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.

76027b5951 libtremor: correct constraint for coldfire asm, swap can only be used on data registers.

dfac9503eb libtremor: tweak a hot function for codebook decoding, mostly moving pointer lookups outside the loop. Speeds up decoding by 3-6% on Coldfire and a small speedup on arm too

01f91ed14d Factor out sane code list bisection code and use instead of insane code, clean up some tests for readability's sake. Gives a small speedup on h300 (coldfire, 0.1-0.6MHz) and a tiny speedup on gigabeat s (armv6 0.1-0.2MHz), no real difference on PP.

9e45b27e08 Assembler optimised bitreverse for ARM, again a little bit faster and smaller. * Separated 'x' and 'ret' gives gcc a bit more freedom regarding register allocation (except on coldfire where it doesn't matter).

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
