This adds a case insensitive hash function to allow taking the hash
without needing to allocate a casefolded copy of the string.
The existing d_hash implementations for casefolding allocate memory
within rcu-walk, by avoiding it we can be more efficient and avoid
worrying about a failed allocation.

Temporarily cache a casefolded version of the file name under lookup in
ext4_filename, to avoid repeatedly casefolding it. I got up to 30%
speedup on lookups of large directories (>100k entries), depending on
the length of the string under lookup.

This patch integrates the utf8n patches with some higher level API to
perform UTF-8 string comparison, normalization and casefolding
operations. Implemented is a variation of NFD, and casefold is
performed by doing full casefold on top of NFD. These algorithms are
based on the core implemented by Olaf Weber from SGI.
