8cfbd3604f Use cookies for thread identification instead of pointers directly which gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required.

a29b659758 Assembler optimised mono predictor for ARM. Speedup for -c1000 mono is ~5% on PP, ~8% on Gigabeat S (less for higher compression levels). Also fix some overlooked comments in the stereo predictor.

c1cd0469ca Implement mono predictor in assembler for coldfire, yielding a ~6% speedup for mono -c1000. Apply ideas gained from it back to the stereo predictor, saving 4 instructions. No speed increase for stereo, probably due to cache aliasing effects. * 80-column police.

113c285045 On ARM9TDMI (e.g. Gigabeat F) it's faster to use a ldr/str pair than add+ldmia/stmia for 2 registers. On ARM7TDMI a str pair is equally fast, so go for the simpler macro and use it for all ARMv4.

6d34e33b94 Speed up the predictor a little by using ldrd/strd on ARMv5+. This required shuffling around the register allocation somewhat. Performance on ARMv4 is unaffected.

d7e4e54bcb Reorder instructions to avoid pipeline stalls on ARMv6 wherever possible (sometimes using different registers to allow this). Speeds up the predictor by almost 20% on ARMv6 (overall speedup for -c1000 is 5%), and might also help a bit on ARMv5. ARMv4 speed is unaffected.

3761c0108c Branch optimisation in both C (giving hints to gcc - verified using -fprofile-arcs and gcov) and asm files. Biggest effect on coldfire (-c1000: +8%, -c2000: +5%), but ARM also profits a bit (less than 1% on ARM7TDMI, around 1% on ARM1136).

APE -c1000 is now usable on both PP502x and PP5002 (~138% realtime, they're on par now). Gigabeat F/X should also see an APE speedup.

2f50cd58b9 Codec memory reorganization 
Based on a patch by Tomasz Malesinski
* Merge Codec buffer and Malloc buffer into one large buffer.
* The new merged buffer is now 1MB on targets with lots of memory.
* Renamed codec_get_memory to codec_get_buffer and made it behave more. 
like plugin_get_buffer.
* Bumped Codec api and min api versions.
