Joel Stanley 96d12c1e6c Preliminary streaming mode support (client streaming, server streaming, bidirectional) (#37)
* Tweak runOps param order, inline common op sequences, clean up serverHandleNormalCall

* More ops sequence inlining for clarity, experimenting with Managed

* Checkpoint: preliminary support for all streaming modes; much cleanup/refactoring and api design still needed

* Use mempty for default StatusDetails; tweak bad status matching mechanism

* Preliminary user-facing, server-streaming, low-level api and test

* renaming wibbles

* Preliminary user-facing, client-streaming, low-level api and test

* Move sendMsgs comb to Network.GRPC.LowLevel.Op; misc cleanup/DCR

* Modify bidi streaming to omit request payload

* Add transformers dep

* Preliminary user-facing low-level bidirectional streaming api and test

* Fix missing peek import

* Remove TimeoutSeconds params on streaming mode functions

* Fix serverHandleNormalCall rebase wart

* Fix rebase warts; minor hlint fixes and wibbles

* Post-rebase tweaks to optional payload use in serverRequestCall (i.e., now respects payloadHandling again)

* Cleanup/refactor serverRequestCall

* Fix comment

* Change ServerRWHandler type so that handler does not have to invoke a finalizer

* Change ServerReaderHandler type so that handler does not have to invoke a finalizer

* Simplify serverWriter interface and ServerWriterHandler structure

* Simplify serverRW (get rid of exec param), improve bidi streaming tests

* Use ExceptT in serverRW impl

* Change ServerRWHandler type to pass recv/send operations.

* Renaming

* Define ClientRWHandler, pass recv/send ops

* wibbles

* Use ExceptT in clientRW impl

* Add DataKinded phantom typing to RegisteredMethod; misc cleanup

* Simplify sendMsgs interface; add SingleSend type and related helpers

* Rename SingleSend to SendSingle, use ExceptT to clean up {client,server}Writer and sendMsgs

* More ExceptT cleanup in clientWriter

* Factor out reusable bits of clientWriter

* Shrink ServerReaderHandler

* Delete stale comments

* Use common machinery for all streaming modes; make handler types more consistent

* wibbles
