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.

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.

Upgrade cloudabi-utils and related packages to the latest version.

Now that we have ARPC, Flower and yaml2argdata packaged, we can conclude
this series of commits by upgrading cloudabi-utils to the latest
upstream version again. This version of cloudabi-utils now has
integrated support for starting sandboxed processes that perform network
communication using Flower.

As cloudabi-utils has partially been rewritten in C++, drop the
dependency on libyaml. We now make use of yaml-cpp. Also apply some
minor cleanups (e.g., use DISTVERISON as opposed to PORTVERSION).

Upgrade Argdata to version 0.6.

In 0.5, the C++ bindings were broken on non-CloudABI systems. This went
by unnoticed, as we didn't use the C++ bindings on those systems yet.
Now that I'm preparing the import of CloudABI's networking daemon,
Flower, into the Ports tree, this is becoming problematic.

Update argdata to v0.5.

It turns out that version 0.4 introduced a regression in the
serialization code, where serializing without remapping file descriptors
caused the resulting file descriptor nodes to become invalid.

While there, add LICENSE_FILE. Suggested by xmj.

Upgrade argdata and cloudabi-utils to the latest upstream versions.

Version 0.3 of argdata includes an all new reader/writer API that allows
you to stream argdata objects into files, pipes and sockets. Version 0.4
reworks the iterator API to make it easier/safer to duplicate iterators.

Version 0.4 of argdata now depends on max_align_t. This type definition
is not available on older versions of FreeBSD. Add a local patch to use
a locally defined structure instead. This patch can be removed once we
only support versions that do provide this type.

Version 0.25 of cloudabi-utils catches up with the argdata iterator API
changes.

Upgrade argdata to version 0.2.

This release includes improvements to how the map/sequence iterator API
works. When using iterators, the object from which the iterator was
extracted can now go out of scope, without rendering the iterator
useless. This makes it a lot easier to traverse the tree at multiple
depths without needing to keep many iterators allocated.

Add Argdata.

The existing cloudabi-utils package has a copy of a library called
Argdata integrated. Future versions of cloudabi-utils will no longer
ship with it, as Argdata can be used independently of CloudABI.

This change introduces a new devel/argdata port, which can be used by
future versions of cloudabi-utils.
