Add unicode_strtitle() for Unicode Default Case Conversion.
This brings the titlecasing implementation for the builtin provider
out of formatting.c and into unicode_case.c, along with
unicode_strlower() and unicode_strupper(). Accepts an arbitrary word
boundary callback.
Simple for now, but can be extended to support the Unicode Default
Case Conversion algorithm with full case mapping.
