- there is no need for kCVImageBufferColorPrimaries_ITU_R_2020 checks,
it's done at runtime
- VideoToolbox presence is now checked with check_apple_framework()
- link to CoreServices is only done when videotoolbox is enabled
$headers is a variable set in the context of other functions (we don't
use the "local" keyword in our scripts, so those variables are global).
Currently, when checking for AVFoundation/AVFoundation.h, the actual
enabled header is math.h.
Similarly, when testing for QuartzCore/CoreImage.h, the actual enabled
header is CoreGraphics/CoreGraphics.h.
This is completely broken and may be the reason why these checks are
made in random places.
On ARM platforms, accessing the PMU registers requires special user
access permissions. Since there is no other way to get accurate timers,
the current implementation of timers in FFmpeg rely on these registers.
Unfortunately, enabling user access to these registers on Linux is not
trivial, and generally involve compiling a random and unreliable github
kernel module, or patching somehow your kernel.
Such module is very unlikely to reach the upstream anytime soon. Quoting
Robin Murphin from ARM:

As a result, the alternative is to use the Performance Monitoring Linux
API which makes use of these registers internally (assuming the PMU of
your ARM board is supported in the kernel, which is definitely not a
given...).
While the Linux API is obviously cross platform, it does have a
significant overhead which needs to be taken into account. As a result,
that mode is only weakly enabled on ARM platforms exclusively.
Note on the non flexibility of the implementation: the timers (native
FFmpeg vs Linux API) are selected at compilation time to prevent the
need of function calls, which would result in a negative impact on the
cycle counters.
This simplifies incoming SDL related changes by removing potential
mismatching states of sdl and sdl2 variables. Since a component can have
all kind of states (such as unset, enabled, disabled or requested),
keeping these variables in sync manually in random places is not robust.
This patch makes the libvmaf filter use pkg-config to detect
and link to libvmaf.

If using the winstore compat library, a fallback LoadLibrary
function does exist, that only calls LoadPackagedLibrary though
(which doesn't work for dynamically loading d3d11 DLLs).
Therefore explicitly check the targeted API family instead.
Make this check a reusable HAVE_* component which other parts
of the libraries can check when necessary as well.

The pkg-config file is relatively new (2013), so some distros might
not have it yet. And the -lstdc++ being required for the static lib
is only present since the last release in December 2016.
libvorbis comes with pkg-config files since at least v1.0.1, way back in 2003.
We need the two checks for vorbis and vorbisenc because we use functions from
both and Xiph considers them separate libraries.
The check is inverted (vorbis first then vorbisenc) because add_extralibs()
prepends to EXTRALIBS instead of appending. For both shared and static linking
the order didn't seem to matter anyway, testing with MinGW.

When targeting the UWP API subset, the LoadLibrary function is not
available (and the fallback, LoadPackagedLibrary, can't be used to
load system DLLs). In these cases, link directly to the functions
in the DLLs instead of trying to load them dynamically at runtime.
Merges Libav commit fd1ffa1f10.

This also adds support to avconv (which is trivial due to the new
hwaccel API being generic enough).
The new decoder setup code in dxva2.c is significantly based on work by
Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites.
Merges Libav commit f9e7a2f95a.
Also adds untested VP9 support.
The check for DXVA2 COBJs is removed. Just update your MinGW to
something newer than a 5 year old release.

If the first assembler to be probed is an old nasm build, X86ASM_DEPFLAGS
will be set and remain so after yasm is ultimately used as fallback.
This results in yasm being called with said nasm specific flags and failing
during actual object assembly but not with configure sanity checks.

NASM is more actively maintained and permits generating dependency information
as a sideeffect of assembling, thus cutting build times in half.
