First this change moves spdk_subsystem_fini() to trigger on
spdk_app_stop(). This ensures that spdk_subsystem_fini() is called
before reactors are stopped in spdk_reactors_stop().
Finish paths for subsystems, bdevs and copy engine is now
asynchronous.
Each of those three mentioned have to make sure they are
asynchronous as well.
Only bdev that currently has requirement for asynchronous finish
are logical volume.
Thus the change in vbdev_lvol.c making it move to next bdev module
only after all lvol stores were unloaded.
Fio_plugin finish of bdev and copy_engine was removed for now.
Next patch in series adds it back with async support.

Always start bdev pollers on the calling core.
This removes the lcore concept from the bdev poller abstraction and
simplifies the job of spdk_bdev_initialize() callers providing their own
poller and event implementations.
All callers except the NVMe bdev hotplug poller already used the current
core as the parameter. The NVMe HotplugPollCore option was undocumented
and unused in any of the tests or example configuration files, so it
should be safe to remove.

Closing the framework has to go through all subsystems
without failure, so return codes are unnecessary.

Much like bdev modules inside the bdev directory,
add a subsystems directory inside of event. The subsystem
specific code for the bdev library is placed in to
a separate library in that directory, breaking the
strict dependency of the bdev library on the event subsystem
code.
