libdemac: ARMv7 assembler optimisation for the filters, tested on Nokia N900. Speedup is 2.1x for -c5000 compared to the ARMv6 asm. Note that actually compiling it on device requires hand-assembling the 'vadd' and 'vsub' instructions due to a bug in binutils 2.18.50, and making the standalone decoder use it requires Makefile and demac_config.h hacks.
