sysutils/fsearch: update the port to patch release 0.1.3

- Fix unresponsive column headers when an overlay is shown
  (e.g. when no results are found)
- Fix restoring of column widths from the previous session

sysutils/fsearch: unbreak fetching of the upstream patches

Once again, GitHub had changed the generated metadata slightly,
in the following lines (all of them):

  -index ca5a270..9972426 100644
  +index ca5a2703..99724260 100644

While here, add couple of missing Oxford commas, drop the plus
from the GTK name (since February 2019), and reword the port
description a bit.

sysutils/fsearch: update the port to the latest patch release 0.1.2

Switch away from using g_utf8_collate_key_for_filename() for version
sorting because it's way too slow.  For comparison, sorting 3 million
files by name takes less than a second (~850ms) with strverscmp() but
more than a minute (~95s) with g_utf8_collate_key_for_filename().

So it's roughly a hundred times slower.  Instead, pull strverscmp()
implementation directly from the GNU library sources.

Remove # $FreeBSD$ from Makefiles.

Report correct version in the About dialog.

- Update to the fourth beta version
- Shorten the COMMENT line
- Point WWW line to a working website

sysutils: Add missing USES={gnome,mate,php}

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Bump PORTREVISION for ports depending on the canonical version of GCC
defined via Mk/bsd.default-versions.mk which has moved from GCC 7.4 t
GCC 8.2 under most circumstances.

 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and

   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, as a double check, everything INDEX-11 showed depending on lang/gcc7.

Bump PORTREVISION for ports depending on the canonical version of GCC
in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.

This includes ports
 - featuring USE_GCC=yes or USE_GCC=any,
 - featuring USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and those
 - with USES=compiler specifying one of openmp, nestedfct, c11, c++0x,
   c++11-lib, c++11-lang, c++14-lang, c++17-lang, or gcc-c++11-lib.

Fix port builds for architectures which remain on gcc as the default compiler.
This will primarily help powerpc64.

For archs where clang is the default compiler, these changes will have no
effect, as the base compiler already has these capabilities (primarily, but
not exclusively, c++-11).

Tested for no-harm on amd64.

While here, pet portlint.

Mark some ports failing on powerpc64.  These ports are either new
ports, or had been recently unblocked.

While here, pet portlint.

- Update to version 0.1beta2 (still a pre-release)
- Remove patching for Linuxish #include <linux/limits.h> since it
  no longer does anything useful (the code was changed upstream)
- Use dedicated pkg-plist file now that it is long enough
