Luca Barbato 22141917a9 Revert "h264: Properly set coded_{width, height} when parsing H.264." 
This reverts commit b47904d158.

coded_{width, height} overwrites width and height in avcodec_open and
it currently just report the non-lowres size.

Mans Rullgard 5cc2600964 dsputil: create 16/32-bit dctcoef versions of some functions 
High bitdepth H.264 needs 32-bit transform coefficients, whereas
dnxhd does not.  This creates a conflict with the templated
functions operating on DCTELEM data.  This patch adds a field
allowing the caller to choose the element size in dsputil_init()
and adds the required functions.

Mike ScheutzowandAnton Khirnov aa15e68721 Fix decoding of mpegts streams with h264 video that does *NOT* have b frames 
One of the causes of this bug is that the h264 parser defaults low_delay
to 1, but the h264 codec defaults low_delay to 0. Really Ugly.

After many hours of looking at this, I'm still not sure how has_b_frames
is *intended* to behave, but to me the implementation appears way more
complicated than it ought to be.

My patch relies on the encoder to set an optional field in the SPS. This
works for libx264 streams, but I'm not sure that all h264 encoders will
set it.

Ronald S. Bultje 4e987f8282 h264: correct border check. 
When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.

Oskar ArvidssonandRonald S. Bultje 19a0729b4c Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. 
This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

Preparatory patch for high bit depth h264 decoding support.

Oskar ArvidssonandRonald S. Bultje 6e3ef511d7 Add the notion of pixel size in h264 related functions. 
In high bit depth the pixels will not be stored in uint8_t like in the
normal case, but in uint16_t. The pixel size is thus 1 in normal bit
depth and 2 in high bit depth.
