b9dba4f128 Sorry, switching back again to the "better behaved" ADX codec of r15494. 
Not perfect, but with a safer failure than the hacky old/reborn one.

1df1e7b0c7 Remove unused conf_preseek from buffering.c and all of its accountraments. This is _not_ a setting. This is a guessing tool used by either playback or buffering to serve its clients better. Use the REBUFFER_GUESS size in resume to help obviate pondlife's bug. This will also need to be used when FS8092 gets fixed correctly with a complete rebuffer for backward movements. It may also belong in buffering not playback, haven't decided for sure

8431c08b7d QMF filter memory doesn't need to be 32 bits, so convert it to 16 bits. Alter assembler code to reflect this. Also do a small optimization in the reverse block copy of the qmf_synth() Coldfire assembler.

35f23267bf Further optimised the filter vector math assembly for coldfire, and added assembly filter vector math for ARM. Both make use of the fact that the first argument of the vector functions is longword aligned. * The ARM version is tailored for ARM7TDMI, and would slow down arm9 or higher. Introduced a new CPU_ macro for ARM7TDMI. Speedup for coldfire: -c3000 104%->109%, -c4000 43%->46%, -c5000 1.7%->2.0%. Speedup for PP502x: -c2000 66%->75%, -c3000 37%->48%, -c4000 11%->18%, -c5000 2.5%->3.7%

3ea3caf341 * Flip argument order for scalarproduct() so that the first argument is always 32 bit aligned, like it is already the case for vector_add() and vector_sub(), for upcoming optimisations. * Un-inline the apply_filter functions for better cache utilisation.

86a999c478 Change decoder struct dynamic array members to static arrays sized based on current maximums. Move decoder state structs into IRAM for big speedups This means only one decoder can be instantiated at a time, but that should not be a problem. Tweak Makefile to use -O2 for Coldfire.
