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

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

Reassign makc's ports back to the pool.

See "Maintainer Reset" in
https://www.freebsd.org/portmgr/policies_contributors.html. makc's last commit
was in March 31st (r412218), and his ports have been timing out since at least
July (r418155).

I also emailed him 2 weeks ago and have received no response so far.

Convert my ports to new options helpers

Fix LIB_DEPENDS

Cleanup plist

net-im/psimedia:
- add upstream patches to fix build with modern gcc, glib, and make -j
- add explicit dependence on audio/speex
- convert WITH_DEBUG to option
- convert to USES=tar:bzip2

- Support staging
- Use new LIB_DEPENDS syntax
- Use options helpers
- Convert to USES
- Minor changes/fixes

Add NO_STAGE all over the place in preparation for the staging support (cat:
net-im)

Add an explicit dependency on pkgconf

* Update the glib to 2.34.3 and gtk20 to 2.24.17 and gtk30 to 3.6.4 which
  are the latest stable releases.
* Update vala to the newest stable release 0.18.1, also update a few ports
  in the gtk/gnome stack.
* The c++ bindings ports for glib, atk, gconf, etc, have now USE_GNOME toggles.
* Remove pkg-config run depends from glib20 and freetype2. This doesn't
  eliminate pkg-config run dependency completely, a second phase is needed
  and is planned.
* Support for .:run. and .:build. for USE_GNOME components was added.
  Currently only libxml2 and libxslt support this mechanism.
* Updates of the telepathy stack and empathy.
* Trim makefile headers, convert ports to new options, trim off library
  versions for some ports.
* Fix other ports so they build with the new glib version.

Thanks to miwi and crees for helping out with some exp-runs.
