Better version mangling helpers.

Image: for compatibility with existing CL practice,
the call the entry-point *without* arguments rather than with C command line.

jyknight will be happy. Passes test, when still resolving.

also use asdf-defsystem as the name for packaging.

unless we're backward compatible.

Have one bigger lisp script to replace several shell scripts.

A system named foo/bar will be looked up in a registered file foo.asd.
This makes it possible to sensibly name several systems in a .asd file
and still have asdf find them all by name.
We now use it to not have the asdf header be part of asdf-driver.

A new generic operation build-op makes it possible to deal with
the fact that the default operation for systems need not be load-op,
yet that the end-user does not want to have to know the exact operation
for each of the system he uses.

ensure-pathname has been improved again, and its clients tweaked.

remove-keys was made more sensible by using EQL rather than STRING-EQUAL.

:version need not take the first form in a file, but can take
a path to a subform. This makes it possible to get the exact subform
in a Lisp source file that has the string.
See SUB-OBJECT for how these paths work.

Cleanup of the semantics of ENSURE-FUNCTION on CONSes: use APPLY, not EVAL.

Move things around and rename functions to improve backward compatibility.
The driver now has its own backward-compatibility file.

Settle on "restore-image" and "dump-image" for our API names.
Unbreak match-condition-p and move it to utility,
give static scoping to the generic muffler,
rename the compiler and loader mufflers.
Fix with-input.
Remove crud from script-support.

Package cleanup: every file in asdf itself now :use's asdf/driver asdf/upgrade.
Test script fix:
Allegro, like ECL *really* hates that we close *standard-input*,
so stop trying at all.
Tweak some utilities and debug utilities.

Also, improve the bump-version script.

Much cleanup in image support and hooks.
More package hacking.
New feature for :version: `(:read-file-from ,path) - thanks to Stelian Ionescu.
The driver now homesteads the package nickname d.
Rename-package it away if you don't like it.

New pathname functions to work around more logical-pathname issues.
See discussion with rpgoldman on asdf-devel, and see CCL ticket:953.
Also, tweak build to reflect recent refactoring of asdf.
WIP of define-package work needed for clean upgrade (still broken).

TODO: Create a define-package that can make it upgrade itself.

following discussion with Nikodemus on asdf-devel.
Also, improve the way we test for upgrade.
Disable upgrade test on cmucl from asdf 2.00*.
Restore -i.bak flag in bump-version: it's actually needed.

yet avoids problems with packages and functions being destroyed by compile-file,
not yet restored by load, and yet needed by the continuation of compile-file,
by forcing a load-source-op of asdf.lisp before it is compiled, when it is compiled.
Thanks to Nikodemus for making me look deeper in fmakunbound vs unintern issues.

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