Instead of requiring each bdev module to track its own bdevs and clean
them up during its fini callback, we can walk the list of registered bdevs
during spdk_bdev_finish() and call spdk_bdev_unregister() on each one of
them before cleaning up the bdev modules.

Disambiguate the log components from the trace functionality
(include/spdk/trace.h).
The internal spdk_trace_flag structure and related functions will be
renamed in a later commit - this is just a find and replace on
SPDK_TRACE_* and SPDK_LOG_REGISTER_TRACE_FLAG().

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.
