d4249affc4 Remove residual floating point code from libgme's ym2612_emu. Saves several KB of codesize.

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.

0aa2fcb3b6 Optimized compiler settings for libgme. ARM now uses -O1 except for the 2413 emulator. The speed on PP5022 increases by 0-5% (NSF, YM2413-VGM), 5-10% (GBS, VGM) and 10-15% (SGC, KSS, AY).

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.

acb0917556 Submit initial patch from FS#12176. 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.
