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.

unicode: implement higher level API for string handling2019-04-25T17:51:22ZGabriel Krisman Bertazikrisman@collabora.co.uk2019-04-25T17:51:22Zurn:sha1:9d53690f0d4e5686e80f034ea584b7a822b356d3
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.
