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.

devel: remove 'Created by' lines

Stage support

Add NO_STAGE all over the place in preparation for the staging support (cat:
devel part 1)

Do not try to remove DOCSDIR if built without docs

Convert Makefile headers to the new format.

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

-remove MD5

Remove redundant code and variables from the cl-* ports.

Introduce bsd.cl-asdf.mk to automate the compilation and installation
of Common Lisp libraries using the ASDF framework.

Currently it supports building FASL files on SBCL and CLISP, to
support the ports that already exist in the ports tree.

This should help bringing in more cl-* ports from the ASDF repository
without excessive code duplication.

Always use " -sf".

Cleanup whitespace, disable command echo and reduce diff between
similar code fragments.

Take over a few unmaintained ports.

For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.

New Port: Common Lisp portability package

        CLOCC Port is a wrapper library for various functions (sockets,
        shell access, etc) that are widely implemented in Common Lisp
        systems, but lack a standardized interface.

        This port depends on the previously submitted ASDF port. It installs
        the source files and an .asd file (which plays a similar role to
        a Makefile and a pkg-config script). There are other ports for each
        supported Lisp system.
