Patrice Dumas 4d9cdf82ee doc/t2h: Support texinfo 7.1 and 7.2 pretest ...

Here is a proposed patch for portability of doc/t2h.pm for GNU Texinfo
7.1 and 7.1.90 (7.2 pretest).  I tested against 7.1 and 7.1.90 (7.2
pretest).  There is a difference in the headings compared to the website
version, maybe related to FA_ICONS not being set the same, but the
result seems correct.

I also renamed $element to $output_unit in ffmpeg_heading_command as in
new equivalent makeinfo/texi2any code the $element variable is the
$command variable in ffmpeg_heading_command, which is very confusing.  I
left as is the $command variable to have a patch easier to read, but it
could make sense to rename $command as $element later on.

The patch could also have effects with Texinfo 7.0, since some of the
changes are for that version, but that probably never show up because it
is for situations that may not exist in ffmpeg manuals (for example
@node without sectioning command), or because the code is robust to some
missing information (case of $heading_level in ffmpeg_heading_command
that was not set, as far as I can tell).
