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.
Changes made by Gabriel:
Rebase to mainline
Fix checkpatch errors
Extract robustness fixes and merge back to original mkutf8data.c patch
Regenerate utf8data.h
