by using unintern rather than fmakunbound for redefined generic functions.

TODO: get load-system upgrade to work on CMUCL

Make logical pathname test work on disjoint files, for now.
Fix test-upgrade wrt recent package tweak in testing.

The issue fixed is that most Lisps don't like
*default-pathname-defaults* being a logical-pathname.
Added a test for logical-pathname functionality;
it all works on CCL, and works better on other Lisps after the fix,
but there are still logical-pathname issues on SBCL, CLISP and more.
Also, a package cleanup of our test suite.

When specifying a function as output-translation,
we accept either (:function symbol) or
(:function (lambda (pathname absolute-source) ...)
The second case wasn't properly handled.
Minimal testing included.
спасибо Сергей.

and add more extensions to clean in the Makefile.

they break the r-i contract and mess up with asdf-dependency-grovel.

We should probably refactor some more later... smells like cl-launch...

break things differently, giving user more control when things break.
Document somewhat the mess that is asdf:run-shell-command, and
recommend xcvb-driver:run-program/process-output-stream as a replacement.
Also, rename some testing targets in the Makefile, update testing status.
Finally, hush cmucl.

Use probe-file for probe-file* in LispWorks.

Make ABCL's jar translation happier with
the recent compile-file-pathname* change for Stelian by redoing cfp myself.

Make truenamize work when the merged pathname is relative.
Makes it happier when e.g. the *default-pathname-defaults* is #p"",
which is the case notably on CCL.

Try and fail to support GCL 2.6 and have 2.7 fail less;
too many bugs, in CONDITIONs, PATHNAMEs, and more,
plus compiler bug that breaks coerce-pathname.

Add doc compilation to release tests!

Recognize more architectures (for e.g. sbcl).
Fixes for cl-source-file.lsp (see previous commits by rpg).

* remove -k ${keyid} from git-buildpackage, instead inserted in ~/.devscripts:
	DEBSIGN_KEYID=4D822AA2
* remove user from ssh specifications. If local and remote users differ,
  you HAVE to have an entry in your ~/.ssh/config like:
	Host common-lisp.net
	  User frideau

Also, update testing infrastructure to work with latest xcl from git.

Also, use coerce-pathname in asdf-ecl and deprecate merge-component-name-type.

Cosmetic changes and an assertion.

Thanks to Douglas Crosher for his URL tests!
