It was not obvious from the type how many times the
final field of ClientReaderRequest would be invoked.
(Assuming it is invoked once per stream increment
results in a hang, which can be confusing.)
* Expose the max receive message length channel argument + unittest
* `ClientError` GADT ctor => `ClientErrorResponse`, expose `ClientError`
Prior to this commit, the name `ClientError` was both:
- The name of a data constructor name for the `ClientResult` GADT
- A name of an internal sum type for capturing different kinds of client
errors
We want to expose the latter to users of the library, and so expose the latter
and rename the former.
* Remove unused `MultiWayIf` lang ext
Instead of making a blocking foreign call without a timeout, we set a
timeout of one second. This way, the thread returns in Haskell code (and
thus is interruptible) at least every second. This is useful in order to
be able to kill `Server`s, see
https://github.com/awakesecurity/gRPC-haskell/issues/22.

pluckers) would register a CQ notification via
grpc_server_request_registered_call prior to obtaining pluck permission, block
on acquiring such permission, and thus miss notification of the server call.
The bug can could be witnessed with particular interleavings by ensuring that
GRPC_MAX_COMPLETION_QUEUE_PLUCKERS server threads are blocked on their own
server call notifications, and then using the
(GRPC_MAX_COMPLETION_QUEUE_PLUCKERS+1)th server thread to attempt to block on a
notification for an additional server call.
In order to fix this, we simply extended the pluck permission held window for
serverRequestCall, and created a variant of pluck (called pluck') which assumes
permission to pluck is already held by the calling thread.
