Marking this as ready for review

Benchmarking not showing a significant difference (only comparing unary requests obviously). There is one extra allocation in the new code, likely related to the new stream structure.

You don't have to have the plugins = here.

Implementation of the 1.2 protocol with support for streaming. Provides
the client and server interfaces for implementing services with
streaming.

Unary behavior is mostly unchanged and avoids extra stream tracking just
for unary calls. Streaming calls are tracked to route data to the
appropriate stream as it is received.

Stricter stream ID handling, disallowing unexpected re-use of stream
IDs.

Add flag to indicate that a data message used with a close flag
is not sending any data. This clears up any ambiguity over whether the
final data message is transmitting a zero length data message or no
data at all.
