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.

Upgrade all CloudABI components to their latest upstream versions.

This release of CloudABI includes some minor tweaks to improve support
for Rust, including some changes that should keep the ABI more robust
going forward. In addition to that, there are some tiny fixes for Linux,
but these are not relevant for FreeBSD.

Bump CloudABI to v0.18.

Compared to the previous version, nothing installed by this port has
changed. The only changes that have happened are in the vDSO assembly
files that are only used by the FreeBSD kernel. These changes allow us
to add support for running ARMv6/7 binaries on ARM64.

devel/cloudabi and sysutils/cloudabi-utils: Upgrade to v0.17 and v0.35.

In CloudABI v0.17, we've removed some more unused bits from the polling
framework. Processes have also gained process IDs in the form of
UUIDv4s, which means they should never recycle and are globally unique.

cloudabi-utils has been patched to catch up with the ABI changes. While
there, some cleanups/bugfixes have been made to the emulator.

Update CloudABI related packages to the latest upstream versions.

We're currently working towards redesigning the entire polling/event
handling subsystem of CloudABI. This release of the CloudABI definitions
includes the first cut of changes in that area.

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 cloudabi and cloudabi-utils to the latest upstream versions.

This release of the CloudABI definitions contains some cleanups, such as
the removal of socket addresses. Though structures like sockaddr are
still defined by the C library, this information is no longer exposed by
runtimes. The reasoning being that additional services for CloudABI,
such as Flower, are going to facilitate this in the future:

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

This release includes various changes to the userspace emulator in the
area of networking. POSIX conformance of sendmsg()/recvmsg() has been
improved. File descriptor passing is now supported.

Upgrade CloudABI packages to the latest upstream versions.

Upgrade CloudABI headers and utilities to the latest upstream versions.

This release contains no changes to the actual ABI itself, but performs
some renaming of system call argument names and structure members to
make them more uniform. Ranges (pointer + length) pairs now have
automatically inferred names.

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

The most important change in these releases is that these versions now
provide very rudamentary support for i386.

Update the CloudABI definitions to version 0.7.

This version removes the native system call wrappers (the functions that
use "syscall" to invoke a system call). The reason for this is that this
will no longer be covered by the specification. Instead, userspace
processes must use the vDSO to invoke system calls.

Upgrade cloudabi-utils to the latest version.

The latest version of cloudabi-run now includes an emulator for running
CloudABI executables. Though this emulator has been primarily developed
for Mac OS X, it also works reasonably well on FreeBSD. This means that
FreeBSD users can now experiment with CloudABI even on FreeBSD <11.

The new version of cloudabi-utils now depends on an additional package,
simply called cloudabi. This package installs a set of headers that
describe the actual binary interface that programs can use.
