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.

databases: remove 'Created by' lines

Convert to UCL & cleanup pkg-message (categories d)

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.

Release
notes:	https://github.com/powa-team/powa-archivist/blob/REL_3_2_0/CHANGELOG.md
		https://github.com/powa-team/pg_qualstats/blob/1.0.6/CHANGELOG
		https://github.com/powa-team/pg_stat_kcache/blob/REL2_1_1/CHANGELOG.md

Workaround the following problem on aarch64 by setting LLD_UNSAFE=yes:

  cc: error: invalid linker name in argument '-fuse-ld=bfd'

Neither emaste nor I can figure out exactly where the offending stanza is
coming in.  It will take someone with more knowledge of gmake debug flags,
and possibly the src build infrastructure, to figure it out.

While here, pet portlint.

Update to 2.0.3

Add PG 9.6 compatibility

Fix issues in shared memory estimation, which could prevent starting postgres
or reduce the amount of possible locks (thanks to Jean-Sebastien BACQ for the
report)

Add hint of possible reasons pgss.max could not be retrieved, which could
prevent starting postgres

Make portlint happy

Github cleanup.

- Use the version tag instead of commit hash when they're the same.
- Remove unnneeded variables.
- Simplify go- ports when possible.
- Various fixes.

Add pg_stat_kcache module

Gathers statistics about real reads and writes done by the filesystem layer. It
is provided in the form of an extension for PostgreSQL >= 9.4., and requires
pg_stat_statements extension to be installed. PostgreSQL 9.4 or more is
required as previous version of provided pg_stat_statements didn't expose the
queryid field.
