9d73eed8a6 bdev: Consistently pass user context to fn_table calls
Some calls were passing bdev->ctxt, some calls just
bdev. In most of our implementations those are the
same pointer, but they aren't necessarily.

6d7b6e882c bdev/aio: The user now provides the names of AIO bdevs
The user now must choose the name for each AIO bdev. This
provides consistency for names across restarts.

1e85d9ef32 bdev_module.h: move to spdk_internal/bdev.h
This is consistent with the other internal-only API headers.

0404c306cb bdev: make construct RPCs return the bdev names
When creating a bdev via the RPC interface, there was no way to know
what name it was assigned (other than predicting it based on the
numbering scheme).  Change all of the relevant RPC interfaces to return
an array of bdev names so they can be used to construct LUNs/subsystems
dynamically in scripts.

0babf8ce81 bdev, copy: move all I/O paths to use I/O channels
bdev and copy modules no longer have check_io functions
now - all polling is done via pollers registered when
I/O channels are created.

Other default resources are also removed - for example,
a qpair is no longer allocated and assigned per bdev
exposed by the nvme driver - the qpairs are only allocated
via I/O channels.  Similar principle also applies to the
aio driver.

ioat channels are no longer allocated and assigned to
lcores - they are dynamically allocated and assigned
to I/O channels when needed.  If no ioat channel is
available for an I/O channel, the copy engine framework
will revert to using memcpy/memset instead.

a30b59fa33 aio: create blockdev_aio_io_channel abstraction
This breaks out the resources needed to perform
aio-based I/O into a separate data structure, as a steps
towards some future patches that will enable per-thread
resources to enable parallel I/O without synchronization.

6e09a48e42 bdev: Separate the module header from the public header
Bdev modules need a separate interface than public
consumers of the blockdevs.
