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.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

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.

Fix Qt5 symbol version scripts to put the catch-all clause first.  When
a symbol matches multiple clauses the last one takes precedence.  If the
catch-all is last it captures everything.  In the case of Qt5 libraries
this caused all symbols to have a Qt_5 label while some should have
Qt_5_PRIVATE_API.  This only affects lld because GNU ld always gives the
catch-all lowest priority.

Older versions of Qt5Webengine exported some memory allocation symbols from
the bundled Chromium.  Version 5.9 stopped exporting these [1] but the
symbols were kept as weak wrappers for the standard allocation functions to
maintain binary compatibility. [2][3]  The problem is that the call to the
standard function in these weak wrappers is only resolved to the standard
function if there's a call to this standard function in other parts of
Qt5Webengine, because only then is there a non-weak symbol that takes
precedence over the weak one.  If there's no such non-weak symbol the call

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

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

Update to 3.5.0

        * bugfix: fixing code that resets tone queue on flushing.  A bug
        was found on FreeBSD: after pressing Ctrl+C, application that
        wanted to stop and delete generator as part of SIGINT handling
        procedure, got stuck in cw_tq_flush_internal() function, waiting
        for tone queue to go idle. This never happened. Resetting all tone
        queue state variables in flush function ensures that the function
        completes and returns, and that client application can exit.

        * xcwcp: the application souce code files are now ported to
        Qt5. Build system files have been modified to use Qt5 to build
        xcwcp.
        Discovery and adding -fPIC to compiler flags for xcwcp is right
        now very naive, perhaps that will have to be improved in the
        future.

New port comms/xcwcp
Sub-port of comms/unixcw

Previously, this was a build-time option, but the primary use of
comms/unixcw is to provide libcw.so (and it's a dependency of
comms/cwdaemon).

Since comms/cwdaemon is not a GUI program, it doesn't make sense to enable
the GUI by default, which would mean pkg users couldn't install this
program.  By splitting it into a sub-port, it's now available via pkg
and more obviously present when earching ports.
