math/gnome-calculator: Update to 40.1

Remove # $FreeBSD$ from Makefiles.

Update to MPC version 1.2.0 with the following changes:
 - New functions:
   . mpc_sum
   . mpc_dot
 - Several functions are more robust with a reduced exponent range
   (for example corresponding to IEEE 754 binary formats).
 - New mpcheck tool for comparison with the native C library (which
   is not installed by default).

Bump all directly dependent ports. Do not bump those indirectly
dependent via the lang/gcc* family since their run-time dependencies
and code generated should not be affected.

Always prevent building valadoc.

The build system check for valadoc, if found in the environement then
it will be used to generate the devhelp documentation. otherwise no.
This behaviour is not optionable, so disable entirely the generation
with a patch for now.

note that in a clean environement it does not happen as valadoc is not
present.

Update to 3.38.0

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.

This update doesn't contain the glib/gtk c++ bindings which will
be done in a another update due to the requirement on c++11 and the
amount of fallout this probably will give.

GDM is still at version 3.16 due to some issues.

The FreeBSD GNOME team proudly presents GNOME 3.14 and Cinnamon 2.2.
Gnome 3.14.1 and Cinnamon 2.2.16 are supported on FreeBSD 9.3-RELEASE and up.

This commit removes the old GNOME 2 desktop, bindings and some ports that
can't be compiled. A few ports where updated to more recent versions to
allow them to compile with this update.

Apart from updating ports to newer versions

GDM is more integrated with gnome-shell now, and handles several things for
the GNOME desktop such as screen locking. If you want to use GNOME 3 via
startx, you will have to add your own lock screen/screensaver. For example
xscreensaver
can be used for sessions started without GDM.

Shell Extensions can be installed via https://extensions.gnome.org/ , we have
