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

Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it.  Bump PORTREVISION on their dependent
ports except the ones that depend on these:

audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt

In these cases the same trick as in the recent gettext update is used.

Update the default version of GCC in the Ports Collection from GCC 4.7.4
to GCC 4.8.3.

Part II, Bump PORTREVISIONs.

audio/sdl_sound:
- USES=libtool.
- Strip library.
- Replace patch+reinplace with a single reinplace.
- Remove a patch so we use the upstream library name again.  Bump
  PORTREVISION on all dependent ports.

games/alephone:
- USES=gmake tar:bzip2.
- Remove unneeded PKG_CONFIG variable.
- Staging.
- New LIB_DEPENDS syntax.

games/asc:
- USES=libtool.

- Convert to USES=qmake (and other USES while I'm here)
- Add state support
- Convert LIB_DEPENDS to new style, adjust USE_QT4 components, etc.

Approved by:	portmgr (blanket approval)

Add NO_STAGE all over the place in preparation for the staging support (cat:
games)

Add explicit dependency on pkgconf (27 ports)

- Remove MAKE_JOBS_SAFE variable

Approved by:	portmgr (bdrewery)

Use QMAKEFLAGS, QMAKE_ARGS is not defined anywhere
