Yeah, I thought about doing that myself, to eliminate some unnecessary
key duplication in the GSSAPI code, but eventually settled on the side
of laziness.

Since we already have krb5_key reference counting, the hardest part is
choosing names, since we can't rename the old functions to say
"keyblock" instead of "key".  Perhaps appending _k to the original
functions would be sufficiently evocative:

  krb5_auth_con_getkey_k
  krb5_auth_con_getsendsubkey_k
  krb5_auth_con_getrecvsubkey_k
