8d857c5434 Add a few size checks when decoding rtjpeg blocks. 
Might avoid crashes in unlikely cases, but mostly avoids ugly artefacts
for partial frames.

0766291a66 Move "block" variable in rtjpeg decoder to context to ensure sufficient alignment 
for idct_put on architectures/compilers that have problems aligning on the stack.

86b0e9948b H264: Don't deblock if alpha or beta is 0. 
This ensures that the MMX loop filter is always bitexact with the C version.

fdb699de62 Fix passing of unaligned addresses to dsputil diff_bytes() by 
changeing calls to sub_left_prediction such that
the source frame data pointers are no longer offset to skip the initial
elements. This keeps them properly aligned for the subsequent call to diff_bytes.
Changes encoding offset to compensate.

aa5cfdfb4f Add offset argument to encode_422_bitstream() to control where 
in the source data array to start encoding.
Change all calls to pass zero for this new argument for equivalent behavior.

This is a restructure to support a forthcoming bug fix.

364f4a3620 Revert part of r18903: 
MLP DSP functions x86-optimized.
12.59% overall speedup in x86_32
 9.98% overall speedup in x86_64
compared to gcc 4.3.3

It breaks on x86_64 with PIC because the MANGLE macro appends (%%rip), which
is not wanted for labels.

f2a875db87 Move eatgq blocks array from the stack to the codec context and make sure 
it is aligned as necessary for DSPContext's idct_put.
Just aligning it on the stack would have been possible but less reliable
and without any real benefit.

7dfed8e1dc Fix for a problem with inverted sign of output data from ffvorbis decoder. 
Now the sign of audio samples in ffvorbis output is the same as in original
uncompressed audio file and this also allows the use of tiny_psnr to compare
ffvorbis with libvorbis/tremor.
