qsvdec: split off some code that will be shared with the encoder
Conflicts:
libavcodec/Makefile

Merged-by: Michael Niedermayer <michaelni@gmx.at>
Sufficiently new nvenc hardware (GM20x or later) has support for H.265
encoding. This works the same as the H.264 encoder except the
codec parameters are different.
Due to the fact that common codec parameters are not shareable, there's
quite a bit of conditional logic you'd wish we could do without, but
such is life.

The AC3DecodeContext has a float (USE_FIXED=0) and an integer
(USE_FIXED=1) variant, both of which can be present in the same binary.
This is not only very confusing, but it also breaks horribly, when one
variant is used by code expecting the other.
This currently happens, because eac3dec.c is only compiled for the float
variant, but also used from ac3dec_fixed.c, which uses the integer
variant.
The result is memory corruption, leading to crashes.
So compile eac3dec.c once for each variant and adapt it, so that it
works with the integer variant.
A loss of precission and scaling bug has been fixed by the committer

See: 6ac3c8c6a0
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This fixes builds with vc1_parser enabled without vc1_decoder. All
the vc1_decoder object files were included in the vc1_parser line
in libavcodec/Makefile before, but architecture specific object files
for vc1_decoder were not.

Compared to existing, common opensource H264 encoders, this can be
useful since it has got a different license (BSD instead of GPL).
Performance- and qualitywise it is comparable to x264 in ultrafast
mode.
Hooking it up as an encoder in libavcodec also simplifies comparing
it against other common encoders.
This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI
changes frequently, only releases are supported.
To take advantage of the OpenH264 patent offer, the OpenH264 library
must not be redistributed, but downloaded at runtime at the end-user's
system.
