Because of ffio_ensure_seekback() a seek error normally should only happen if
the end of file is reached during checking for the junk run-in. Also use proper
error code.

We are protecting the checked buffer with ffio_ensure_seekback(), so if the
inner check fails with a seek error, that likely means the end of file was
reached when checking for the next frame. This could also be the result of a
wrongly guessed (larger than normal) frame size, so let's continue the loop
instead of breaking out early. It will end sooner or later anyway.

Otherwise the subsequent ffio_ensure_seekback calls destroy the buffer of the
earlier. The worst case ~66kB seekback is so small it is easier to request it
entirely.

Do this by attaching the FilterGraph directly to more permanent

Its existence is a remnant of (libavcodec's) lock-manager API
which has been removed in a04c2c707d.
There is no need to use the same lock for avisynth, chromaprint
or tls, so switch to ordinary static mutexes instead.

Most users of ff_adts_header_parse() don't already have
an opened GetBitContext for the header, so add a convenience
function for them.
Also use a forward declaration of GetBitContext in adts_header.h
as this avoids (implicit) inclusion of get_bits.h in some of
the users that now no longer use a GetBitContext of their own.

When the external allocator is used for dynamic frame allocation, only
video memory is supported, the SDK doesn't lock/unlock the memory block
via Lock()/Unlock() calls.

When AVHWFramesContext.initial_pool_size is 0, a dynamic frame pool is
required. We may support this under certain conditions, e.g. oneVPL 2.9+
support dynamic frame allocation, we needn't provide a fixed frame pool
in the mfxFrameAllocator.Alloc callback.
