lastidnotfound step 2:
* move "record stage", aka poh_service into banking stage
* remove Entry.has_more, is incompatible with leader rotation
* rewrite entry_next_hash in terms of Poh
* simplify and unify transaction hashing (no embedded nulls)
* register_last_entry from banking stage, fixes#1171 (w00t!)
* new PoH doesn't generate empty ledger entries, so some fixes necessary in
multinode tests that rely on that (e.g. giving validators airdrops)
* make window repair less patient, if we've been waiting for an answer,
don't be shy about most recent blobs
* delete recorder and record stage
* make more verbost thin_client error reporting
* more tracing in window (sigh)
* Move recycler instances to the point of allocation
* sinks no longer need to call `recycle`
* Remove the recycler arguments from all the apis that no longer need them
* Use multiple sockets for receiving blobs on validators
- The blobs that are broadcasted by leader or retransmitted by peer
validators are received on replicate_port
- Using reuse_addr/reuse_port, multiple sockets can be opened for
the same port
- This allows the kernel to queue data to user space app on multiple
socket queues, preventing over-running one queue
- This helps with reducing packets dropped due to queue over-runs
Fixes#1224
* Fixed failing tests
