  eCryptfs: check for eCryptfs cipher support at mount (2012-07-13 17:20:34 -0700)

----------------------------------------------------------------
- Fixes a bug when the lower filesystem mount options include 'acl', but the
  eCryptfs mount options do not
- Cleanups in the messaging code
- Better handling of empty files in the lower filesystem to improve usability.
  Failed file creations are now cleaned up and empty lower files are converted
  into eCryptfs during open().
- The write-through cache changes are being reverted due to bugs that are not
  easy to fix. Stability outweighs the performance enhancements here.
- Improvement to the mount code to catch unsupported ciphers specified in the
  mount options
