Changes since the last version of the patches
* Filename encryption now uses ciphertext stealing mode, which is more
space efficient
* Fixed a bug when deleting encrypted htree directories w/o the key available
* Cleaned up comments, copyrights, and whitespace
* The encryption feature is not advertised via /sys/fs/ext4/features
* Remove unneeded Kconfig dependencies (CTR, SHA1, SHA512, and HMAC)
* Cleaned up and refactored the file name and data path crypto code
* Support encrypted fast symlinks
* Lots of other cleanups suggested by reviewers (thanks, all!)
Note: this version of the patches requires e2fsprogs commit
v1.42.12-522-ga672190 or newer.
