Remove FRACMUL_8_LOOP macro. This only benefited Coldfire, and we have assembler routines for the gain function there now.

Remove ACC_INIT, ACC and GET_ACC macros. These were quite Coldfire-centric macros which really aren't needed since all performance sensitive target DSP code should be assembler anyway.

Remove unused conf_preseek from buffering.c and all of its accountraments. This is _not_ a setting. This is a guessing tool used by either playback or buffering to serve its clients better. Use the REBUFFER_GUESS size in resume to help obviate pondlife's bug. This will also need to be used when FS8092 gets fixed correctly with a complete rebuffer for backward movements. It may also belong in buffering not playback, haven't decided for sure

Use the new DSP callback functionality in firmware/sound.c to deal with SWCODEC stereo width and channel configuration instead of the old more spread out #ifdef based approach. Rename the DSP functions involved for more consistent naming.

Add software based bass/treble controls for targets which have no such functionality in hardware (currently only X5). They can also be used on any other SWCODEC target by adding #define HAVE_SW_TONE_CONTROLS in the relevant config-*.h file. Also remove some now unneeded zero checks when using get_replaygain_int(). Comments on sound quality are welcome as some parameters can still be fine-tuned.

SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update.

96e5e9eef8
Optimise/touchup some asm macros in dsp.h, and also remove some now unneeded ones. Add config.h to dsp.c so that these macros actually get used, and also do some minor nitpicks to the resampler while I'm at it.

SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile.

Fix resampling clicking as much as possible at the moment. 1) Upsampling clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output.

Optimise EQ coef calculation routines for both speed and size. Move now unneeded fsqrt function to plugin fixed point library in case it'll be needed. Move all fixed point helper macros to dsp.h. Added FRACMUL_SHL macro to facilitate high-precision shifting of 64 bit multiplies and remove rounding from macsr in main thread to make this work as intended.

Rework PCM buffer
...
* Linked list instead of static array buffer pointers
* Variable sized chunks
* Improved mix handling
* Reduction in duplicated code
* Reduced IRAM usage w/o sacrificing performance
* Converted to almost entirely unsigned math
* Add pause function to reduce pcm_* exposure to playback.
This WILL break playback on the iPod until linuxstb makes a followup commit.
