cleanup: Remove expired ports:

2022-09-30 devel/flang: Very outdated and unsupported upstream, current version
in tree is several years old and upstream is still active

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/flang: Deprecate and set expiration date to 2022-09-30

Current version is very outdated and unsupported upstream
Upstream is working to improve Flang compiler included in LLVM

devel/flang: update to the latest upstream snapshot

OpenMP now works in my tests.

Factor out hardcoding of the string "clang<version".  When doing the
work to identify stale versions of clang tree-wide, these instances
cause extra work.

Refactor this usage into LLVM_VER.

Note: this refactoring causes portlint to complain but IMHO this
annoyance is worth tolerating to help ease maintainability.

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.

devel/flang: Attempt to fix TESTS option

In r479159 the TESTS option was incorrectly switched to options
helpers.  Options helpers are ineffective when set after
bsd.port.options.mk and it should have used the CMAKE_BOOL helper.

Change cmake default behaviour to outsource.

Ports that build out of source now simply can use "USES=cmake"
instead of "USES=cmake:outsource". Ports that fail to build
out of source now need to specify "USES=cmake:insource".

I tried to only set insource where explictely needed.

devel/flang[-clang]: remove wrapper script dependency.

Patch flang-clang directly to link the required libraries and include the proper
library directories. Hence, the need of the wrapper script (and it's non-optimal
behavior) vanishes.

While there, mark flang-clang broken on 10. Its LLVM6 base is not supported
there and due to libpgmath only working on 12+, there is no need for it
anyways.

devel/flang[-clang]: update to later snapshots

This introduces flang-driver, a clang6-derived driver / companion compiler, and
uses math/libpgmath as the math library backend. Notably, the latter currently
limits us to 12-CURRENT.

Patches are a combination of carry-over and adapted OpenBSD ones.

While there, pet portlint.

Make ninja opt-out in cmake.mk

Using ninja instead of make (1) can lead to significant speed ups while
building.
Therefore switch from having the ninja generator opt-in to having it opt-out.

Previously cmake-ports that wanted to use ninja could set
    CMAKE_NINJA=yes
now, ports that do not work with ninja can set
    cmake:<existing args>,noninja
Note, that needing this should be an exception and most often points to a broken
cmake of the port.

The ports using cmake were modified
* removed USES=gmake, if ninja is used
* removed MAKE_ARGS, if ninja is used
* added the cmake-argument noninja if necessary

devel/flang: update to latest github revision to chase their work in progress.
While there include two suggestions by Steve Kargl in the flang wrapper script
(add flang's include directory by default, add libompstub by default). Add a
TESTS option that enables flang's internal unit tests (request on
freebsd-fortran@). The last does not seem to be doing much in upstream yet.

There is still a problem when trying to compile statically. Also, OpenMP code
does compile w/ -fopenmp -L/usr/local/lib but does not execute in parallel yet.
