use shared_ptr to manage symbol_scope objects * symscope.h, symscope.cc (symbol_scope_rep): New class, renamed and adapted from symbol_scope. (symbol_scope): New class to manage symbol_scope_rep with shared_ptr. Change all uses of pointers ot symbol_scope objects to be symbol_scope objects or, in a few cases, pointers to symbol_scope_rep objects instead.
