4693b031a3 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
non-h264 code.

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.

80a61f08d2 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
relevant Mac OS X versions. Thus the greater compatibility is no longer
worth cluttering the code with macros.

22fa38f0c8 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;
then, at that point, after being masked, it can be treated as unsigned.
