perl5db: use a lexical copy of $DB::sub inside DB::sub
When perl calls DB::sub in the debugger, it sets $DB::sub to the sub
being called. If we trigger any other subs to get called somewhere
inside DB::sub, this could cause DB::sub to be called again, overwriting
the global. Perl won't call DB::sub for any sub calls within the DB
namespace, but we could inadvertently trigger this via a sub override or
magic, like overloads.
Create a copy of the global value in a lexical to use inside the sub, to
avoid it ever getting overwritten.

perl5db: only check sub names for non-references
DB::sub can be called by perl giving it either a name (if it can be
determined) or a code ref. There is special handling for AUTOLOAD subs
and threads::new. This could only be happen when given the name of the
sub, so there is no need to do these checks if given a reference.
Additionally, a reference could be an object, which could have
overloads. Those overloads could fail or otherwise complicate the normal
operation of DB::sub.
Add a ref check to the sub given to DB::sub to avoid these issues.
