Infrastructure for Common Lisp Ports: Overhaul

- Decouple ASDF initialization from devel/cl-asdf by creating a
  dedicated port: devel/freebsd-cl-asdf-init.
- Convert devel/cl-asdf/bsd.cl-asdf.mk to USES=cl.
- Add devel/cl-asdf-sbcl
- Update ASDF configuration:
   - Prefer newer ASDF versions, but only if the fasl is available.
   - Replace license text with an SPDX license identifier.
   - Simplify and clarify documentation.
   - Remove the assumption that ${PREFIX} is /usr/local.
   - Use uiop:getenv instead of a custom getenv function.
   - Remove asdf:output-files customization to resolve output
     translation issues.
   - Improve output translations:

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.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Remove ${PORTSDIR}/ from dependencies, Mk and categories a, b, and c.

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Remove indefinite articles from COMMENT where I'm maintainer.

Stage support

According to the Porter's Handbook (5.12.2.3.) default options must be added to
OPTIONS_DEFINE. This policy has been implemented only recently that's why we
have many ports violating this policy.

This patch adds the default options specified in the Porter's Handbook to
OPTIONS_DEFINE where they are being used. Ports maintained by
gnome@FreeBSD.org, kde@FreeBSD.org and x11@FreeBSD.org have been excluded.

Convert Makefile headers to the new format in my ports.

Bump PORTREVISION: rebuild ports that depend on devel/cl-asdf.

- Get Rid MD5 support

Add missing dependency on devel/cl-alexandria.

Add cl-babel, a charset encoding/decoding library, not unlike GNU
libiconv, but completely written in Common Lisp.
