Support for encrypted lofi devices

With the integration of the code developed for PSARC 2007/001 Opensolaris supports encrypted lofi devices:

The lofi(7D) driver will gain the ability to encrypt/decrypt the raw blocks. This provides parity with Linux and MacOS X which both have encryption support in their equivalent to the lofi(7D) driver.
