The vbdev_* functions that were declared in lvol.h are all internal to
the lvol vbdev implementation; they don't need to be in the public
header.
vbdev_get_lvs_bdev_by_lvs() is moved to the top of the file so it
doesn't need a forward declaration (no code change).

Modify the vbdev_get_lvol_store_by_uuid() API function to take the UUID
as a string instead of a uuid_t, since this simplifies the calling code.
This also allows us to remove #include <uuid/uuid.h> from the public
API, giving us the freedom to change the underlying UUID implementation
later if necessary without breaking API.

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.

at that point it is known that it can be used. Meanwhile removing
was done at start of _vbdev_lvs_remove, to prevent possibility to
access it when waiting for destruct callback to complete.
This made checking if the g_spdk_lvol_pairs list is empty unreliable
to detect if all lvs were destroyed - they could still be being
processed and callback not yet called.
This patch removes lvs from global list only after the callback of
_vbdev_lvs_remove is called.
It will be used in future patch during asynchronous
