Move H264 dsputil functions into their own struct

This moves the H264-specific functions from DSPContext to the new
H264DSPContext. The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by...

Remove DECLARE_ALIGNED_{8,16} macros

These macros are redundant. All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

AltiVec version of h264_idct(8)_dc_add
Patch by David Conrad lessen42 A gmail P com

Originally committed as revision 16442 to svn://svn.ffmpeg.org/ffmpeg/trunk

Disable usage of ff_h264_idct_add_altivec since AltiVec versions of h264_idct_add16,
h264_idct_add16intra, h264_idct_add8 need to be implemented.

Add C version of ff_h264_idct8_dc_add in AltiVec so that ff_h264_idct8_add_altivec
can be used.

Remove AltiVec vector declaration compiler compatibility macros.
The original problem was that FSF and Apple gcc used a different syntax
for vector declarations, i.e. {} vs. (). Nowadays Apple gcc versions support
the standard {} syntax and versions that support {} are available on all...

restore GCC3 support

part 2/2 of fixing Altivec-accelerated H264 luma inloop filter

In h264_deblock_q1, the result of the deblock needs to be kept to
be used in future deblocks, so return this value now.

Also change the sign of tc0 vector: It is really a signed value, so
treat it as such until after the >=0 check;...

Use a faster way to compute 255-val: Instead of creating a vector of
all 255s, and then doing the subtraction, nor of the vector with itself: saves
one instruction and a register.
