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.

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

ATTENTION: incompatible change to component-name-to-pathname-components
Also, have compile-file* heed a :output-file parameter.

Bump versions in code and documentation.

Add tests for configuration files.
Also export enable-asdf-binary-locations-compatibility.

Thanks to tcr for suggestions.

Simplify test scripts.

perl -pi.bak -e 's|"../asdf"|\(compile-file-pathname "../asdf"\)|;' *.script

Found that the current load recipe (load "../asdf") in the test
scripts was brittle, because the presence of asdf.fasl was obscured
if there was an "asdf/" directory in ..  Unfortunately, the result
of makeinfo --html asdf.texinfo created just such a directory!
fe[nl]ix kindly provided a pointer to compile-file-pathname that
solved the problem.
