a44cd7a054 ext4 crypto: add padding to filenames before encrypting 
This obscures the length of the filenames, to decrease the amount of
information leakage.  By default, we pad the filenames to the next 4
byte boundaries.  This costs nothing, since the directory entries are
aligned to 4 byte boundaries anyway.  Filenames can also be padded to
8, 16, or 32 bytes, which will consume more directory space.

Also add the test dummy encryption mode flag so we can more easily
test the encryption patches using xfstests.
