[Gcl-devel] Symbols tests added

[Paul F. Dietz]

I've fixed a problem with the cl-symbols.lsp file, and augmented the tests
so that in addition to checking that the required external symbols are
in the COMMON-LISP package, they also check if the symbols have any
prohibited indicators on their property lists.  See section 11.1.2.1.1
of the spec:

   A conforming implementation must not place any property on an
   external symbol of the COMMON-LISP package using a property indicator
   that is either an external symbol of any standardized package or
   a symbol that is otherwise accessible in the COMMON-LISP-USER package.

Some symbols fail this requirement, due to the presence of DOCUMENTATION
properties (for example).

There are some miscellaneous failures: error handling in SYMBOL-NAME,
and the altered semantics of GENSYM in ANSI CL vs. CLTL1.

126 out of 1037 of the new tests fail.
