filesystems: add new category for file systems and related utilities

The filesystems category houses file systems and file system utilities.
It is added mainly to turn the sysutils/fusefs-* pseudo-category into
a proper one, but is also useful for the sundry of other file systems
related ports found in the tree.

Ports that seem like they belong there are moved to the new category.
Two ports, sysutils/fusefs-funionfs and sysutils/fusefs-fusepak are
not moved as they currently don't fetch and don't have TIMESTAMP set
in their distinfo, but that is required to be able to push a rename
of the port by the pre-receive hook.

sysutils/kio-fuse: Update to 5.1.0

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.

Document in CHANGES.

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.

Update sysutils/kio-fuse to latest upstream release

There's no notes for this release, but a handful of bugfix commits
in the repository and an announcement can be found on the
kde-announce-apps mailing list.

Our local patches have been submitted upstream as a MR, hopefully
they will become unnecessary in a future release.

Fix up -descr and -message for sysutils/kio-fuse

Update sysutils/kio-fuse to latest upstream release

kio-fuse does some FUSE magic to pass remote KIO paths (e.g. when
browsing SMB or ftp from Dolphin) to non-KIO-aware applications
(e.g. opening a text file with vi). This 5.0.0 release has been
out for a while and is functionally equivalent to the previous
one; now, however, there's real release tarballs and everything.

Existing patches have been re-built for this release and then
submitted upstream, which is why they now have git-hashes.

Update sysutils/kio-fuse to latest upstream

These are progressive betas, basically; this release drops Boost from
the dependencies.

sysutils/kio-fuse: Fix build

While boost is an implicit dependency, make it explicit for
the sake of the patch added in r525170. Also, on amd64 &c,
wherever Boost headers end up isn't automatically in the
C++ header search path, so find Boost in CMake and use those
headers.

sysutils/kio-fuse: fix build on GCC architectures

As usual, C++11 compiler is necessary.

Another issue is that ENODATA is not defined on GCC systems. Include
boost/cerrno.hpp (boost is already indirect dependency) to have this macro.

[New port] sysutils/kio-fuse: FUSE Interface for KIO

KioFuse allows you to mount remote directories into the root hierarchy of your
local file system, thereby exposing KDE's advanced access capabilities (SSH,
SAMBA/Windows, FTP, TAR/GZip/BZip2, WebDav, etc) to POSIX-compliant
applications such as Firefox, OpenOffice, GNOME apps, shell utilities and more.

KioFuse works by acting as a bridge between KDE's KIO filesystem design and
FUSE.
