Pass the entire myuser_t* to svslogin_sts()

Some protocol modules, like nefarious, want to access other fields than
just `->name`; this avoids having to call myuser_find() just to find the
same myuser that's already known. (Ref: #248)

It does, however, change the protocol module API.

nickserv/{info,status}: show entity ID in 'ACC' and 'INFO'

As in issue #253, it would be useful to uniquely identify users across
account renames and such. Privacy issues (/ns info ?<eid>) should not be
a problem, since there already are other ways to chase account renames.
