- Clean up commented PORTREVISION
- Add missing USES

Remove # $FreeBSD$ from Makefiles.

Update GCC_DEFAULT from 9 to 10.

A few (mostly Fortran-based) ports need to be patched because GCC 10
is stricter.  A handful of ports need to be restricted to GCC 9 because
they fail with 10.

5 ports still fail with GCC 10.  However, seeing as this work has been
ongoing since 2020-05-24, it is simply time to make the commit and
notify the affected maintainers.

While here, pet portlint (Makevar order).

cad/calculix-ccx: Enable multithreading with spooles.

Enabling the multithreaded version of Spooles can bring some modest, but
significant, improvements of around 12% for 4 CPUs.

Also disable (again) the Taucs slover as it is causing coredumps and
requires more investigation.

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.

Related to revision 499061 bump ports with USES=fortran to have them
benefit from the improved situation where libgcc_s is only used when
absolutely necessary.

cad/calculix-ccx: Update to version 2.15.

- Update to the latest version.
  Changelog: http://www.dhondt.de/new_calc.htm

- Attempt to make the build reproducible concerning the date in the executable.

- Drop temporarily) the taucs dependency. It brings a secondary dependency
  on metis4 which we are not packaging. We will bring taucs back when it
  depends on metis5

- Pet portlint.

Bump PORTREVISION for ports depending on the canonical version of GCC

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,

Detailed maintainer log:

cad/calculix: Split the ccx analyzer out of the main port.

CalculiX has alwasy been comoposed of two independent packages: ccx and
cgx. Ccx, the main tool for doing FEA, depends on fortran and currently
has to be built with GCC. Cgx, on the other hand, uses OpenGL and the C++
libraries it depends on are built with our native clang so buuilding it
with GCC causes C++ library conflicts.

By making ccx an independent port we can better focus on the specific
requirements of each tool and avoid compiler-related conflicts. This also
helps the port work again with newer versions GCC.
