b815431126 Revert "avformat/tls_openssl: add av_assert0() for tls_shared" 
This reverts commits fd55c4b5f7
(for tls_openssl.c) and c74181a04b
(for tls_gnutls.c).

It is impossible for a pointer to a member of a structure
to be NULL: If the containing structure exists, the member
exists and can't have a NULL address; if the containing
structure does not exist, then getting a pointer to the
substructure via &c->tls_shared would already be undefined
behavior.

c9168717bf avcodec/h274: Make H274FilmGrainDatabase a shared object 
Right now, the private contexts of every decoder supporting
H.274 film grain synthesis (namely H.264, HEVC and VVC)
contain a H274FilmGrainDatabase; said structure is very large
700442B before this commit) and takes up the overwhelming
majority of said contexts: Removing it reduces sizeof(H264Context)
by 92.88%, sizeof(HEVCContext) by 97.78% and sizeof(VVCContext)
by 99.86%. This is especially important for H.264 and HEVC
when using frame-threading.

The content of said film grain database does not depend on
any input parameter; it is shareable between all its users and
could be hardcoded in the binary (but isn't, because it is so huge).

This commit adds a database with static storage duration to h274.c
and uses it instead of the elements in the private contexts above.
It is still lazily initialized as-needed; a mutex is used
for the necessary synchronization. An alternative would be to use
an AV_ONCE to initialize the whole database either in the decoders'
init function (which would be wasteful given that most videos
don't use film grain synthesis) or in ff_h274_apply_film_grain().

b5e0d9f648 fftools/opt_common: add separator line to show_filters output 
Add a separator line to show_filters() function output to maintain
consistent formatting with other show functions like show_codecs,
show_formats_devices, etc. This provides uniform formatting across
all command-line output functions for better readability and
parsing by external tools.

8d65da767b lavf: fix demuxing of FLAC files with id3v2 tags 
Due to the recent id3v2 refactor, FLAC was left out due to
earlier code not checking for id3v2 presence on FLAC.
Without the id3v2 data parsed, detection of FLAC and therefore
demuxing fails.
