Subject: [PATCH 01/17] avcodec/vlc: Merge VLCElem and RL_VLC_ELEM
It will simplify creating RL-VLCs (which until now used
a stack-based VLC as temporary buffer).
Notice that there would be another option to merge them, namely:
struct VLCElem {
union {
VLCBaseType sym;
int16_t level;
};
int8_t len;
uint8_t run;
};
The main difference to the current patch is that this would change
the type of the length field of VLCElem to int8_t from int16_t.
It turns out that that this would entail additional sign extensions
on ppc, see https://godbolt.org/z/behWYEYE7. I have therefore refrained
from doing so, although it would make the patch simpler.

Subject: [PATCH 04/17] 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.

Subject: [PATCH 07/17] avcodec/hqxvlc: Make cbp_vlc static
This is trivial as well as beneficial because frame threads
now use the same table, saving cache/memory.

Subject: [PATCH 09/17] avcodec/hqxvlc: Make dc9, dc10 VLC tables static
It allows to share them between frame threads.
dc11 can unfortunately not be made static without increasing
LOCALBUF_ELEMS in vlc.c.

Subject: [PATCH 11/17] avcodec/hqx: Don't zero in small chunks, don't zero
twice
Up until now, decode_block() zeroed every block (of 128 bytes)
before decoding a block; yet this is suboptimal for all modes,
because all modes need to reset all the blocks they use anyway
and so it should be done in one go for all blocks.
For the alpha modes (where blocks need not be coded) all blocks
are zeroed initially anyway, because decode_block() might not
be doing it, so zeroing there again for the coded blocks is
a waste.

Subject: [PATCH 16/17] avcodec/qdm2, vorbisdec: Use compile-time const
max_depth in get_vlc2
It makes no sense to try to be exact with max depth
in get_vlc2(): It will mean that the compiler emits code
for all three stages of parsing and runtime checks for
whether max_depth is big enough to parse the next stage
when a not yet complete code has been encountered.

Subject: [PATCH 17/17] avcodec/qdm2: Use explicit overread checks instead of
implicit ones
If there were not enough data, checksum_size would be read
as zero (due to the implicit checks of the bytestream2 API)
and run into a "data block size invalid" error. Erroring out
earlier via "not enough extradata" is better.
