Refactor repo structure

[zhangh43]

Task Description

This task aims to reorganize the repo topology, rename binaries/configs, and consolidate scripts into a consistent layout aligned with EloqData’s product structure.

🗂️ 1. Directory Structure
Verify and remove libservices/libmariadb/libmysqld, they seems to be embedded service, unnecessary to Eloqsql.

Remove unused directories: BUILD/Docs/debians/vio/win etc.

Remove unused files: KNOWN_BUGS.txt/INSTALL-WIN-SOURCE/CREDITS etc.

Move my-config.cnf → scripts/ and rename to eloqsql.cnf

rename mono_basic and mono_main test suite to

⚙️ 2. Binary and Config Renaming
Rename mysqld to eloqsql, my-config.cnf to eloqsql.conf, mysql_install_db to eloqsql_install_db, mysqld_safe to eloqsql_safe, mysql to eloqsql-cli

🧪 3. Testing & Validation

Verify configuration file parsing and startup with eloqsql.conf.

Update Concourse pipelines (regression ci and release ci) for the new build and binary names.

• Remove unsed files: KNOWN_BUGS.txt/INSTALL-WIN-SOURCE/CREDITS/appveyor.yml/.gitlab-ci.yml
• Move my-config.cnf → scripts/ and rename to eloqsql.cnf

( If remove libservices/libmariadb/libmysqld, failed to compile because other moudules depend them.

• libmariadb is mariadb-connector-c.
• libservices is the key components of MySQL's modular architecture and provide the function interface of sharing between plug-ins.
• libmysqld is embedded lib but it used by "extra/mariabackup". )

new symbol link for eloqsql (

• eloqsql -> mariadbd
• eloqsql-cli -> mariadb
• eloqsql-safe -> mariadbd-safe
• eloqsql-safe-helper -> mariadbd-safe-helper
• eloqsql-install-db -> mariadb-install-db )

rename test suite

• Rename mysql-test/mono_basic -> mysql-test/eloq_basic
• Rename mysql-test/mono_main -> mysql-test/eloq_main
