The configure check already had fallback for the previous version
of glslang, which had different requirements for flags.
This commit simply moves the flags needed for glslang 13 to the
fallback, while first trying to use new flags for glslang 14.
This drops support for ~3 year old glslang versions, which
I'm not sure had the complete C API we're using anyway.
The filename is freed with the OptionsContext and therefore
there will be a use-after-free when reporting the filename
in print_stream_maps(). So create a copy of the string.
This is a regression since 8aed3911fc.
fate-lavf-mkv_attachment exhibits it (and reports a random nonsense
filename here), but this does not make the test fail (not even with
valgrind; only with ASAN, as it aborts on use-after-free).

To do this, allocate AVFilterGraphInternal jointly with AVFilterGraph
and rename it to FFFilterGraph in the process (similarly to
AVStream/FFStream).
The AVFilterGraphInternal* will be removed on the next major version

This fixes the previous commit and adds more cases (DCT-I and DST-I).
I am holding off on defining a scale parameter for FFTs as I'd like

If a custom layout is equivalent to a native one, check if it matches one of the

This together with adjusting the inclusion define allows for the
build to not fail with latest Vulkan-Headers that contain the
stabilized Vulkan AV1 decoding definitions.
Compilation fails currently as the AV1 header is getting included
via hwcontext_vulkan.h -> <vulkan/vulkan.h> -> vulkan_core.h, which
finally includes vk_video/vulkan_video_codec_av1std.h and the decode
header, leading to the bundled header to never defining anything
due to the inclusion define being the same.
This fix is imperfect, as it leads to additional re-definition
warnings for things such as
VK_STD_VULKAN_VIDEO_CODEC_AV1_DECODE_SPEC_VERSION. , but it is
not clear how to otherwise have the bundled version trump the
actually standardized one for a short-term compilation fix.
A lot of changes and fixes to channel layout parsing, notably
- get rid of dynamic allocation of channel positions
- signal unimplemented speaker positions as unknown instead of failure, but
warn the user about it
- native order, and that a single channel only appears once was always assumed
for less than 64 channels, obviously this was incorrect

It should be available in all relevant modern compilers and will allow
us to use features like anonymous unions.
Note that stdatomic.h is still emulated on MSVC, as current versions
require the /experimental:c11atomics, and do not support
ATOMIC_VAR_INIT() anyway.
According to ITU-T H.265 7.4.2.1 this byte sequence should not appear in a
NAL unit but in practice in rare cases it seems it does, possibly due to buggy
encoders. Other players like VLC and Quicktime seem to be fine with it.
Currently when this sequence is found it is treated as if the next start code
has been found and the NAL unit gets truncated.
This change limits the code to only look for first start code 0x0000001 or
first escape 0x000003.
Sadly i can't share the original source file with the issue but the first
80 bytes of the NAL unit looks like this:

I generated a DXV2 file with an interesting alpha channel using
Adobe Media Encoder 2015 and compared decoding it using Resolume Alley
and ffmpeg. Similarly to DXV3 files, Alley expects premultiplied alpha
and ffmpeg matches its decoding more closely when it does the same.

This change decouples the frame dimensions from avctx, which is useful
for DXV decoding, and fixes incorrect behavior in the existing
implementation.

We currently mostly do not empty the MMX state in our MMX
DSP functions; instead we only do so before code that might
be using x87 code. This is a violation of the System V i386 ABI
(and maybe of other ABIs, too):
"The CPU shall be in x87 mode upon entry to a function. Therefore,
every function that uses the MMX registers is required to issue an
emms or femms instruction after using MMX registers, before returning
or calling another function." (See 2.2.1 in [1])
This patch does not intend to change all these functions to abide
by the ABI; it only does so for ff_simple_idct_mmx, as this
function can by called by external users, because it is exported
via the avdct API. Without this, the following fragment will
assert (on x86_32, as ff_simple_idct_mmx is not used on x64):
int16_t __attribute__ ((aligned (16))) block[64];
AVDCT *dct = avcodec_dct_alloc();
dct->idct_algo = FF_IDCT_AUTO;
avcodec_dct_init(dct);
dct->idct(block);
av_assert0_fpu();

The PPS should be used instead of the SPS to get the current picture's
dimensions. Using the SPS can cause issues if the resolution changes
mid-sequence. In particular, it was leading to invalid memory accesses
if the resolution decreased.
Patch replaces sps->{width,height} with pps->{width,height}. It also
removes sps->{width,height}, as these are no longer used anywhere.
