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.

Approved by:		portmgr (tcberner)

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.

devel: remove 'Created by' lines

devel/gn: Drop -T from flags passed to ar

Remove -T flag from arguments passed to ar, because of planned -T flag
removal from ar in base and misusing. For now, switch to OpenBSD's build
template. The only difference with previously used Linux's build
template is this -T switch. NetBSD still use Linux's build template.

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.

Revert r504088 per jbeich.

Apparently r503780 should be sufficient to unbreak this port on
powerpc64.  (r503780 has not yet been attempted on pylon, so I did
not note the commit.)

Reported by:	jbeich

Fix hardwired assumption that FreeBSD implies clang to fix build on
GCC-based systems.

It wasn't clear to me how to pass environment variables to build/gen.py,
so this change seemed more straightforward.

Changelog:

Minor fixes to tracing

The chrome://tracing expects the timestamp to be in microseconds, but
it had been stored in the TraceItem in nanoseconds, so this fixes it.

Also adds quotes around the thread_id, since on Mac it is written in hex
format and so the JSON parser doesn't recognize it.

Finally, adds toolchain information to the import traces.
