2e6d604bb6 Stop hiding errors by redirecting stderr to /dev/null. If we really need to do re-introduce somewhere we should rather make it dependent on the V variable so that make V=1 would still show the error and only "normal" builds would hide it.

c3615119ba Don't read a full byte if less than 8 bits are available. The change doesn't fix any problem samples, but the current code makes no sense. Also some spelling corrections in debugfs and comments.

2557251351 Correctly implement remaining portions of ffmpeg's r8627 that I'd forgotten about. This fixes a table overflow in low bitrate files that use noise coding, and in theory should be substantial improvement, but I haven't found any files were it makes a difference.

d909eee0ce Commit fix by Tom Ross in FS#7488 wherein a silly mistake noise coding initialization is corrected. This sample alone has probably resulted in more WMA fixes then all other combined and I suspect there will still be at least one more.

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles.

46f85c4c54 Combine the Vorbis, WMA and AAC IMDCT functions and put them into the codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs.

1334738071 Use Tremor IMDCT for WMA. Gives a ~20% speedup on ARM and coldfire. All my test samples gave equivilent or better accuracy (>>16 bit), but there may still be problems. Code becomes somewhat less readable since the IMDCT has bits of Vorbis in it, but this is not a serious issue and the old ffmpeg transform remains in SVN if anyone wants it. Also, WMA now passes Vorbis as the fastest transform codec on ARM, although MPC remains the fastest lossy codec overall.

a06f651c3e Put the WMA windowing and output buffer into IRAM on targets with > 96KB of it. Improves 192k WMA decoding speed by about 2MHz on PP5024, and maybe saves some more when applying DSP.

ff9f3f8c04 Revert r14786 which resulted in a substantial reduction in accuracy to save a 7.6KB of RAM. Accuracy should be greatly improved now, and if we want to make that trade off again, I think of better ways to do it.
