9408745254 Streaming interface tweaks (i.e., StreamSend/Recv ops in IO) (#58)
* Add clientRW', StreamRecv', StreamSend' placeholders for IO-based stream ops (instead of Streaming); concurrent hellos Haskell client; hellos client cleanup

* Fix typo

* Rename clientRW' => clientRW; fix unreg bidi testcase

* Replace serverRW operation with one that uses the IO-based stream ops instead of the Pipes.Proxy.Client ops; modify examples accordingly

* Misc formatting, minor restructuring wibbles

* Replace remaining stream send/recv operations with IO-based ops instead of
Pipes.Proxy.Client; DCR; minor style consistency tweaks.

72160cea89 Fixes a concurrency bug wherein a thread (running beyond the maximum number of
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.
