FS-9775: Significant work towards supporting BEP44, "get" is nearly working committing to merge routetable updates

FS-9775: Fixed autorouting, must be checked before message generation as the message may include a nodeid that is specific to the endpoint used

FS-9775: Changed local nodeid to be per endpoint, and removed ks_dht_node_t in preparation for changes based on route table discussions

FS-9775: Some refactoring for consistency, reduction of nodeid to simpler type, added preliminary type for node to track externally after discussions on route table responsibilities

FS-9775: Added preliminary support for processing find_nodes query, including calls to compact addresses and node info

FS-9775: Refactored sending of messages to utilize a more scalable and throttled queue for outgoing messages

Also added support to send error message responses and updated the test to confirm, errors still need to be updated to send an error responses

FS-9775: Fixed some bugs, unit test now successfully sends, processes, responds, and receives and validates a ping, more on this soon

The use of salloc in the main ks_dht_t for the inner nodeid suggests salloc calls
should be renamed prealloc to avoid confusion where not used on stack variables

This will be replicated to other allocations

Code compiles, but not yet functional, unit tests to come soon for current code

This reverts commit ea0f5d20.

   Pipelining of requests to improve throughput
     -- new parameter max-pipelined-requests (default 20) for maximum number of requests to batch at one time

   Deletion of counter keys when zero
     -- new parameter delete-when-zero (default false) to enable.  This will cause a redis eval to execute to decrement counters instead of DECR.

   Detection of negative limit counters
     -- Self healing of negative counters (due to key eviction, etc)
