Since D3D11 was introduced for QSV in FFmpeg 5.0, there is an implied
API/ABI change for user-supplied frames [1], hence update the
description for AV_PIX_FMT_QSV.

Should fix fate failures on Windowx x86 targets, where long is 32 bits.

The amount of lines printed is too high for the verbose level, and the debug
level is a better fit for their content.

Mostly consistent formatting and consistently ordering of
warnings/notes to be next to the description.
Additionally group the AV_DICT_* macros.

This is a more explicit iteration API rather than using the "magic"
av_dict_get(d, "", t, AV_DICT_IGNORE_SUFFIX) which is not really
trivial to grasp what it does when casually reading through code.

This can be achieved by moving the AVOnce out of the structure
containing the function pointers; the latter can then be made
const.
This also has the advantage of eliminating padding in the structure
(sizeof(AVOnce) is four here) and allowing the AVOnces to be put
into .bss (dependening upon the implementation).

It is possible to avoid the factors array for the power-of-two
tables for which said array is unused by using a different
structure for initialization for power-of-two tables than for
non-power-of-two-tables. This saves 3*15*16B from .data.

Up until now, av_aes_init() uses a->round_key[0].u8 + t
as dst of memcpy where it is intended for t to greater
than 16 (u8 is an uint8_t[16]); given that round_key itself
is an array, it is actually intended for the dst to be
in a latter round_key member. To do this properly,
just cast a->round_key to unsigned char*.
This fixes the srtp, aes, aes_ctr, mov-3elist-encrypted,
mov-frag-encrypted and mov-tenc-only-encrypted
FATE-tests with (Clang-)UBSan.
