* AbstractFrontier
remove inbound/outbound queues; simplify managerThread
perform findEligible/schedule/receive/finish immediately
* WorkQueueFrontier
eliminate holdQueues setting
synchronize sendToQueue on target queue
make findEligibleUri reentrant; rely on [Blocking|Stored]Queue thread-safety
make arriving at front of ready trigger for 'active'/budget-session
simplify inactiveQueues management
simplify waking from overflow
* WorkQueue
redefine 'active' as in-budget-session
rename 'held' as 'managed'
synchronize major methods, relying on allQueues cache that operations on same intended queue use identical instance
split over-budget test to isOverSessionBudget and isOverTotalBudget
have toString show classKey
* BdbFrontier
checkpoint fixes: remember nextOrdinal, rotate frontier-recover log, reset queues on recovery
consistencyCheck method for probing state during stress tests
* RecordingInputStream.java

force a format before publish(), to benefit above (a small hit in other cases where it's redundant)
* (many)
distinction between these two constant-collecting classes was fuzzy (to the point that they already referred to each other), and they were both in same subproject/package already as well; so, merged constants into the larger, older class
* WorkQueueFrontier
(findEligibleURI) avoid outbound.capacity-sensitive activation, which under a race created by recent changes led to infinite recursion here
* AbstractFrontier
(next) when nothing is immediately ready, try adding one-at-a-time to outbound, rather than fillOutbound()
* AbstractFrontier
(drainInbound) don't assume current thread will be able to take() full batch; poll() and exit early if other threads have drained queue first
* AbstractFrontier, WorkQueueFrontier
synchronize around all InEvent/findEligibleURI actions, so that drainInbound and fillOutbound may be called outside managerThread
whenever a ToeThread would block on enqueue() or next(), try the appropriate catch-up method before blocking
remove assertions no longer true with activity happening outside managerThread
