59955a12d2 event: allow unregistering a poller within its poller fn
Modify the spdk_poller_unregister() function so that it works correctly
when unregistering a poller from its own callback function.

a17ad921e2 Replace RTE_VERIFY with assert
We already require the assert header from the C standard library,
so use that instead of RTE_VERIFY to further isolate DPDK
dependencies.

Change the return type from void to int so that the result of
spdk_subsystem_fini() can be reported.

086346a4fc event: Allow idle reactors to sleep
The user can now specify a maximum delay, in microseconds, that
defines the maximum amount of time a reactor will sleep for
between polling for new events. By default, the time is 0
which means the reactor will never sleep.

5d8c94536a event: hide struct spdk_poller internals
This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).

It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.

c41ab41c17 event: add timer-based pollers
Allow pollers to be scheduled to be run periodically every N
microseconds instead of every iteration of the reactor loop.

921bf34289 event: replace poller rte_ring with TAILQ
The rte_ring used for pollers is already single-producer and
single-consumer, so it is not providing any thread safety guarantees.
ALl modifications to the active_pollers ring are done from the core that
is running the reactor (via events).  This means the rte_ring can be
replaced with a simpler intrusive linked list.

This simplifies the removal of pollers in the middle of the list and
avoids extra allocations for the ring.

c943e9ff4f trace: hard-code lcore history array size
Make sure the trace history that is exported via shared memory is always
the same size, regardless of DPDK configuration.

Also removes the necessity of including DPDK headers from spdk/trace.h
(so we have to fix up other files to include what they use).
