 subject: Send explicit salt for SALTTYPE_NORMAL keys
 target_version: 1.7
 tags: pullup

 Change the signature of _make_etype_info_entry to take the canonical
 client principal instead of the request structure.  Also fixes the salt
 we compute for SALTTYPE_NOREALM keys.

 Sending an explicit salt for SALTTYPE_NORMAL keys is believed to be
 necessary for some preauth scenarios involving aliases.
