Allow local symbols to be referenced

Browse Source 
Local symbols can now be referenced outside the scope of their parent, by using the syntax “Parent.Chlid”.

- Local symbol names are now stored internally as “Parent.Child”.
- The symbol’s scope field no longer forms a linked list of the prior local symbols; it will now always contain the parent.
- Add the ability use EXPORT and GLOBAL with local symbols.
- Reduce duplication between findsymbol() and findpsymbol(), as well as between sym_AddLocalReloc() and sym_AddReloc().
