Should prevent some options from being added to cflags when they
don't exist and the compiler only warns about it.

The library has several dependencies that vary between systems.
Their pkg-config properly lists them all.

Two of them are missing it in their pkg-config file, so adding it
here is a workaround until said pkg-config files are fixed.

The libavformat API is not suitable for exporting output devices as muxers.
Some practical problems are e.g. lack of timing/synchronization mechanisms
or interaction with output-specific features.
Correct typo in signalstats filter section and qualify description for variable
in select filter.

The public functions av_alloc_vdpaucontext() and
av_vdpau_alloc_context() are allocating AVVDPAUContext
structure that is supposed to be placed in avctx->hwaccel_context.
However the rest of libavcodec/vdpau.c uses avctx->hwaccel_context
as struct VDPAUHWContext, that is bigger and does contain
AVVDPAUContext as first member.
The usage includes write to the new variables in the bigger stuct,
without checking for block size.
Fix by always allocating the bigger structure.

Since this machine type is 5 chars while the existing ones only
were 3 (which the regexp assumed), the regexp has to be extended
a little.

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.
This fixes building shared libraries with clang in msvc mode.
