At startup, use reference count to detect completion and
move to the next step. By returning completion message to the init
thread, we can avoid using any atomic operation.
At shutdown, we can use spdk_for_each_channel() conveniently. Put

spdk_put_io_channel().
Moving login acceptor to a dedicated thread is another task.
To maintain the original behavior, number of threads created is

This is a preparation to support voluntary thread termination by
calling spdk_thread_exit().
Previously, the exiting thread had discarded all pending mesasges.
We change this to stop accepting any new message in spdk_thread_send_msg()
and reap pending messages in _spdk_msg_queue_run_batch().
Add unit test case for the new behavior. Adding g_ prefix to global
variables for clarification is done together.

Add spdk_thread_is_exited() to check if the thread is marked as
exited. This API will be used by reactor to destroy the thread
which exited voluntarily.

Rename all variables and comments related with timed poller from
timer_poller to timed_poller.
This patch was originally to count poller and add the current
value to thread_get_stats RPC. This will be realized to add
thread_get_pollers RPC instead but renaming will be valuable itself.
So keep only renaming in this patch.

All of the code now goes through the transport plugin system,
so this isn't necessary.
While doing this, caught a bug that the get_registers function
wasn't being set for the PCIe transport.
