Improved error reporting, particularly for macro expansion.

* eval.c (last_form_expanded): New variable.
(do_expand): New static function; contains previous expand
function.
(expand): Becomes a wrapper for do_expand, with re-entry
counting.
(eval_init): GC-protect last_form_expanded.

* eval.h (last_form_expanded): Declared.

* parser.l (regex_parse, lisp_parse): Just use a simple word for
the name of the regex or string parse location, not the entire
expression itself.

* unwind.c (uw_throw): Check whether expansion was going on
when the unhandled exception was thrown and print additional
information.
