The latter can do everything the former can do, but also handle conditions
the former cannot like multiple header #includes and checking for headers
and functions in a single test program, which is necessary for certain
library tests.
cuvid/nvdecode also supports mpeg1, mpeg2, h.263/mpeg4-asp and mjpeg.
It should, in theory, also support wmv3 via the vc1 support, given
that vdpau supports this. However, it failed to play wmv3 samples
which vdpau played correctly, so I'm not sure what to make of it.

For some reason, when compiling with gcc-asan and a recent enough gcc
version(seen on 5.3+ so far), linking dlopen works without -ldl, but
dlsym fails with:
undefined reference to symbol 'dlsym@@GLIBC_2.2.5'
So this patchs checks for both dlopen and dlsym to work for determining
if -ldl is needed.
Commit 2b1d316ff6 made nvenc depend on
LoadLibrary, but the availability of the latter was never checked.
This fixes nvenc on Windows platforms

As Nvidia has put the most recent Video Codec SDK behind a double
registration wall, of which one needs manual approval of a lenghty
application, bundling this header saves everyone trying to use NVENC
from that headache.
The header is still MIT licensed and thus fine to bundle with ffmpeg.
Not bundling this header would get ffmpeg stuck at SDK v6, which is
still freely available, holding back future development of the NVENC
encoder.
Windows versions earlier than XP are not supported.
Should fix compilation of command line tools.

This allows doing this redirection, if building with clang against
old enough MSVC headers that lack strtoll (2012 and older).

directive (while binutils supports it for all targets).

This reverts commit cb8646af24.
This change has brough more issues than benefits, between compilation
time failures depending on flags used and code miscompilation causing
runtime crashes.
See the "[PATCH 2/2] configure: Enable GCC vectorization on ≥4.9"
thread in the ffmpeg-devel mailing list for the relevant discussion.
Visual Studio 2015 Update 3 introduced a new SSA optimizer, however
it unfortunately causes miscompilations. Until it is fixed, the new
optimizations are disabled and should be re-checked on subsequent
compiler releases.
Fixes recent FATE failure of fate-lavf-pam on VS2015.
While it is less featureful (and slower) than the built-in H264
decoder, one could potentially want to use it to take advantage
of the cisco patent license offer.
