67efbc1387 libtremor: 
Merge in upstream revision 17375.
This removes tremor's internal ogg code and now uses libogg instead so a bunch of changes are just adjusting to the new api. Also brings in improvements to vorbisfile which fixes FS#10484.
Disabled a lot of unused code in the libogg files and moved some small functions into the ogg.h header so they can be inlined. Some small tweaks to fix warnings.

9929512682 ARM9 optimized synth_full for libmad. Speeds up mp3 decoding by an even 2 MHz on all ARM9 and later devices. Note this is only optimized for arm9 (non-E), although it is faster on later devices. An arm9E/11 version will be needed for optimal performance on newer devices.

b965c24c0b ffmpeg flac does actually support up to 192k sample rates, and my test file seems to decode fine, so lets enable it. Note that using 192khz is over 6 times slower then 44.1khz on my test file, so I recommend sticking to more reasonable bitrates.

f51189fa4d Commit FS#11709 by me. Introduces ARMv5E optimized iQMF for atrac3 based on packed multiply instructions. Additionally, improves scheduling on arm9 and arm11 and forces cache alignment of buffers on all targets. Accuracy is slightly reduced, but still greater then 16 bit. Clip+ CPU clock required for LP2 files decreases by 13MHz and ARM11 by 18MHz. No performance or accuracy changes on armv4 or non-arm.
