7943355485 ff_fft_init now double checks that the system has mm3dnow.h before 
checking if the cpu can do 3dnow at all. This bug caused amd cpu's
without sse to not have a working fft function. Ie no wma, cook or
vorbis decoder.

a949360163 * Allocating 16 bytes more for the MEMALIGN_HACK is enough. There's no 
need for 1 more extra byte.

* Checking whether the to be allocated size is larger than INT_MAX,
doesn't assure that size+16 bytes for the MEMALIGN_HACK isn't larger
than INT_MAX.

* malloc might return NULL. Checking for it before using that pointer
seems like a good idea.

e71bcc3798 flacenc - rice param search patch by (Justin Ruggles jruggle earthlink net 
1) search for optimal rice parameters and partition order. i also
modified the stereo method estimation to use this to calculate estimated
bit count instead of using just the pure sums.

2) search for the best fixed prediction order

3) constant subframe mode (good for encoding silence)

Note that the regression test for the decoded wav file also changed.
This is due to FFmpeg's FLAC decoder truncating the file, which it did
before anyway...just at a different cutoff point.  The generated FLAC
files are still 100% lossless.

With this update, FFmpeg's FLAC encoder has speed and compression
somewhere between "flac -1" and "flac -2".  On my machine, it's about
15% faster than "flac -2", and about 10% slower than "flac -1".  The
encoding parameters are identical to "flac -2" (fixed predictors, 1152
blocksize, partition order 0 to 3).

4f8ff17e75 The AAC frame header uses 13 bits for the frame size, so the buffer should 
have room for such a frame.  A frame that large seems unlikely in a valid
file, but leaving room for it spares us the need to check it elsewhere.
Moving the buffer to the end of the struct made debugging this easier.
