Add gss_userok and gss_pname_to_uid

Resurrect gss_userok and gss_pname_to_uid in the mechglue.  Add krb5
mech implementations using krb5_kuserok and krb5_aname_to_localname,
as well as mechanism-independent implementations based on name
attributes.

From r24710, r24715, r24717, r24731, r24732, r24733, r24734, r24735,
r24747, r24816, and r24819 in users/lhoward/moonshot-mechglue-fixes,
with minor edits.
