First pass at replacing PDDictionary with a proper hash map.
Temporarily disabling hash maps.
Work on multibyte character support, not finished.
Double-strdup fix.
Replaced PDDictionary with hash map implementation. Performance is slightly bad for sparse dictionaries (0.018 s slower per 1 million ops) but exponentially better as size grows.
Moved profiling flag to pd_internal and added maxCount when enabled to dictionary struct.
Removed hash map files.
