new options is appreciated. Thanks to Dan Everton for the settings/GUI
code.

cc94ae45a7 Keep assembler versions of DSP routines in dsp_arch.S files. This also 
solves the annoying register allocator problem when not using
-fomit-frame-pointer for the Coldfire assembler optimised crossfeed
routine.

ea4ccb5aba Samples should always be 32 bit on all platforms, so change most 
occurences of long to int32_t to enable working sounds also on 64 bit
sims. Note that some codecs (MP3 and Wavpack) still have other 64
bit related problems.

6472ecfc2e Added a couple inline assembly functions for ARM targets. This just about 
doubles the speed of crossfeed and makes a more modest improvement to the
replaygain loop.

more unpleasant surprises!

413da2a3d9 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.

abd9f83e92 Two new sections for IRAM usage: .irodata (selectable with the ICONST_ATTR attribute macro), allowing to put 'const' data into IRAM without causing a section type conflict, and .ibss (selectable with the IBSS_ATTR attribute macro) for uninitialised data. * Rockbox core: Adjusted the linker scripts and init code to not include the .ibss section in the binary, it is cleared instead. Saves ~500 bytes on archos and ~30KB on iriver. Codecs and plugins don't handle .ibss in a special way yet. * The init code properly handles empty sections now (except .stack, which should never be empty). * Unified the init code for SH1 and coldfire a bit.
