devel/p8-platform: fix build with clang 16

Since clang 16 (and gcc 11) the default C++ standard is now gnu++17.
Because devel/p8-platform's Makefile does not explicitly set its C++
standard, this leads to an error:

 
/wrkdirs/usr/ports/devel/p8-platform/work/platform-p8-platform-2.1.0.1/src/util/StringUtils.cpp:456:69:
error: no member named 'ptr_fun' in the global namespace
    str.erase(str.begin(), ::find_if(str.begin(), str.end(),
::not1(::ptr_fun(isspace_c))));
                                                                    ~~^

    str.erase(::find_if(str.rbegin(), str.rend(),

                                                         ~~^

Upstream already fixed this in
<https://github.com/Pulse-Eight/platform/commit/a7cd0d5>, via
<https://github.com/Pulse-Eight/platform/pull/45>, so apply it.

While here, pet portlint.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

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.
