Update math/eigen3 to 3.3.7

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.

Bump PORTREVISION for ports depending on the canonical version of GCC
defined via Mk/bsd.default-versions.mk which has moved from GCC 7.4 t
GCC 8.2 under most circumstances.

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, as a double check, everything INDEX-11 showed depending on lang/gcc7.

- Update astro/wcslib to 6.2

Deprecate KDE4 software, categories a-c.

The last upstream release supporting KDE4 was 10 months ago,
https://www.kde.org/announcements/announce-applications-17.08.3.php ,
and the kde@ team for FreeBSD has supported modern KDE (i.e.  KDE
Frameworks, Plasma 5 and KDE Applications) for 4 months. Give a 4
month deprecation period to allow users to switch over.

Not marked deprecated: audio/kid3-kde4, that's not ours, and it
supports Qt5 and KF5 as well despite its name.

- Update to 5.19.1

Bump PORTREVISION for ports depending on the canonical version of GCC
in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.

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,
   c++11-lib, c++11-lang, c++14-lang, c++17-lang, or gcc-c++11-lib.

Replace bsd.qt.mk by Uses/qt.mk and Uses/qt-dist.mk

From now on, ports that depend on Qt4 will have to set
	USES=		qt:4
	USE_QT=		foo bar
ports depending on Qt5 will use
	USES=		qt:5
	USE_QT=		foo bar

Bump PORTREVISIONs of all users of math/mpc that we just updated to
version 1.1.0 (via revision 464079).

Give the KDE SC4 applications ports a -kde4 suffix

In order to make room for the up-to-date version of the KDE Desktop and its
applications move the KDE Application ports based on Qt4.
