Ingo Franzki 296eb39c60 Changes to support PHMAC with integritysetup and cryptsetup ...

Make the PHMAC integrity algorithm know to libcryptsetup.

The size of a key for PHMAC is not known, because PHMAC gets an opaque
blob as key, who's physical size has nothing to do with the cryptographic
size. Thus, let INTEGRITY_key_size() and crypt_parse_integrity_mode()
return the required_key_size as key size for PHMAC, or -EINVAL if
required_key_size is zero, to indicate that the size is unknown.
