Behaves like existing convolution filter.

Similar indirections are used for the -o compiler/assembler flag to
account for differences in compiler/assembler syntax. For x86asm half
the infrastructure for doing the same currently exists unused.
Finish and use that infrastructure for consistency.

Also use that to support mapping VAAPI to Beignet.

Behaves like the existing avgblur filter, except working on OpenCL
hardware frames. Takes exactly the same options.

This can remove units with types in or not in a given set from a stream.
For example, it can be used to remove all non-VCL NAL units from an H.264 or
H.265 stream.

Use it as the set of codec IDs supported by the trace_headers BSF.

With GCC, request it to maintain 16 byte alignment, and the existing
entry points already align it via attribute_align_arg.

With clang, do the same as for mingw; disable the aligned stack
and let the assembly functions that require it do the alignment
instead.

If we'd enable a 16 byte aligned stack, clang/llvm would also assume
that alignment everywhere and produce code that strictly requires it.
That would require adding realignment (via attribute_align_arg) on every
single public library function or enable -mstackrealign (which does the
same on every single function).

Also relatedly; the parameter currently tested (-mllvm
-stack-alignment=16) hasn't actually been supported for quite some
time; current clang versions use -mstack-alignment=16 for the same.
Actually testing for that parameter would be a different change
though, since it has a real risk of changing behaviour on any other
platform where clang is used.

Previously the bit pattern for the endianness test was declared as a
global, instead of a local, variable. This ensures that the pattern
appears unchanged in the object file and is not optimized out.

Fail if AMF is requested but unavailable, as we do for all
other external libraries that need to be explicitly enabled.

Right now, if someone configures ffmpeg with for example --enable-nvenc they will
get an error message complaining about missing cuda.
This is very confusing and already has lead people into installing the CUDA SDK,
even though it's not what they need.

This will make it complain about ffnvcodec instead.

External headers are no longer welcome in the ffmpeg codebase because they
increase the maintenance burden. However, in the NVidia case the vanilla
headers need some modifications to be usable in ffmpeg therefore we still
provide them, but in a separate repository.

The external headers can be found at
https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git

Fate-source is updated because of the deleted files, and dynlink_loader.h
license headers were updated with the standard FFmpeg headers.

The GCC generated import libraries don't work properly when being imported
by MSVC, resulting in missing symbols at runtime.

This reverts commit 67c72f08.

While the linker produced import libraries might work with MSVC in
simple test cases, they don't if e.g. linking to multiple GNU ld
produced import libraries at the same time. (They end up importing
functions from the wrong libraries.) The ones produced by dlltool
work fine though.

This issue was pointed out by Hendrik Leppkes.
