Commit first part of FS#11235 by Buschel and I. Improves scheduling on arm9 for two filter macros in libmad that are almost never called. A larger speed up will be possible when the remaining ASM code is improved.

Clean up libmad, remove unused compile options and source paths.

Tiny refactoring of libmad's synthesis filter. This allows minor speed up and higher precision on ARM, plus a simplification in dct32 configuration.

libmad: small tweak to coldfire inline asm, gives a slight speedup and now builds fine with gcc 4.4.4

Submit FS#11491. Refactor coldfire inline asm within libmad's synth_full() to gain better readability. Thanks to Nils Wallménius for supporting.

Comment unused code in libmad. Clean up initialization and memset'ing of decoder arrays.

Refacture libmad's synthesis filter via macro usage. Comment unused special synthesis filter for half bandwidth.
