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.

or a single loop similar to what mplayer uses

Woops, this file was supposed to be added in r5556: "Move initialisations and internal symbols in allformats.h"

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.

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).

Added loop filtering as ersatz for overlap filter (improves picture quality for coarse quantization).
