Only flush state when we started parsing data, otherwise just error out.
Remove the 'fail' label to make this a bit less confusing to read.

This is used by future versions of the spec to implement metadata
compression. Given that we don't yet implement that spec, validate that
this is equal to 0 for now.

In the spec, dm_metadata_present also toggles all extension blocks, so
we need to move them inside the branch.

This is not an internal use function.

Storing the color metadata alongside the data mapping is no longer
needed, so we can simplify this array's type.

Move `vdr` into local scope and point only to the field we actually care
about.

Despite the suggestive size limits, this metadata ID has nothing to do
with the VDR metadata ID used for the data mappings. Actually, the
specification leaves them wholly unexplained, other than acknowleding
their existence. Must be some secret dolby sauce. They're not even
involved in DM metadata compression, which is handled using an entirely
separate ID.

That leaves us with a lack of anything sensible to do with these IDs.
Since we unfortunately only expose one `dm_metadata_id` field to the
user, just ensure that they match; which appears to always be the case
in practice. If somebody ever hits this error, I would really much
rather like to see the triggering file.

When this is 0, the metadata is explicitly inferred to stated default
values from the spec, rather than inferred from the previous frame's
values.

Likewise, when encoding, instead of checking if the value changed since
the last frame, we need to check if it differs from the default.

According to the spec, missing previous VDR RPU IDs do not constitute an
error, but we should instead fallback first to VDR RPU with ID 0, and
failing that, synthesize "neutral" metadata.

That's nontrivial though as the resulting metadata will be dependent on
other properties of the RPU, and this case is not hit in practice so
I'll defer it to a rainy day.

This is specified to be in the range -1 to 4095, apparently the only
extension level with such a restriction.

The boxes are a mix of things documented by Apple in some PDFs, their
API docs, and reverse engineering. Ideally we will have a real spec
one day.

As of mbedTLS 3.6.0 TLSv1.3 is enabled by default and certificate verification
is now mandatory. Our default configuration does not do verification, so
downgrade to 1.2 in these situations to avoid breaking it.

The default timer register pmccntr_el0 usually requires enabling
access with e.g. a kernel module (while it is accessible by
default on Windows). On Linux, the default for checkasm benchmarks
is to use perf (if suitable headers are available) though.

On macOS, using cntvct_el0 gives measurements with the same
magnitude as mach_absolute_time (which is used currently), but
possibly with a little less overhead/noise.

The SEI handling of libx265 is buggy and can easily lead
to memory corruption: It reuses certain buffers, but when
reusing them it presumes that it is enough for these buffers
to exist and does not check whether they are actually large
enough to hold what is intended to be stored in them.*

Our users are exposed to this because forwarding A53 CC data
is enabled by default. Change this to make it disabled
by default.

"Fixes" tickets #10411, #11052 and (presumably) #10906.
