b5f13b368b bdev/aio: cleanup bdev_aio.h
* Remove unneeded include files.  Some of them belong in the .c file instead.
* Use create/delete_aio_bdev naming, removing aio_disk names
* Make some similar changes in the bdev_aio.c file for the associated ctx.

d3bfd244f0 bdev/aio: unregister io_device correctly
The io_device associated with the aio bdev was only
getting unregistered when the aio bdev was explicitly
deleted - not in the implicit deletion path at shutdown.

Move the io_device_unregister into the destruct_cb -
this makes sure the io_device is always unregistered, whether
the bdev is getting unregistered via an explicit RPC or
implicitly in the shutdown path.

Fixes #618.

bcff4c89b8 bdev: Rename spdk_internal/bdev.h to spdk/bdev_module.h
This will become the public interface for implementing
bdev modules. Right now the file exposes too much of
the guts of the bdev layer to modules, so it needs
to be stripped down.

dd06e98d4a bdev: rename blockdev instances to bdev
This includes file names, functions, #defines, etc.
There are still a few uses of "blockdev" outside of
include/ and lib/ - these can be handled later.

This preps for a future patch to consolidate vbdev
modules and bdev modules into just bdev modules.
