* BUG: The 256 values of an input byte were mapped to just 128 bits of the
trie children mask, so corruption could have happened with non-ASCII keys.
* BUG: Add a special case when using GB.AddString() on an empty key
* BUG: Fix a memory error from Trie.Complete()'s return value
* OPT: Use the Gambas API in trie.c to manage memory and thus remove error
recovery since the interpreter will crash anyway
* OPT: Remove checks for "unsupported" characters as all 256 values of a
byte are supported in this version of the code
