The FATE tests for MSVC versions older than 2013 are untested in FATE
and apparently are no longer supported.
This commit makes the configure process error out in case an older version
is used, and suggests to use a supported version of MSVC to compile.
This also changes the documentation to reflect this.
As discussed on IRC:
2018-05-12 19:45:16 jamrial then again, most of those were for old msvc, and i think we're not supporting versions older than 2013 (first one c99 compliant) anymore
2018-05-12 19:45:43 +JEEB yea, I think 2013 update 2 is needed
22:53 <@atomnuker> nevcairiel: which commit broke/unsupported support for msvc 2013?
23:23 <@atomnuker> okay, it was JEEB
23:25 <+JEEB> which was for 2012 and older
23:25 <+JEEB> and IIRC we no longer test those in FATE so that was my assumption
23:26 <+JEEB> 2013 is when MS got trolled enough to actually update their C part
23:26 <+JEEB> aand actually advertised FFmpeg support
23:26 <+JEEB> (although it was semi-failing until VS2013 update 1 or 2)

This does require libmysofa with today's latest commit (08f243d1ec).
They already had a pkg-config file, but the dependencies weren't setup right. Until now.
This should be included as `<lilv/lilv.h>`, same as is done in af_lv2.c.
Forcing the extra lilv-0 breaks platforms where the include dir is
`/usr/include/lilv/lilv.h` rather than
`/usr/include/lilv-0/lilv/lilv.h`.
The new include path works for both, because the `pkg-config --cflags`
includes `-I/usr/include/lilv-0`.
It exists, so why not use it? Helps one get rid of additional
search path related flags in addition to PKG_CONFIG_{PATH,LIBDIR}
when utilizing a cross-prefix separate from the sysroot.
This can "demux" .vpy files. Autodetection of .vpy scripts is
intentionally not done, because it would be a major security issue. You
need to force the format, for example with "-f vapoursynth" for the
FFmpeg CLI tools.
Some minor code copied from other LGPL parts of FFmpeg.
I did not find a good way to test a few of the more obscure VS features,
like VFR nodes, compat pixel formats, or nodes with dynamic size/format
changes. These can be easily implemented on demand.
Without properly grouping the checks, the second test would execute for
MSVC cl.exe, which results in configure getting stuck since cl.exe -? is
an interactive paginated help screen, waiting for input.

When using clang-cl it expects parameters passed in MSVC-style, so appropriate toolchain should be selected.
As soon as both clang and clang-cl report themselfs as "clang" with -v option the only chance to detect
clang-cl is passing -? option to both which is valid for clang-cl.exe and not for clang.exe.

Vanilla clang supports altmacro since clang 5.0, and thus doesn't
require gas-preprocessor for building the arm assembly any longer.
However, the built-in assembler doesn't support .dn directives.
This readds checks that were removed in d7320ca3ed, when
the last usage of .dn directives within libav were removed.
Alternatively, the assembly could be rewritten to not use the
.dn directive, making it available to clang users.

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.
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.
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.
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.
