r11270: Move the core CrackNames code from rpc_server/drsuapi to dsdb/samdb.

I'm sure this will not be the final resting place, but it will do for
now.

Use the cracknames code in auth/ for creating a server_info given a
principal name only (should avoid assumtions about spliting a
user@realm principal).
