4096cb1830 Further work on libgme's emu2413. Fully remove floating point, introduce another precalculated table, directly use predefined tables instead of copying them. Reduces memory and codesize by several KB.

c97c5e5d17 Bugfixes for libgme by Mauricio Garrido: added missing call of Blip_set_modified(), correctly set PSG voices in vgm_emu, correctly set current_track in vgm_emu, correct call of Sound_mute_voices() in nsf_emu. Additionally migrate few floating point code to fixed point -- even though this is unused and therefor commented out.

7ad2cad173 Commit work started in FS#12153 to put timing/position information in PCM 
buffer chunks.

* Samples and position indication is closely associated with audio data
  instead of compensating by a latency constant. Alleviates problems with
  using the elapsed as a track indicator where it could be off by several
  steps.

* Timing is accurate throughout track even if resampling for pitch shift,
  whereas before it updated during transition latency at the normal 1:1 rate.

* Simpler PCM buffer with a constant chunk size, no linked lists.

In converting crossfade, a minor change was made to not change the WPS until
the fade-in of the incoming track, whereas before it would change upon the
start of the fade-out of the outgoing track possibly having the WPS change
with far too much lead time.

Codec changes are to set elapsed times *before* writing next PCM frame because
 time and position data last set are saved in the next committed PCM chunk.

e3b3547e20 Fix an issue in libfaad found by static code analysis. Two arrays within the drc_info structure require a size of 64 due to the related implementation. This code section would not have been called as the decoder checks the number of channels and rejects decoding for files using more than MAX_CHANNELS (2). Closes FS#12245.

b086458e4e FS#12231 
Centralize the selection of codec compilation flags to codec.make
to avoid having to duplicate the per cpu selection logic and the
build rule in the individual codec lib make files and make tweaking
easier.

The two special cases, libmad and libspeex were left alone.

I plan to introduce a var for arm generation so that appropriate flags
can be selected per generation as benchmarking results have shown that
different arm arches might have different optimal flags.

Adds support for several new game music formats (AY, GBS, HES, KSS, SGC, VGM and VGZ) and replaces the current NSF and NSFE with a new implementation based on a port of the Game Music Emu library 'GME'. This first submit does not cover the full functionality provided by the author's original patch: Coleco-SGV is not supported, some GME-specific m3u-support has been removed and IRAM is not used yet. Further changes are very likely to follow this submit. Thanks to Mauricio Garrido.
