Connor Clark e4a28e9e4b High-level unregistered concurrent interface (#41)
* remove parent ptr from unregistered calls -- unneeded

* begin unregistered high level server loop

* undo changes to highlevel server, add mkConfig for unregistered server

* move call CQ create/destroy into call create/destroy

* async normal call function

* preliminary unregistered server loop for non-streaming methods

* working unregistered highlevel example

* loop counters for benchmarking

* changes for benchmarking, add ruby example server for benchmarking

* async version of withCall, refactor unregistered server loop to handle all method types

* unregistered client streaming

* add remaining streaming modes

* unregistered server streaming test

* unregistered streaming tests

* add error logging

* fix bug in add example

* remove old TODOs

* fix bug: don't assume slices are null-terminated

* add TODO re: unregistered client streaming functions
