Revert making identifier types generic over the underlying string type
At the same time, this commit makes `ServerName` a newtype around str so
other identifier types can borrow out their server name part as a
`&ServerName`. This technique works for `ServerName` because it keeps no
additional metadata. For the other identifier types to support being
created in borrowed form from a string slice, custom DSTs first have to
be added to Rust.
