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.

devel/sigar: build after filedesc struct change

In base revision r363214[1] we dropped the fd_lastfile field of the
filedesc struct. This breaks devel/sigar.

The applied solution was proposed by mjg@ in this[2] mail thread.

Return tj's ports to the pool after his commit bit got safekept.

Fix build after src r317061. Declare our own vmmeter on all FreeBSD versions.

Make it compilable on FreeBSD 12 after struct inpcb and struct tcpcb were
stopped being exported.

Unbreak build on head: v_cache_count was removed from struct vmmeter in
base r309017 as it was no longer used (always zero).

devel/sigar: fix build on 11-CURRENT after removal of v_cache_min/max

Update ports in the [bcd]* categories to not use GH_COMMIT.

With minor cleanups to make things simpler.

Update USE_GITHUB so it does not require GH_COMMIT.

Using this new scheme allows only setting the _tag_ or _commit hash_ in
GH_TAGNAME and not having to know the hash for a tag.  This scheme will
download a tarball that has a different checksum than before due to a changed
directory name for extraction.

The following MASTER_SITES are provided to retain the old checksum and
directory structure (that require GH_COMMIT):
  GH -> GHL
  GITHUB -> GITHUB_LEGACY

The Sigar API provides a portable interface for gathering system information
such as:

* System memory, swap, cpu, load average, uptime, loginsi
* Per-process memory, cpu, credential info, state, arguments, environment,
  open files
* File system detection and metrics
* Network interface detection, configuration info and metrics
* TCP and UDP connection tables
* Network route table

This information is available in most operating systems, but each OS has their
own way(s) providing it.  SIGAR provides developers with one API to access this
information regardless of the underlying platform.  The core API is implemented
in pure C with bindings currently implemented for Java, Perl, Ruby, Python,
Erlang, PHP and C#.
