multimedia/libmediainfo: Fix libtool

Log message:
medainfo: fix two CVEs using upstream patches

Bump PKGREVISION

Log message:
mark packages that fail with -Werror=char-subscripts

These packages are susceptible to bugs when confronted with non-ASCII
characters.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94182.

It takes some time to analyze and fix these individually, therefore they
are only marked as "needs work".

Log message:
Use public SHLIB_TYPE instead of private _OPSYS_SHLIB_TYPE.

Log message:
Update mediainfo and libmediainfo to 0.7.77

The change logs between 0.7.65 and 0.7.77 total several hundred lines, and
consists primarily of very detailed per-codec trivia.  The complete change
logs can be found in the source distribution as MediaInfo/History_CLI.txt and
MediaInfoLib/History_DLL.txt.

Pkgsrc:

  - patch-MediaInfoLib_Source_MediaInfo_Text_File__Ttml.h applied upstream.

  - pkglint a bit.

  - mediainfo appears to have done some work in avoiding bashisms, so remove
    "bash" from the tools.

  - CONFIG_SHELL doesn't need to be explicitly bash any longer.  Possibly this
    was only ever necessary because bash seems to be the only shell that was
    willing to treat a garbage shell substitution (caused by a bug in the
    configure.ac) as somehow legal.

  - ... and libmediainfo now actually builds if you accidentally on purpose
    override CONFIG_SHELL to be pdksh.

Log message:
Don't provide an empty DESCR, copy mostly from mediainfo.

Log message:
Simplify PKGNAME.
