We don't know if the protocol used is referring to a local file or a remote
resource, so it is better to simply use slash as separator which works all the
time. (well, except in very special cases when the user specified a \\?\ path)
Fixes ticket #9780.

Overriding unknown layouts with the negotiated layout is OK, but the number of
channels should match with what was negotiated.

The 2 which has been changed to an 8 in the array length expression is
the maximum value of sps_bitdepth_minus8. This was missed when updating
to VVCv2, which increased this maximum from 2 to 8.

The size variable here is taken as gospel for the bounds of the input
buffer in later logic. Clamp it to ensure that the returned region
does not extend past that allocated in the underlying GetBitContext,
even in the case entry point offsets are signalled in the bitstream.
Also assert this for good measure.

num_units_in_tick and time_scale are both 32-bit unsigned integers.
Storing them as ints was causing overflows.

Note that the config.sh file is left without a shebang, this file is
supposed to be sourced into the current environment.
This commit is purely cosmetic.

The implicit interpreter is dependent on the environment, and isn't
guaranteed to be /bin/sh. Some packagers call this script directly, and
in certain environments such as containers using qemu-user through
binfmt_misc emulation on Linux it doesn't fallback to /bin/sh.
To fix these cases we add the interpreter explicitly.

The preferred way to use LTO is --enable-lto but often times packagers
still end up with -flto in cflags for various reasons. Using grep
on binary object files is brittle and relies on specific object
representation, which in the case of LLVM bitcode, debug information or
other intermediary formats can fail silently.
This patch changes the check to a more commonly used define for GCC
style compilers. More checks may be needed to cover other potential
compilers that don't use the __BYTE_ORDER__ define.

Invalid input files may contain film grain metadata which survives
ff_h274_film_grain_params_supported() but does not pass
av_film_grain_params_select(), leading to a SIGSEGV on hevc_frame_end().
Fix this by duplicating the av_film_grain_params_select() check at frame
init time.
An alternative solution here would be to defer the incompatibility check
to hevc_frame_end(), but this has the downside of allocating a film
grain buffer even when we already know we can't apply film grain.

This allows one complex filtergraph's output to be sent as input to
another one, which is useful in certain situations (one is described in
the docs).
Chaining filtergraphs was already effectively possible by using a
wrapped_avframe encoder connected to a loopback decoder, but it is ugly,
non-obvious and inefficient.
The decision whether -apad actually does anything is made based on muxer
properties, and so more properly belongs there. Filtering code only
receives the result.
Instead pass the encoder through a newly-added output options struct,
analogous to previously added input options.
Will allow decoupling filtering from encoding in future commits.
Use context_initialized from the underlying MpegEncContext
instead. Also don't check before ff_mpv_common_end()
in mpeg_decode_end().
