Passing an uninitialized variable as argument to a function is
undefined behaviour (UB). The compiler can assume that UB does not
happen.
Hence, the compiler can assume that the variables are never
uninitialized when passed as argument, which means that the codepaths
that initializes them must be taken.
In ff_seek_frame_binary, this means that the compiler can assume
that the codepaths that initialize pos_min and pos_max are taken,
which means that the conditions "if (sti->index_entries)" and
"if (index >= 0)" can be optimized out.
Current Clang git versions (upcoming Clang 14) enabled an optimization
that does this, which broke the current version of this function
(which intentionally left the variables uninitialized, but silencing
warnings about being uninitialized). See [1] for discussion on
the matter.

Texinfo 7.0 produces quite different HTML to Texinfo 6.8. Without
this change, enumerated option flags (i.e. Possible values of x
are...) render as white text on a white background with Texinfo 7.0
and are unreadable. This change removes a style for the selector
`.table .table` which causes the background to turn white for these
elements. As far as I can tell, it is not actually used anywhere in
files generated by Texinfo 6.8.

Resolves trac ticket #10636 (http://trac.ffmpeg.org/ticket/10636).
Texinfo 7.0, released in November 2022, changed the names of various
functions. Compiling docs with Texinfo 7.0 resulted in warnings and
improperly formatted documentation. More old names appear to have
been removed in Texinfo 7.1, released October 2023, which causes docs
compilation to fail.
This commit addresses the issue by adding logic to switch between the old
and new function names depending on the Texinfo version. Texinfo 6.8
produces identical documentation before and after the patch.

Since texinfo 6.8, there's no longer an INLINE_CONTENTS variable.
makeinfo: warning: set_from_init_file: unknown variable INLINE_CONTENTS
texinfo commit 62a6adfb33b006e187483779974bbd45f0f782b1 replaced
INLINE_CONTENTS with OUTPUT_CONTENTS_LOCATION.
texinfo commit 41f8ed4eb42bf6daa7df7007afd946875597452d replaced
OUTPUT_CONTENTS_LOCATION with CONTENTS_OUTPUT_LOCATION.
With texinfo 6.8 and above, the same as INLINE_CONTENTS=1 could be
achieved by CONTENTS_OUTPUT_LOCATION=inline.

Since texinfo commit 6a5ceab6a48a4f052baad9f3474d741428409fd7, the
formatting functions, in particular begin_file, program_string and
end_file, are prefixed with format_, i.e. format_begin_file, etc.
This patch fixes building the documentation when texinfo 6.8, or
above, is used:
Unknown formatting type begin_file
at /usr/bin/makeinfo line 415.
Unknown formatting type program_string
at /usr/bin/makeinfo line 415.
Unknown formatting type end_file
at /usr/bin/makeinfo line 415.

The 1000 did result in the appearance of a never ending reload loop
The RFC mandates that "If the client reloads a Playlist file and finds that it has not
changed, then it MUST wait for a period of one-half the target
duration before retrying." and if it has changed
"the client MUST wait for at least the target duration before attempting to reload the
Playlist file again"
Trying to reload 3 times seems a better default than 1000 given these
durations
