    speexdec: fix framesize for ultra-wideband

This matches how the libspeex decoder is calculating frame size (except in clamp form).

Fixes #11495

    FFHWAccel: add buffer_ref argument to start_frame

This commit adds a reference to the buffer as an argument to
start_frame, and adapts all existing code.

This allows for asynchronous hardware accelerators to skip
copying packet data by referencing it.

    avcodec/hqxvlc: Avoid hardcoded RL VLC table

hqxvlc.c contains sort-of run-length VLCs in hardcoded form;
they amount to 26688 elements, taking 104KiB. These tables contain
many duplicated entries (they are partially created via a RPT_1024
macro). There are actually only 3039 different codes in all tables
combined, making this very wasteful.

This commit changes this by extracting the underlying entries
and creating a (static) RL-VLC. This only costs 3*3039 bytes
of .rodata. The resulting table needs only 15630 entries,
because our VLC init code uses smaller subtables when possible
(for an incomplete code, the negative of the length stored in
the VLC code is the number of bits the subtable uses; the hardcoded
tables uses a worst-case per table value).

Using GET_RL_VLC also gets rid of an unnecessary reload in case
a code is too long to be parsed in the first stage.

    hwcontext_vulkan: fix downloads; use the common host map function to map frame data

This commit uses the recently exported code for host mapping images back
where it was exported from.

The function also had broken download code for image downloading since its
recent refactor.
