c9183bf15e Commit FS#10422 by Yoshihisa Uchida. Seperates WAV and AIFF parsing from PCM decoding by introducing libpcm, a library for decoding linear and non-uniform PCM independently of the container format.

2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

9b9e22731c SWCODEC: Fix the problem of replaygain not being applied unless the menu is entered. Make all codecs set the replay gain or else formats that do not have replaygain will not set the gain back to default if a file with gain applied proceeded them.

97f369a587 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.

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.

80da8b141c FS#6357, patch 1: let iramcopy and bss share the same space in codecs and 
plugins. Currently, in case of plugins using IRAM bss is cleared twice,
once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only
during codec initialization. Also, removed double variables in codecs
storing a pointer to codec_api.

bbef13eddf SWCODEC: Stop clicks between tracks when resampler is active by only switching the DSP frequency and not resetting the resampler at track boundaries. Will make sure DSP is correctly flushed at dicontinuities but don't hear any problems currently.

cee9d3b47b Fixed header parsing in AIFF. The minimum header size is 54 bytes for an audio file. SSND chunk block_size and offset are 32-bit values, not 16-bit; this bug would probably never even matter since most sound data isn't block aligned.

354770088e Re-enable the currently unused and broken dithering and noise shaping code already in Rockbox, and make it a user option instead of a codec-controlled option. The majority of people probably will not even hear any difference with this enabled, but feedback is welcome. Save your settings!

ebadcc633a Put new_track on the codec_api, and use it instead of the reload_codec variable in most places. Should help with problems people have had with GUI vs. playback sync.

d8eaefe29a Code policed. Converted to generate internal s3.28 format directly (next 
task is removing use of interleaved audio). Fixed broken handling of 8
bit files.
