as default. Otherwise, mark every stream as dependent.

The call to ff_exp2fi() here always uses arguments in the normal
range, so that the branches in ff_exp2fi() are unnecessary.
This is so because JPEG2000 itself only supports up to
128 bits per component per pixel (we only support far less);
furthermore, expn is always 0..31 for the decoder and also
sane for the encoder, so that the difference between these
two values is always in the normal range of -126..128.

Use ff_avg_pixels16_mmxext or ff_avg_pixels16_sse2
(for users with SSE2_FAST) instead.
This also allows to remove ff_avg_pixels16_mmx,

By using AnyType for resolving a strong reference we searched among all types,
not just the ones which can be the target of the reference, which in some cases
caused to find the wrong type, if the metadata set UUIDs were not unique.
UUIDs do not have to be unique if their type sets them apart, SMPTE 377M says:
> StrongRef: 'One to One’ relationship between sets and implemented in MXF
> with UUIDs. Strong References are typed which means that the definition
> identifies the kind of set which is the target of the reference.

Surprisingly the return value of add_param_definition()
(a pointer) has only been used to check for success
and not to actually access the pointee; nonsuccess
was equated with ENOMEM, although there is a non-enomem
error path in this function.
Change this by returning an int.

IAMFAudioElement and IAMFMixPresentation currently contain
pointers to independently allocated objects that are sometimes
owned by said structures and sometimes not.
More precisely, upon success the demuxer transfers ownership
of these other objects newly created AVStreamGroups, but it
keeps its pointers. iamf_read_close() therefore always resets
these pointers (because the cleanup code always treats them
as ownership pointers). This leads to memory leaks in case
iamf_read_header() without having attached all of these
objects to stream groups.
The muxer has a similar issue: It also clears these pointers
(pointing to objects owned by stream groups created by the user)
in its deinit function.
This commit fixes this memleak by explicitly adding non-ownership
pointers; this also allows to remove the code to reset the
ownership pointers.

Checking whether a pointer to an element of an array is NULL
makes no sense, as the pointer addition involved in getting
the address would be undefined behaviour already if the array
were NULL.
In this case the array allocation has already been checked
a few lines before.

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).
