Despite its name, this function is not part of the public API, as
formats.h, the header containing its declaration, is a private header.
The formats API was once public API, but that changed long ago
(b74a1da49d, the commit scheduling it to
become private, is from 2012). That avfilter_make_format64_list() was
forgotten is probably a result of the confusion resulting from the
libav-ffmpeg split.

It is unused since 8cbb055760 and it
actually coincides with avfilter_make_format64_list().

Snow uses the ratecontrol module, but does not expose a way to set
the rc_eq expression. The default expression, set in the ratecontrol
module, will always be used.
Make it possible to set rc_eq by adding an AVOption to snowenc.
The option definition is mostly a copy from the mpegvideo common
options definition of rc_eq (libavcodec/mpegvideo.h), with some
minor style adjustments to be closer to the other snowenc option
initializer expressions.

Also add and update some tests.
Change the semantic a little, because for filesytem paths
symlinks complicate things.

Up until now, the TiVo demuxer parse an array of SEQ entries, yet it has
never ever made any use of them. In fact, parse_master, the function
parsing said table, only influenced the outside world in three ways: Via
an excessive amount of error message in case a certain parameter is not
what it expected; via an allocation (the aforementioned write-only
array); and by setting a certain parameter (ty->cur_chunk_pos), but that
parameter is always overwritten before it is used (it is overwritten
in get_chunk() on success and if get_chunk() fails, the error is
returned to the caller anyway). So remove the array and the function
used to parse it.

It has no bearing on structure. Determined by looking at the ASF
files from several Argonaut games:
- FX Fighter,
- Croc,
- Croc 2,
- The Emperor's New Groove, and
- Disney's Aladdin in Nasira's Revenge
The only versions that appear are 1.1, 1.2, and 2.1, and their
structure is identical.

Up until now, opening a section filter works as follows: A filter is
opened and (on success) attached to the MpegTSContext. Then a buffer for
said filter is allocated and upon success attached to the section
filter; on error, the filter is simply freed without removing it from
the MpegTSContext, leaving the latter in an inconsistent state. This
leads to use-after-frees lateron.
This commit fixes this by allocating the buffer first; the filter is
only opened if the buffer could be successfully allocated.

Because in single file by encryption mode, it cannot get the last one
block of the file, it need ff_format_io_close for get full file size,
then hlsenc can get the total size of the encryption content,
so write the content into temp file first, and get the temp file content
append the temp file content into append to single file, then hlsenc can
get the correct file/content size and offset.

X2RGB10 tested on both Intel Gen9 and AMD Polaris 11. NV12 tested on
Intel Gen9 only - since it has multiple planes, this requires GetFB2.
Also add some comments to split the list up a bit.
The most useful feature here is the ability to automatically extract the
framebuffer format and modifiers. It also makes support for multi-plane
framebuffers possible, though none are added to the format table in this
patch.
This requires libdrm 2.4.101 (from April 2020) to build, so it includes a
configure check to allow compatibility with existing distributions. Even
with libdrm support, it still won't do anything at runtime if you are
running Linux < 5.7 (before June 2020).
It leads to an assert in ff_read_packet().
