d3ecbbf988 Turnaround time must be included in dsp yielding to throttle against other threads. Do at least one per buffer full as well (or things can stick a bit on initial input triggers).

fd052ec753 Commit FS#8750. Add ARM assembler for the dsp-functions channels_process_sound_chan_mono(), channels_process_sound_chan_karaoke(), sample_output_mono() and sample_output_stereo(). By measurement the speed up is ~75% for the first three functions and ~40% for sample_output_stereo(). Additionally avoid calling yield() to often in dsp.c -- it is now limited to once per tick.

39e2de8f1b Crossfeed settings used to be stored inverted in the cfg file for legacy reasons, change that and kill some identical formatting functions while we're at it. NOTE TO CROSSFEED USERS: this will completely garble your crossfeed settings, write them down if you want to keep them.

369c2a37b7 SWCODEC & Coldfire: Do some more DSP straigntening out. Do as much Coldfire optimizing as seems reasonably possible by jumping through some hoops to avoid stalls. Further boost reduction will just be fractional points if taken to extremes-- not worth it. Wrap up the ASM for awhile.

a7fabf0741 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.

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.

aba6ca0881 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.

5f48e1590f 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. 
Tested quite thorougly, but as always, be careful with your ears.
