BUILD/MAJOR:updated 51d Trie implementation to incorperate latest update to 51Degrees.c 

Trie now uses a dataset structure just like Pattern, so this has been
defined in includes/types/global.h for both Pattern and Trie where it
was just Pattern.
In src/51d.c all functions used by the Trie implementation which need a
dataset as an argument now use the global dataset. The
fiftyoneDegreesDestroy method has now been replaced with
fiftyoneDegreesDataSetFree which is common to Pattern and Trie. In
addition, two extra dataset init status' have been added to the switch
statement in init_51degrees.
