unicode: reduce the size of utf8data[]
Remove the Hangul decompositions from the utf8data trie, and do algorithmic decomposition to calculate them on the fly. To store the decomposition the caller of utf8lookup()/utf8nlookup() must provide a 12-byte buffer, which is used to synthesize a leaf with the decomposition. This significantly reduces the size of the utf8data[] array.
