a2dc13669a Error grants (#1025)
* CacheCork: an error Grant still says 'toT' even though it is transient

Grants with errors must be handled by a client as though no actual
permissions were obtained, so that two clients do not both end up believing
that they own a block which is only temporarily offline. However, the
Grant MESSAGE should still match the request; ie. if you did Acquire.NtoT,
the response must be Grant.toT, even though the 'error' bit signals that
the Grant actually grants no permissions.

This keeps the implementation of request-response tracking in interstitial
adapters and FSMs simple, consistent with the way multibeat errors must
include all their beats.

* Error: handle permissions properly

If two (or more) 'auto_' things have the same name, append _0 and _1 to them.

  b => b_1
  c => c
  a => a_1
