We will be needing an infrequent chore to check which nodes are in the
reverify queue and synchronize that set with the 'contained' field in
the nodes db, since it is easily possible for them to get out of sync.
(We can't require that the reverification queue table be in the same
database as the nodes table, so maintaining consistency with SQL
transactions is out. Plus, even if they were in the same database, using
such SQL transactions to maintain consistency would be slow and
unwieldy.)
This commit adds a method to the class representing the reverify queue
in the database, allowing us to get the list of every node that has at
least one record in the reverification queue.

Adding a new worker comparable to Verifier, called Reverifier; as the
name suggests, it will be used for reverifications, whereas Verifier
will be used for verifications.
This allows distinct logging from the two classes, plus we can add some
configuration that is specific to the Reverifier.
There is a slight modification to GetNextJob that goes along with this.
This should have no impact on operational concerns.

audit.Queues was the previous method of passing stacks of segments for
audit to the verifier. As of commit 68f9ce4a, this is now happening
by way of the auditor queue (database-backed, so that communication can
happen between multiple peers). audit.Queues is no longer needed.

GetByNodeID will allow querying the reverification queue to see if there
are any pending jobs for a given node ID. And thus, to see if that node
ID should be contained or not.
Some parameters on the other methods of the ReverifyQueue interface have
been changed to accept pointers; this was done ahead of the rest of the
changes for the reverification queue to better match the signatures of
the methods that these will replace once ReverifyQueue is actually being
used (meaning fewer changes to tests).

The audit chore will be pushing a large number of segments to be
audited, and the db might choke on that large insert when under load.
This change divides the insert up into batches, which can be sized
however is optimal for the backing database. It also arranges for
segments to be inserted in the order of the primary key, which helps
performance on some systems.

Since the auditor will be moving to a different process from the
metainfo loop, we need a way of communicating which segments have
been chosen for audit. This queue will be that communication, for now.
Contrast this with the queue for _re_verifications in commit 9c67f62f.

This table will be used as a queue for pieces that need to be reverified
(a regular audit timed out on the owning node, so now that node is
contained and we need to validate the piece before un-containing it).

* The audit worker wants to get items from the queue and process them.
* The audit chore wants to create new queues and swap them in when the
old queue has been processed.
This change adds a "Queues" struct which handles the concurrency
issues around the worker fetching a queue and the chore swapping a new
queue in. It simplifies the logic of the "Queue" struct to its bare
bones, so that it behaves like a normal queue with no need to understand
the details of swapping and worker/chore interactions.

* Do not swap the active audit queue with the pending audit queue until
the active audit queue is empty.
* Do not begin creating a new pending audit queue until the existing
pending audit queue has been swapped to the active queue.
