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.

Enforce exactly one trailing \n, and fix all of the existing cases.

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.

Also implement these functions for all of the bdev drivers in
the tree.

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.

Bdev modules need a separate interface than public
consumers of the blockdevs.
