1284c127f8 Introduce likely() and unlikely() macros, use to give gcc hints about which branch is likely to be taken in a conditional, use them in the midi player for a small speedup, use instead of similar EXPECT macros in tremor and use in mpegplayer

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles. 
Many #include lines adjusted to conform to the new standards.

2a5053f58c Several tweaks and cleanups: * Use .rept instead of repeated macros for repeating blocks. * Use MUL (variant) instead of MLA (variant) in the first step of the ARM scalarproduct() if there's no loop. * Unroll ARM assembler functions to 32 where not already done, plus the generic scalarproduct().

77934cbc96 Compile-time choice between 16 bit and 32 bit integers for the filters. 32 bit filters are faster on ARMv4 (with assembler code), so use them there. Nice speedup on PP and Gigabeat F/X.

545b51e2e4 ARMv4 unsigned integer division: Using an overflow-safe comparison method in the main calculation allows to put back the 1.5 cyle (average) optimisation. Shaved off another instruction, as we don't need the remainder. * Use the very efficient ffs algorithm from ffs-arm.S for dividing by a power of 2.

fe04e40be7 Further optimised (vs. libgcc) unsigned 32 bit division for ARMv4 (based on the ARMv5(+) version from libgcc), in IRAM on PP for better performance on PP5002, and put into the codeclib for possible reuse. 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.

528fe442fc New recording setting to configure how mono recordings are made. Previously, this was always L+R, which was kinda silly if your signal was on L only. This setting allows for L, R or L+R. SWCODEC only for now, to be added for HWCODEC (although that will only be L and L+R probably)

d1b19be423 Various speedups: (1) Put actual decoding functions into IRAM on PP5002. (2) Put the insane filter buffer into IRAM on coldfire and PP502x (just for completeness, as long as there's no better use). (3) Use the ARMv6 'ssat' instruction for saturation on Gigabeat S.
