Mk/Uses: Move man to share/man for kde framework

All ports utilizing USES=kde has been tested. If there are breakage on
other parts of the tree buzz me.

framework: move 'phonon4' from qt.mk to kde.mk as 'phonon'

To depend on phonon, you now need

USES=	kde:<ver>
USE_KDE=phonon

if you want to depend on the backend, also add

USE_KDE=	phonon-backend

graphics/kamerka: use phonon4 component instead of LIB_DEPENDS

devel/kf5-extra-cmake-modules: add as build dependency

- these ports previously got ecm through an unclean dependency
  (run_depend) from one of their dependencies.

audio/opus: bump consumers after update to 1.4

Mk/Uses: always use colon for build/run suffix

Most USES use a colon for build/run(/test) suffixes. Change kde.mk,
qt.mk and pyqt.mk to do the same, and update all ports using that.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

graphics/kamerka: pet stage-qa

not-KDE Applications: chase doctools

These ports, not maintained by kde@, use KDE Frameworks
and require kdoctools to build. Since that is no longer
an implicit build & run dependency, (re)introduce it
explicitly as a build-time dependency.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Add missing dependency on kinit

A handful of ports implicitetly dependet on kinit through some other port,
which in turn itself shouldn't have. In r535466 this was removed, and the
dependency on kinit now needs to be made explicit.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

graphics/kamerka: fix build with GCC-based architectures

Add USES=compiler:c++11-lang because of:
CMake Error in src/CMakeLists.txt:
  The compiler feature "cxx_decltype" is not known to CXX compiler

  "GNU"

  version 4.2.1.
