Remove expired webkit-gtk2 and webkit-gtk3 ports.

Bump graphics/variety deprecation date, there is a patch for a update which
uses webkit2-gtk3 in ports/236180 but I had issues that I could't fix.

www/hotot: remove QT4 option (Qt4 deprecation)

Cleanup net-im after KDE4 removal.

 - hotot drops option KDE4

Mark QT4 ports/functionality for removal on 2019-03-15

While here, chase some KDE4 ports and functionality, these are scheduled for
removal on 2018-12-31. Change the default option/flavor to QT5 where applicable
or use alternative toolkits like GTK.

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

Convert Python ports to FLAVORS.

  Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the

Remove libintl.so.9 compatibility link that was added in r374303 to

Replace Mk/bsd.kde4.mk by Mk/Uses/kde.mk in preparation for KDE Frameworks and
Plasma5 ports

At the moment KDE ports use bsd.kde4.mk to handle their dependencies. When
working on the ports for KDE Frameworks and Plasma5 it seemed to be more
reasonable to create a new kde.mk instead of adding an bsd.kde5.mk.

The kde.mk in this review is a stripped down version of the one we are using in
the KDE Test repositories plasma5 branch [1] to only contain the parts relevant
to the current KDE4 ports in the portstree [2].

Changes to the KDE Ports needed by this:
