driver: Be more robust when borking or otherwise dying.
TODO: ABCL fork hints.

into the encodings feature. utf-8 is the default encoding and use :default
at your own risk. Anything else gets delegated to asdf-encodings.

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.

This allows the examples to be created without having to install
an XCVB. The primary implementation is in bootstrap.lisp and
additional code in driver.lisp.
+ The created XCVB is made with one of the supported lisp
implementations even though the enclosing lisp invocation might
not be.
+ Refactored lisp-invocation into its own package.
+ The cache-description file contains notes about how the cache
should function. The cache is both the multi-user cache as in
distcc, ccache, etc, but also the user specific workspace for
where to dump fasl files and whatnot.

* 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

as I was tired of completion conflicts with driver.lisp.

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 more release code from Makefile to CL.
Fix shell-tokens-to-Makefile on CLISP (CLISP bug in loop, or my misreading the spec?)
Fix some tests, make them more verbose.
Driver: Fix native-namestring on SCL; fix issues on CLISP:
Setting the *source-file-types* and *compiled-file-types* to nil
was preventing (require "linux") from working(!).

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

* get rid of no-asdf
* remove shell stuff from string-escape (moved to driver)
* fixed comments in lisp-invocation.lisp to be more correct.
