fdba370f8a h264: fix HRD parameters parsing
The bit_rate_value_minus1 and cpb_size_value_minus1 elements
allow a wider range than get_ue_golomb() supports.  This
adds a get_ue_golomb_long() function supporting up to 31
leading zeros, which is the maximum for these syntax
elements, and uses it in decode_hrd_parameters().

be1242a3f2 h264: fix detection of optional trailing PPS elements
The PPS may contain a few trailing elements whose presence is
only signalled by data remaining after the the mandatory part
has been parsed.  The current code fails to take into account
the rbsp_trailing_bits() when deciding whether to parse these
optional elements.  Assuming no unnecessary padding bytes are
passed to this function, the optional elements are present if
either more than 8 extra bits remain or the remaining bits do
not form a valid rbsp_trailing_bits() after the mandatory PPS
elements have been parsed.

c90b94424c 4:4:4 H.264 decoding support
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

fcc0224e4f Add support for higher QP values in h264.
In high bit depth, the QP values may now be up to (51 + 6*(bit_depth-8)).

Preparatory patch for high bit depth h264 decoding support.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

00d1e96bf4 H.264 decode: support cropping up to 28 pixels in interlaced mode.
Contrary to progressive, just being able to crop up to 14/15 pixels
is not enough to encode all supported resolutions, and the new
behaviour is also consistent with e.g. MPEG-2 etc.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.
