...because fewer special cases are better. This also resolves everything but the documentation for capnproto#423. One of the tests had to be reworked a bit because the exact sequence of messages was a bit different, but still correct.
Per Louis's questions.
This will simplify transitioning to using the rc package for refcounting. Right now there is a bug where one of the tests is failing with an error about multiple shutdowns -- I think this is likely equivalent to capnproto#348 (the done channel is gone), but it seems to be deterministic now.
This Shutdown() is redundant with the one in clientPromise.shutdown(). When capnproto#348 was filed, this was a close() on the done channel instead of a call to ClientHook.Shutdown, but became the latter after merging calls and refs -- done was for the former, Shutdown() for the latter. I'm still not 100% sure why this used to be non-deterministic.

This patch:
callsandrefsfields inclientHook, removing thedonechannel.It includes #502, so we should merge that first -- though I haven't yet pinned down the test failures. The last two commits are the parts relevant to this change.
