override config instead of touching the default config file
+ DietPi-Software | O!MPD: Do not manually create and import the database, as this is done automatically, if database user exists
+ DietPi-Software | O!MPD: Switch to mysqld socket connection which is generally to be preferred when database server and webserver/PHP are on the same machine
+ DietPi-Software | Minor coding
+ DietPi-Update | Safe new Git owner+branch to file BEFORE running incremental patches to assure that all GitHub downloads are done/attempted from matching branch, e.g. during software reinstalls
+ DietPi-Update | Minor coding
+ DietPi-Set_software | Verify_DietPi_Txt(): Current $G_GITBRANCH/$G_GITOWNER can be used, since DietPi-Update now saves these values before calling this script.
+ DietPi-Set_software | Minor coding

+ DietPi-Globals | G_DIETPI-NOTIFY(): Fix incorrect cursor movement after animation print:
- In case of colour codes
- If tput cannot estimate screen width due to STDOUT + STDERR redirection: dietpi-update. We export $G_WHIP_SIZE_X_OVERRIDE there to have correct values available for G_WHIP_*, so we can use it here as well.

+ DietPi-Software | UrBackup Server: Grab latest version from base URL

+ DietPi-Services | UrBackup: Use tmp dir in dietpi_userdata to allow reduced SD writes when userdata has been moved to external drive
+ DietPi-Services | UrBackup: Remove really all related files/dirs on uninstall

+ CHANGELOG | MotionEye: Resolved an issue on ARMv6 where install failed

+ DietPi-Software | PHP: On ARMv6 add libcurl4-openssl-dev to be pulled from Buster repo, as Stretch version depends on libcurl3 which conflicts libcurl4 from Buster. This resolves a failing MotionEye install.

+ DietPi-Drive_Manager | Fix aDRIVE_ISPARTITIONTABLE detection to not offer formatting in partition mode if file system is directly written to drive without partition table
+ DietPi-Drive_Manager | Do not stop services on script start, but instead before selected tasks
+ DietPi-Drive_Manager | Do not re-init drive arrays before and after every drive menu load, but instead after selected tasks
+ DietPi-Drive_Manager | Several coding enhancements

+ DietPi-Drive_Manager | Fix MENU_DRIVE_TARGET/MENU_DRIVE_INDEX handling

+ DietPi-Drive_Manager | Syntax

+ DietPi-Drive_Manager | Fix aDRIVE_ISPARTITIONTABLE estimation

+ DietPi-Drive_Manager | Samba mount point fix + further fine tuning

+ DietPi-Drive_Manager | Coffee required

+ DietPi-Drive_Manager | Localise "i" in functions to avoid double use

+ DietPi-Drive_Manager | Fix Samba mount version 3.1 must be 3.1.1 and is supported with Buster cifs-utils only

+ DietPi-Software | Nginx/Apache: Install CertBot modules when CertBot was installed before (ID 92) instead of Pi-hole (ID 93)

+ DietPi-Images | Minor coding, e.g. use G_DIETPI-NOTIFY if we already load DietPi-Globals and use "cmd || exit" instead of "! cmd && exit"

+ DietPi-Drive_Manager | I/O Scheduling: Add option to change I/O scheduler for single drives
+ DietPi-Drive_Manager | Fix missing partition table choice when manually selecting drive format mode, introduced with: 9ea3500
+ DietPi-Drive_Manager | Abort swapfile transfer on BTRFS with user info already here, before starting DietPi-Set_swapfile
+ DietPi-Drive_Manager | Minor coding and visual enhancements

+ DietPi-Software | Ampache: Apply chosen global software password for database to downloaded config file
+ DietPi-Software | Ampache: Preserve existing config files and database on reinstall

+ DietPi-Software | Medusa: Do not run in daemon mode, otherwise systemd with Type=simple will show its status as exited/dead

+ DietPi-NordVPN | Tiny

+ DietPi-Start_Kodi | Minor coding

+ DietPi-Set_software | Add function to disable APT cache, clean or move cache, lists and package downloads to RAM
+ DietPi-Config | Add menu to manage APT cache/lists/archives storage
+ DietPi-Patch | Disable APT cache by default and inform user
+ DietPi-PREP | Use new DietPi-Set_software function to disable and clear APT cache

+ DietPi-Set_software | Do not use G_CONFIG_INJECT to comment settings as this currently creates misleading output, e.g.: "Comment turned into setting: #..." and adds the commented setting even if it did not exist.
+ DietPi-Software | VNC Server: Only apply config if currently marked for install
+ DietPi-Software | Apply GPU settings only if related software is currently marked for install. Call function before apply installs marks 1 > 2

+ DietPi-Software | Medusa: Install FFmpeg and mediainfo used to show and probe media info. If missing, warnings are created in log.
+ DietPi-Software | Medusa: Install and use Python3 on Stretch+, as this is supported and recommended since some versions ago.
+ DietPi-Software | Skip one obsolete DietPi-Services stop call
+ DietPi-Software | Minor coding

+ DietPi-Software | FFmpeg: Remove FFmpeg dependency, which is not required if mediainfo is installed: pymedusa/Medusa#6829

+ CHANGELOG | Medusa: Remove FFmpeg dependency, which is not required if mediainfo is installed: pymedusa/Medusa#6829

+ DietPi-Set_userdata | Minor

+ DietPi-Drive_Manager | Only apply new userdata dir if "dietpi-set_userdata" actually succeeded
+ DietPi-Drive_Manager | Minor coding: Simplify spin-down timeout array generation and output

+ DietPi-Drive_Manager | Typo

+ DietPi-Drive_Manager | Fix "ecryptfs" detection which fails due to "eNcryptfs" pattern being scraped

+ CHANGELOG | DietPi-Drive_Manager: Resolved an issue where eCryptfs fstab entries were not detected and preserved correctly

+ DietPi-Drive_Manager | BTRFS support is not natively built into the kernel on RPi and Odroid: #2909

+ CHANGELOG | DietPi-Drive_Manager | Transferring RootFS to BTRFS is now denied

+ DietPi-Set_software | APT mirror: "buster-backports" does now exist, so add it by default
+ DietPi-Set_software | Add user: Apply encrypted global software password, if existent
+ DietPi-Set_software | Failsafe, wording and coding enhancements

+ DietPi-Software | Node-RED: Enable sudo permissions by default
