Make sure we (re)initialize-asdf at some early point: things may have changed after image-dump.

No more bootstrapped-install with cl-launch using xcvb-built image.

Fix tests with SBCL, too.
Remove obsolete setup.lisp for good. We are in an asdf 2 world!

Also, fix Makefile.release on a Mac.

* Use define-command to define and register a command
* Introduce the notion of workspace to store intermediate and target files.
* Update Makefiles for new intended output paths

Declare more available git repositories for XCVB ports.
Update TODO/DONE.

Fix the same bug wrt loop on CLISP, in another function.
Be more violent in resetting release dependencies directories.
Fix make-release-tarball (double oops).
Export getcwd, chdir, with-current-directory from the driver.
Tweak logging, so it works when verbosity is uninitialized.

Move fake-release-directory to Lisp.
Fix enough-namestring in Makefile.

Update TODO vs DONE. Update README wrt dependencies.
Remove sbcl compiler note in driver.

  and other types of related errors.
+ Changed all externals to be :asdf instead of :build.
+ tweak dependencies

allows full bootstrap of XCVB, including ironclad.
Disable nemk self-build from tests,
as there is no ASDF equivalent to :around-compile.
Also, fix a2x wrt latest ASDF's find-system and reuse of component objects.

* extract fasl type from target:
 at least lispworks depends on pathname type and its fasl type varies!
* rucksack not available on clisp (and needed fixes; see our xcvb repo of it)
* accept compile-file failure semantics of clisp
* suppress duplicate entries for a directory in the source-registry:
 The first one wins, with its recurse and exclude flags.
* fix hello and test/runme
* fix various option parsing mistakes

Also, now that we're importing symbols from ASDF,
avoid redefining them due to a conflict. Oops.

Try to improve release.

Unrot release and test scripts.
Tested: XCCL=stccl make test LISP=ccl
