This commit is the AVHWAccel analogue of commit
20f972701806be20a77f808db332d9489343bb78: It moves the private fields
of AVHWAccel to a new struct FFHWAccel extending AVHWAccel
in an internal header (namely hwaccel_internal.h).

All usages of ff_hwaccel_frame_priv_alloc() have the same pattern:
Check for whether a hwaccel is in use; check whether it needs
private frame-specific data; allocate the AVBuffer and set
it.
This commit modifies ff_hwaccel_frame_priv_alloc() to perform
this task on its own.
(It also seems that the H.264 decoder did not perform proper
cleanup in case the buffer could not be allocated. This has been
changed.)

libavcodec/hwconfig.h currently contains HWACCEL_CAP_* flags
as well as the definition of AVCodecHWConfigInternal and some
macros to create them.
The users of these two are nearly disjoint: The flags are used
by files providing AVHWAccels whereas AVCodecHWConfigInternal
is used by files providing codecs (for FFCodec.hw_configs).
This patch therefore moves these flags to a new file hwaccel_internal.h.

A filter needs formats.h iff it uses FILTER_QUERY_FUNC();
since lots of filters have been switched to use something
else than FILTER_QUERY_FUNC, they don't need it any more,
but removing this header has been forgotten.
This commit does this; files with formats.h inclusion went down
from 304 to 139 here (it were 449 before the preceding commit).
While just at it, also improve the other headers a bit.

internal.h doesn't rely on it; instead include it directly
in every user that needs it (a filter needing it is basically
equivalent to it using FILTER_QUERY_FUNC, i.e. a majority of
filters doesn't need it).

This file is only used by the greyedge filter and therefore
only compiled if said filter is enabled. This also allows
to remove a config_components.h inclusion, avoiding unnecessary
rebuilds.

Lots of video filters use a very simple input or output:
An array with a single AVFilterPad whose name is "default"
and whose type is AVMEDIA_TYPE_VIDEO; everything else is unset.
Given that we never use pointer equality for inputs or outputs*,
we can simply use a single AVFilterPad instead of dozens; this
even saves .data.rel.ro (8312B here) as well as relocations.
*: In fact, several filters (like the filters in vf_lut.c)
already use the same outputs; furthermore, ff_filter_alloc()
duplicates the input and output pads so that we do not even
work with the pads directly.

internal.h does not depend on video.h (and should not depend on it)
and therefore should not include video.h at all; instead all users
of video.h should include it directly.
Doing so also avoids unnecessary video.h inclusions in files that
don't need it, like most audio filters.

Don't include them implicitly via avcodec.h. This avoids
indirect avcodec.h inclusions in lavc/dirac.c, lavf/oggparsedirac.c,
and lavf/rtp(dec|enc)_vc2hq.c.

This avoids including lavc/codec_desc.h everywhere and thereby
forces users to include it directly instead of lazily and potentially
unknowingly relying on indirect inclusions.
Also add the proper inclusion to libavformat/demux.c, one of the
two files that actually use the new field.

Most of the inline functions in h264dec.h are only used

In WinRT mode, we use CreateThread instead of _beginthreadex.
CreateThread takes a LPTHREAD_START_ROUTINE function pointer,
which has got the signature DWORD WINAPI ThreadProc(LPVOID).
_beginthreadex takes a function with the signature
unsigned __stdcall func(void *).
DWORD is defined as an unsigned long, which is different type
from unsigned int, even if they have the same size on Windows.
This fixes build failures with Clang 16 and newer, where function
pointer type mismatches are a fatal error by default.

Use the GCC specific codepath for Clang in MSVC mode too.
This matches the condition used in a number of other places.
MSVC doesn't have a way to signal potential aliasing, while GCC
(and Clang) can use __attribute__((may_alias)) for this purpose.
When building with Clang in MSVC mode, __GNUC__ isn't defined but
_MSC_VER is as Clang primarily impersonates MSVC - but even then it
does support the GCC style attributes.
The GCC specific codepath uses av_alias, which expands to
the may_alias attribute if supported. The MSVC specific codepath
doesn't use av_alias so far (as MSVC doesn't support any
corresponding attribute).
This fixes a couple HEVC decoder tests when built with Clang 14 or
newer in MSVC mode (with issues observed on all of x86_64, armv7
and aarch64).

nvenc_store_frame_data() is always called with frame != NULL
(checked at the beginning of nvenc_send_frame());
in fact, frame is dereferenced unconditionally after the block
guarded by the check for frame. Therefore Coverity complains

The code currently presumes that a return value of AVERROR(ENOMEM)
implies that ac3hdr could not be allocated, so it need not be freed.
Yet any avpriv_ac3_parse_header() might allocate more than the
AC3HeaderInfo internally (it doesn't currently), so simply free
it unconditionally.
