be included there.
Also move the code to initialize the VLCs to hq_hqa.c.

they would be useless if it were different.

have been used. Unsparsing this table is especially
important given that this array lives in .data.rel.ro.

All the fields of FFVkCodecMap are either decoder-only
or encoder-only (with the latter being unused and unset for now).
Yet there is already a per-decoder struct containing
static information about these decoders, namely
VkExtensionProperties.
This commit merges the decoder-parts of FFVkCodecMap
with the VkExtensionProperties into a common structure.
Given that FFVkCodecMap is now unused, it is removed.

This is possible because the lifetime of both coincide.
Besides reducing the number of allocations this also simplifies
access to VTFramesContext as one no longer has to
go through AVHWFramesInternal.

Components and pieces are side data specific fields and there's a variable
amount of them.
They also need to be identified in some form, so print a type too.

Do not propagate the return value of avformat_write_header(),
as it contains the information whether the output had
already been initialized in avformat_init_output(),
but this is set generically; the return value of
FFOutputFormat.write_header is not documented at all
(and is currently ignored if >= 0), but it is more future-proof
to simply return 0 on success.

Doxygen eats the newline in the first comment, making it harder to read.
Join the lines and add a comma, so source and documentation are equally readable.
Doxygen only associates the second comment with cust_dec.
The comments for cust_dec and cust_tab make perfect sense without it,
so downgrade it to a non-doxygen "//" comment.
The third comment was missed by the command in the previous commit,
because it (correctly but uniquely) doesn't have a trailing comma.
