Fast Reload Option (#1042) 
* - fast-reload, add unbound-control fast_reload

* - fast-reload, make a thread to service the unbound-control command.

* - fast-reload, communication sockets for information transfer.

* - fast-reload, fix compile for unbound-dnstap-socket.

* - fast-reload, set nonblocking communication to keep the server thread
  responding to DNS requests.

* - fast-reload, poll routine to test for readiness, timeout fails connection.

* - fast-reload, detect loop in sock_poll_timeout routine.

* - fast-reload, send done and exited notification.

* - fast-reload, defines for constants in ipc.

* - fast-reload, ipc socket recv and send resists partial reads and writes and
  can continue byte by byte. Also it can continue after an interrupt.

* - fast-reload, send exit command to thread when done.

* - fast-reload, output strings for client on string list.

* - fast-reload, add newline to terminal output.

* - fast-reload, send client string to remote client.

* - fast-reload, keep list of pending print queue items in daemon struct.

* - fast-reload, comment explains in_list for printq to print remainder.

  thread output.

* - fast-reload, fix test link for fast_reload_printq_list_delete function.

* - fast-reload, reread config file from disk.

* - fast-reload, unshare forwards, making the structure locked, with an rwlock.

* - fast-reload, for nonthreaded, the unbound-control commands forward,
  forward_add and forward_delete should be distributed to other processes,
  but when threaded, they should not be distributed to other threads because
  the structure is not thread specific any more.

* - fast-reload, unshared stub hints, making the structure locked, with an rwlock.

* - fast-reload, helpful comments for hints lookup function return value.

* - fast-reload, fix bug in fast reload printout, the strlist appendlist routine,
  and printout time statistics after the reload is done.

* - fast-reload, keep track of reloadtime and deletestime and print them.

* - fast-reload, keep track of constructtime and print it.

* - fast-reload, construct new items.

* - fast-reload, better comment.

* - fast-reload, reload the config and swap trees for forwards and stub hints.

* - fast-reload, in forwards_swap_tree set protection of trees with locks.

* - fast-reload, in hints_swap_tree also swap the node count of the trees.

* - fast-reload, reload ipc to stop and start threads.

* - fast-reload, unused forward declarations removed.

* - fast-reload, unit test that fast reload works with forwards and stubs.

* - fast-reload, fix clang analyzer warnings.

* - fast-reload, small documentation entry in unbound-control -h output.

* - fast-reload, printout memory use by fast reload, in bytes.

* - fast-reload, compile without threads.

* - fast-reload, document fast_reload in man page.

* - fast-reload, print ok when done successfully.

* - fast-reload, option for fast-reload commandline, +v verbosity option,
  with timing and memory use output.

* - fast-reload, option for fast-reload commandline, +p does not pause threads.

* - fast-reload, option for fast-reload commandline, +d drops mesh queries.

* - fast-reload, fix to poll every thread with nopause to make certain that
  resources are not held by the threads and can be deleted.

* - fast-reload, fix to use atomic store for config variables with nopause.

* - fast-reload, reload views.

* - fast-reload, when tag defines are different, it drops the queries.

* - fast-reload, fix tag define check.

* - fast-reload, document that tag change causes drop of queries.

* - fast-reload, fix space in documentation man page.

* - fast-reload, copy respip client information to query state, put views tree
  in module env for lookup.

* - fast-reload, nicer respip view comparison.

* - fast-reload, respip global set is in module env.

* - fast-reload, document that respip_client_info acl info is copied.

* - fast-reload, reload the respip_set.

* - fast-reload, document no pause and pick up of use_response_ip boolean.

* - fast-reload, fix test compile.

* - fast-reload, reload local zones.

* Update locking management for iter_fwd and iter_hints methods. (#1054)

fast reload, move most of the locking management to iter_fwd and
iter_hints methods. The caller still has the ability to handle its
own locking, if desired, for atomic operations on sets of different
structs.
