Summary: ASDF should use define-condition :report

Initial Comment:
Hi,

I wondered why ASDF-1.86.1 badly reports errors in 
CLISP:

"(asdf:oos "asdf:load-op "clsql-odbc")
; loading system definition from 
S:\Code\Lisp\clsql-3.0.3\clsql-odbc.asd into #<PACKAGE 
ASDF14729>
;; Loading file S:\Code\Lisp\clsql-3.0.3\clsql-odbc.asd 
...
;; Loaded file S:\Code\Lisp\clsql-3.0.3\clsql-odbc.asd
*** - Condition of type ASDF:MISSING-COMPONENT.
The following restarts are available: [...]"

The specific error message "missing component foo" does 
not appear in the debugger.

Bruno Haible has now been convinced that ANSI CL contains 
sufficient wording to mandate that printing of condition objects 
must go through PRINT-OBJECT. As a consequence, GNU 
CLISP has been changed to take PRINT-OBJECT methods on 
condition classes into accound. I no longer claim that it's a bug 
in ASDF.
