for each installed cl-* port.
Previously, some fasl files were either rebuilt when running as
root, or failed to load due to permission errors for normal users.
sometimes the build would fail because of "missing" packages that
weren't actually missing (this only happened in ports that aren't
committed yet).
Rewrite the FASL placement code using the asdf-binary-locations
extension, which is already included in the cl-asdf port but needs
to be installed from ports when building for SBCL (which has its
own ASDF code). The binary-locations code generates paths unsuitable
for PLISTs, therefore it has been overridden with
lisp-specific-fasl-subdir.
Because of the new code, PLIST generation for cl-*-sbcl and cl-*-clisp
ports is now entirely automated.
All dependent cl-* ports are upgraded (obsolete code removed,
PORTREVISION bumped).
The asdf-init.lisp script was changed to support the bundled ASDF
libraries in lang/ccl and lang/sbcl. Therefore, it can be safely
loaded by both (also by lang/clisp) to enable the ASDF framework.
