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.

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

  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
  current python flavor.  It can be used in dependency lines when the
  port itself is not python flavored.  For example, deskutils/calibre.

  By default, all the flavors are generated.  To only generate flavors
  for the versions in PYTHON2_DEFAULT and PYTHON3_DEFAULT, define
  BUILD_DEFAULT_PYTHON_FLAVORS in your make.conf.

  In all the ports with Python dependencies, the *_DEPENDS entries MUST
  end with the flavor so that the framework knows which to build/use.
  This is done by appending '@${PY_FLAVOR}' after the origin (or
  @${FLAVOR} if in a Python module with Python flavors, as the content
  will be the same).  For example:

    RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

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:

Replace USE_KDE4 by USE_KDE [3]
Add USES=kde:4 [4]
[1] http://src.mouf.net/area51/view/branches/plasma5/KDE/Mk/Uses/kde.mk
[2] The version in the plasma5 branch also handles frameworks/plasma5 and
    handles MASTER_SITES via a KDE_DIST variable similar to bsd.qt.mk for Qt
    Ports -- I chose to leave this out for now, as the diff is already large
    enough.
[3] I chose USE_KDE instead of USE_KDE4, USE_KDE5, USE_KDEX as the version we
    want is already specified as argument to kde:<arg>
[4] For KDE Frameworks and Plasma5 ports this would be kde:5
