On X86 windows, asflags weren't actually ever used for anything,
since assembling used x86asflags instead, and that flags list
had -DPIC already.
This fixes building shared libraries with clang for arm/aarch64
windows. (This wasn't an issue when in msvc mode before, since
we don't try to enable pic at all there, since the msvc armasm
assembler fails on our pic constructs there.)

We skipped adding it to cflags for mingw/cygwin configurations
where the compiler either complains loudly or even errors out;
do the same for target_os=win32, for the case when building with
clang in msvc mode.
This wasn't needed for the actual msvc before, since msvc uses
msvc_common_flags to filter out this flag from cflags.
When building with clang in msvc mode, no such filter is used.

libgsm never installed more than a single header, the headers installed into
the gsm/ subdirectory by some distros are private. Who started this nonsense
is a mystery, but it got cargo-culted around ever since.
Build h2645_parse.o with it, as every hevc_ps dependency also needs it.
This is more in line with h264's h264parse module.

This helper is split off check_pkg_config(), setting only the pkg CFLAGS
and extralibs. This is useful for checks that do not require or do not
benefit from setting global CFLAGS.

The filter supports two inputs and (implicitly) scaling the second input
during composition, unlike the software overlay.
The code has been separated into common interface and qsv overlay
implementation. The common part mainly creates the qsv session and
manages the surface which is nearly the same for all qsv filters.
So the qsvvpp.c/qsvvpp.h API can be used by other QSV vpp filters
to reduce code redundancy.
Usage:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=eof_action=repeat:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M
-c:v h264_qsv -y out.h264
Two inputs should have different sizes otherwise one will be completely
covered or you need to scale the second input as follows:
-hwaccel qsv -c:v mpeg2_qsv -r 25 -i in.m2v -hwaccel qsv -c:v h264_qsv
-i in.h264 -filter_complex
"overlay_qsv=w=720:h=576:x=(W-w)/2:y=(H-h)/2" -b 2M -maxrate 3M -c:v
h264_qsv -y out.h264

Add common filters of the qsv vpp features including scale,denosie,
deinterlace,frc,crop and procAmp.
Performance will be significantly reduced in the test if using cascade
mode just like qsv framerate + qsv scale + qsv deinterlace + qsv denoise in
separated way no matter in system or video memmory cases.
And the code is so redundant because so much the same just as session and
surface's creation and management.
So we add a common qsv filter.
Usage:
-hwaccel qsv -c:v h264_qsv -r 25 -i in -vf
vpp_qsv=w=iw/2:h=400:deinterlace=1:framerate=60:detail=50:denoise=50
-b 2M -maxrate 3M -c:v h264_qsv -y out.h264

This avoids having to use pseudo relocations.
The version script used for exporting functions is skipped as soon
as the set of object files contains symbols marked with dllexport,
therefore we need to use makedef to produce the full list of symbols
to be exported.

The toolchain for this target is unmaintained since many years.
While it has been continuously build tested on fate, it hasn't
actually been tested at runtime since many, many years (and back
then, only a few codecs in libavcodec were tested).
So far, keeping support for it has been mostly effortless, but
the compiler does seem to have issues with dllimported data symbols,
ending up as internal compiler errors in some cases. Instead of
jumping through further hoops to work around that, just remove the
target.

This applies a specific fixup to some Bluray streams which contain
redundant PPSs modifying irrelevant parameters of the stream which
confuse other transformations which require correct extradata.
A new single global PPS is created, and all of the redundant PPSs
within the stream are removed.
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.

These variables might be set from a previous probe run, but one or the
other program that is probed for may not grok the flags, resulting in
errors during assembling when the values of those variables are passed
to the assembler.
Also employ this mechanism to pass $libdir to the runtime library search
path if rpath is enabled. This fixes underlinking of some test binaries
on some systems.
