70c3e1f2eb reactor: add context_switch_monitor RPC
This allows the user to enable/disable getrusage() monitoring at
runtime.

Also change the log level to INFO and enable the monitoring in all
builds, not just #ifdef DEBUG.

c588baab29 reactor: add pid to names for rings and mempools
This is required for using the event framework
in multi-process mode since they must be unique
across the group of processes..

Currently the stub app calls into the env layer
directly, bypassing the event framework, so this
issue would only be seen with multiple secondary
processes using the app framework.  Some future
changes will change the stub app to use the event
framework which necessitates this change immediately.

52bbb267d8 event: process events in batches
Since we are usually going to be removing multiple events from the queue
at once, use the DPDK burst dequeue interface to improve efficiency.

Also rework the event queue runner to always process a fixed maximum
number of events per timeslice for simplicity.  This removes the
rte_ring_count() call from the hot path and improves fairness between
events and pollers.

Now that events are dequeued in bulk, we can also put the event objects
back into the mempool in bulk.  Add an env wrapper around
rte_mempool_put_bulk() and use it to free all of the events at once.

Basic performance benchmark using test/lib/event/event/event -t 10
is improved: previously ~40 million events per second, now ~46 million
events per second.

d4d82fc3ab event: directly add poller when adding to current core
This is required since pollers are now directly removed
(rather than scheduling an event) when the unregister call
is made on the poller's lcore.

Without this change, if a poller is registered then
immediately unregistered, the unregistration will seg
fault since the event adding the poller has not executed
yet.

Also add a test case that exhibits the sequence of events
described in this commit message.
