Joel/highlevelv2 (#40)
* 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 * begin high-level server interface * update to datakind representation * clean up * move method type info to type level, parametrize ServerCall by payload * convert for writer handler * start switching over to Message-based handlers * begin work on highlevel example * comment out old code * parametrize StreamSend * parametrize StreamRecv * conversion for ServerReaderHandler * finish handler conversions * Add high level version and payload checking to echo-client * Decouple server CQs from call-bound CQs (registered methods); use more consistent naming conventions * Decouple server/call-bound CQs for unregistered methods; refactor U.serverRequestCall; misc cleanup * Make convertRecv total; formatting wibbles
