Fix libpng bug introduced by my previous pull request + misc fixes

Note: This commit does require the user to save settings to global or per-game configuration before switching ROMs. This is a small price to pay to have working per-game settings.

The bug was due to the last value of the Stereo option not being preserved before re-entering the menu. Thus, the audio was reinitialised anew both in SDL and the Snes9x core, erasing all notes and echoes, when the menu was exited.

This is counter-intuitive, but in tiles that are not fully transparent, it is more likely that a pixel is opaque. The change in this commit also eliminates one immediately-needed memory load per 4 pixels.

Computing the necessary values in TILE_CLIP_PREAMBLE cuts down on the cycles needed versus a load from memory that is unlikely to be cached at the time of every access.

…er functions around.

Based on libretro/snes9x2010@e9c304a by TwinAphex51224; some additional code modifications are removed.

* FxEmulate now uses fx_run directly.
* Pointers to function pointers that were formerly selected according to whether Super FX breakpoints are enabled are replaced with references to the actual array. This allows the linker to insert constant addresses.
* Super FX breakpoints are now unsupported.

…t to execute.

The uses of global variables 'GSU.vCounter' and 'GSU.vInstCount' are deleted with this commit. Local variables can be kept in registers and, in that case, there are no stores to memory before each opcode function is executed.

This commit is based on dmitrysmagin/snes9x4d-rzx50@c1b5ea1 but includes only the code relevant to S-DD1 decompression chip emulation.

Also fix a bug causing "Ported to OpenDingux by pcercuei" not to appear in the credits.

On the GCW Zero, the Home key is input by quickly pressing and releasing the Power slider upwards.

Unsetting the Transparency option prevents most SNES games from rendering anything ever. The option file format does not change, but the word for this option is now disused and the Transparency option is always enabled.

* Require Menu Select and Menu Cancel to be released before exiting most menus.
* Prioritise Menu Select and Menu Cancel over the rest so that a direction does not apply if one of those is held.

This is a giant hack. It reorganises lots of code and copy-pastes the fix multiple times.

* SAL_SCREEN_ROTATED is removed.
* SAL_SCREEN_X_STRIDE_* and SAL_SCREEN_Y_STRIDE_* are removed.
* The pitch of a surface is gotten using sal_VideoGetPitch() instead of being a #define.

* The timing spin-loop using sal_TimerRead() in main.cpp:Run is now a sleeping loop in main.cpp:S9xSyncSpeed, reducing CPU usage (increasing battery life) and more closely matching the refresh rate of the LCD for 60 Hz games.
* The audio is kept active but muted if Sound is set to OFF, because otherwise the emulation would not advance due to the above.
* The audio is not muted via S9xSetSoundMute anymore, because that is automatically undone if SNES Global Mute is enabled, then disabled.

Minor changes:
* 3 frames worth of audio are buffered instead of 2. Frames are now skipped if the number of frames worth of buffered audio falls below 2, except if using manual frameskip.
* Volatile variables are read less often in sal_sound.c.

This commit also fixes the following issues:
* The timing is off from a real SNES by 3%~5%.
* Sound may overrun multiple times per second, leading to a data race that causes SNES notes to lengthen, to shorten or to be deleted.
