audio/liblastfm-qt5: Rename and only support Qt6

Move port origin to audio/liblastfm and only support Qt6. Qt5 support
is not required by anything currently in the ports tree.

Switch to active fork and update to latest commit.

Convert TEST option to the cmake testing framework.

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.

Approved by:		portmgr (tcberner)

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.

audio/liblastfm-qt5: Restore the patches that were originally part of
audio/liblastfm (R.I.P.) to make the library function again. It seems they
were forgotten when this was converted to a free-standing port in r495869.

MFH:		2021Q1 (runtime fix)

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.

audio/liblastfm-qt5: unbundle from audio/liblastfm (Qt4 deprecation)

* audio/liblastfm will be removed later on, prepare for it.

Approved by:	portmgr (implicit)

- Update audio/liblastfm to 1.0.9-5-g4433165 [1]
- Add audio/liblastfm-qt5 slave port which provides a Qt 5 interface [1]
- Explicitly mark UrlBuilder::mobilize() as deprecated

- Allow Qt4 and Qt5 versions to be installed concurrently
- Make sure liblastfm creates the directories it uses instead of relying
  on client apps to do so
