tilelink: split Acquire into Acquire{Block,Perm} ( #1030 )
...
We had planned for a while to add an 'Overwrite' message which obtains
permissions without requiring retrieval of data. This is useful whenever
a master knows it will completely replace the contents of a cache block.
Instead of calling it Overwrite, we decided to split the Acquire type.
If you AcquirePerm, you MUST Release and ProbeAck with Data.

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

diplomacy: place Monitors inside LazyModules sinks
...
We used to place Monitors at the point of the ':='.
This was problematic because the clock domain might be wrong.
Thus, we needed to shove Monitors a lot.
Furthermore, now that we have cross-module ':=', you might not even
have access to the wires at the point where ':=' is invoked.
