* swank-asdf.lisp: Better support for different versions of ASDF.
* swank.lisp (find-definitions-find-symbol-or-package): Rename
from `find-definitions-find-symbol'. Packages are not named by
symbols and an uninterned string can refer to a package. In case
it finds a package, return a new uninterned symbol.
* contrib/slime-cl-indent.el (define-common-lisp-style "basic"): Don't set
`comment-column' to NIL, it only can accept integers.
* slime-fancy-inspector.el (slime-edit-inspector-part): New
function, tries to find a definition of the part at point. Hooks
into `slime-edit-definition-hooks'.
* swank-loader.lisp (init): Add a :quiet argument.
* swank-ccl.lisp (frame-package): Implemented.
Remove stray code.
* swank-ecl.lisp (describe-symbol-for-emacs): Include bound
symbols even those without documentation.

* slime.el (slime-print-apropos): Do some input validation to
detect bugs on the Lisp side.

* swank-backend.lisp (describe-symbol-for-emacs): Allow NIL where
:NOT-DOCUMENTED was needed.
