src: code cleanup

* removed unused code: ParseFunction, ParseVariable and ParseTypeUsage. All this is handled using NameHierarchies now.
* Moved the getErrorCount method from ParserClient to the StorageAccess
* MessageFinishedParsing doesn't know the error count anymore.
* StatusBarController now has a StorageAccess to fetch the error count when needed.
