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.

Bare bones GNUmakefile and a new `bin` directory with a few
handy (?) scripts.
