Add a new inflow type for tracking inbound flow control.
An inflow tracks both the window sent to the peer, and the
window we are willing to send. Updates are accumulated and
sent in a batch when the unsent window update is large
enough.
This change makes both the client and server use the same
algorithm to decide when to send window updates. This should
slightly reduce the rate of updates sent by the client, and
significantly reduce the rate sent by the server.
Fix a client flow control tracking bug: When processing data
for a canceled stream, the record of flow control consumed
by the peer was not updated to account for the discard
stream.
