eCryptfs: added support for the encrypted key type

Hi there,

Either this is completely braindead, or I'm missing something very obvious. Why mess up encrypted keys with various "format" fixes.
I hope this doesn't start a trend.

The right (and disturbingly simpler) approach to fixing the auth_token vs. raw key material issue would be to put the fix in eCryptfs.

In fact, all the relevant bits for filling the token from the key_desc/sig should be moved from security/keys/encrypted/ecryptfs_format.c to fs/ecryptfs/ecryptfs_kernel.h, and all the format cruft in encrypted-keys reverted.
Then pretty much any "default" encrypted key could be used for ecryptfs…

What am I missing?
