* fixes #1663 Request/Reply Protocol Throughput and ScalabilityGarrett D'Amore2023-12-16
| | | | | | | | | | | | | | | This eliminates the req protocols use of nni_timer (and setting a single timer node per request. This was problematic because it devolves into O(n^2) as we wind up inserting timer nodes and having to scan the list for the timer node. The solution is to use a single scan - stop worrying about insertion, but instead use a coarse granularity timer (defaults to 1 second) for retries. Then do the O(n) scan just once per interval. A new option, NNG_OPT_REQ_RESENDTICK, can be used to change the tick interval for cases (like unit tests) where more fine grained timing is required.

This is not quite complete, but it sets the stage for other protocols (such as zmq or mqtt) to be added to the project.
