7f92db14f9 g723_1: save/restore excitation with offset to store LPC history 
The same buffer with saved data is used later in LPC reconstruction, so
it should have some head space for LPC history.

c728518b3c x86: fft: fix imdct_half() for AVX 
Some calculations were changed in b6a3849 to use mmsize, which was not correct
for the AVX version, which uses INIT_YMM and therefore has mmsize == 32.

Fixes Bug 341.

af500c08bb dct-test: always link with aandcttab.o 
This allows building dct-test even if aandcttab.o is not pulled in
by any enabled codec.  The DCT with which these tables are used does
not use them directly, so building it without the tables is possible.

cf5781fad0 vp8: pack struct VP8ThreadData more efficiently 
Reordering the members in this struct reduces the holes required
to maintain alignment.  With this order, the only remaining, and
unavoidable, hole is 3 bytes following left_nnz.

ec7c501ed5 x86: remove libmpeg2 mmx(ext) idct functions 
These functions are not faster than other mmx implementations on
any hardware I have been able to test on, and they are horribly
inaccurate.  There is thus no reason to ever use them.

998170913c ARM: use standard syntax for all LDRD/STRD instructions 
The standard syntax requires two destination registers for
LDRD/STRD instructions.  Some versions of the GNU assembler
allow using only one with the second implicit, others are
more strict.

b6a3849adb fft: port FFT/IMDCT 3dnow functions to yasm, and disable on x86-64. 
64-bit CPUs always have SSE available, thus there is no need to compile
in the 3dnow functions. This results in smaller binaries.

b829b4ce29 h264: convert loop filter strength dsp function to yasm. 
This completes the conversion of h264dsp to yasm; note that h264 also
uses some dsputil functions, most notably qpel. Performance-wise, the
yasm-version is ~10 cycles faster (182->172) on x86-64, and ~8 cycles
faster (201->193) on x86-32.

f3eb008343 eamad/eatgq/eatqi: call special EA IDCT directly 
These decoders use a special non-MPEG2 IDCT.  Call it directly
instead of going through dsputil.  There is never any reason
to use a regular IDCT with these decoders or to use the EA IDCT
with other codecs.

This also fixes the bizarre situation of eamad and eatqi decoding
incorrectly if eatgq is disabled.

b3c5ae5607 fft: rename "z" to "zc" to prevent name collision. 
Without this, cglobal will expand "z" to "zh" to access the high byte
in a register's word, which causes a name collision with the ZH(x) macro
further up in this file.
