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

Fix qt4 ports on armv6.

Due to a misspelling in GCC [1] (probably) the check for the ARMv6KZ platform
used ARM_ARCH_6ZK instead of ARM_ARCH_6KZ.

Update Qt5 to 5.7.1, and unify the Qt4 and Qt5 ports some more

* Update Qt5 to 5.7.1
* Move Qt4 binaries to lib/qt4/bin
* Move Qt5 libraries to lib/qt5/lib
  By moving the libraries we should finally be able to get rid of the inplace
  upgrade bug (see ports bugs 194088, 195105 and 198720):  when Qt5's libraries
  were lying in /usr/local/lib, which would often get added by pkgconfig to the
  linker paths via dependencies, the already installed libraries were linked
  against, instead of the ones that were being built. This forced us to make
  sure, that -L${WRKSRC}/lib was always coming before -L/usr/local/lib in the
  linker flags. With this change this should no longer be the case.
* Rename some ports to match the rest (foo-qtX -> qtX-foo)
* Depend on new port misc/qtchooser [see UPDATING & CHANGES]

There are several new Qt5 ports which all have been created by Marie Loise
Nolden
<nolden@kde.org>. Thanks again.

Update the Qt4 ports to 4.8.7.

According to upstream, this is the last planned Qt4 release.
A list of changes since 4.8.6 can be found here:
<http://download.qt.io/official_releases/qt/4.8/4.8.7/changes-4.8.7>

Porting notes and changes:
- Remove several patches that have been upstreamed.
- Make Uses/qmake.mk pass the contents of LIBS to the qmake environment. [1]
- Repurpose devel/qt4/files/extrapatch-src-corelib-global-qglobal.h now the
  original patch is part of the release (curiously enough, the original
  patch was never actually used, as the ?= assignment in r362837 after
  r362770 was never possible).

  This works around the way compiler support for C++11 features is detected

Remove @dirrm and @dirrmtry entries from the Qt ports.

Remove libtool .la files from all Qt ports

In preparation for Qt 5 ports:

Mk/Uses/qmake.mk:
- Add support for out-of-source builds
- Add support for Qt 5 ports
- Respect WITH_DEBUG

Mk/bsd.qt.mk:
- Massive rework for Qt 5 ports
- Remove '-phonon' from global configure args, thus allow qt4-designer and
  qt4-qtconfig to be built without Phonon support [1]

devel/qmake4:
- Improve mkspecs for gcc (mainly sync with linux version) and clang
