Tests: SBCL passes test-lisp and test-upgrade
Also:
* big refactoring of test infrastructure
* contrib/debug.lisp and (asdf/driver:asdf-debug) for debugging.
* remove aif and it, use the cleaner if-bind.
* backtrace support, with improvements from trivial-backtrace.
* integration of asdf-condition-control (originally from xcvb-driver)
* simplify the upgrade heuristic: always tries to upgrade once.
  The previous heuristic was too complex with too many failure cases.
  You are thus assumed to want a given version asdf
  if and only if it is in your source-registry.

I had failed to preserve the extension point cleanup-upgraded-asdf,
reusing the name the wrong way. Doing it right this time.

Found this bug during ASDF upgrade tests.
Add ecl_bytecodes to the upgrade test regimes.
Rename it from ecl-bytecodes to work with stupid Bourne shell.
Add xcl to test regime.

2.26.14: Play nicer with timestamp propagation by interning dependency to parent's outer dependencies
as something explicit.

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

* use only one package for everything: ASDF. This simplifies the upgrade a bit.
* export component-visited-p, record an index rather than a boolean.

Also
* On CLISP, only use custom:*module-provider-functions* when defined (2.49+)
* In Makefile, mrproper before debian package.
* Document that CLISP and SCL now support REQUIREing through ASDF.
* Fix mistake in run-tests that made it always use sbcl

Fix wild-modules to work nicely well with ASDF2.
Allow to pass multiple script arguments to run-tests.sh.
Tests now pass on ABCL.

Fix link in webpage (lp#614806).
Include SCL and ABCL in my testing routine.

Introduce component-operation-time as an interface for POIU to hook on.
declare ignorables, to hush warnings on ECL without alarming Allegro.
Make run-tests return proper result code, fix make test-all.
make test-all => success

as destination from output-translations, plus usage by default for jars in ABCL.

Move test results in tmp/ directory.

be more clever about recompiling asdf.lisp,
and include implementation version in output-translations.

* Fix initialize-output-translations to actually use the environment,
 map output destinations to themselves, and
 actually take a parameter as documented.
* Document same parameter for initialize-source-registry, which did take it.
* Tweak symbols between unintern and fmakunbound
 to make upgrade better on both current SBCL and ECL.
* Tweak run-tests to allow for parametrizable binaries,
 to redirect output to tmp/fasls, to output Lisp command being executed,

which one of my previous refactorings broke. (Thanks to Mark Evenson)

(found by the pathname-test in ecl)

Add janderson's pathname test script to our test suite.

Treat :unspecific specially in merge-pathnames wrt logical-pathnames, use it in split-name-type.
Add protocol to short-circuit output translation.
Some updates to the documentation manual.
Add testing support for gclcvs (though it currently fails bigtime).
Refactor run-tests to to remove need to know $fasl_ext.

Thanks to tcr for suggestions.

The eval command line argument was not correct for
Allegro CL.

* made it easier to debug tests. export DEBUG_ASDF_TEST=t
* add ECL support to tests: passes all 18 scripts, but have to ignore compile warnings.
* lots of whitespace issues, including ones that made .gitignore not work!
