ed159eae1b bdev: Eliminate spdk_bdev_io::ctx
The user can get there via the bdev, so this didn't
have a purpose.

c97ea5ad8d bdev: Modules no longer register bdevs as io_devices
Instead, they register some internal structure of
their choosing.

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.

b58a5d73ef util: add SPDK_COUNTOF() array size macro
SPDK_COUNTOF works like sizeof, except it returns the number of elements
in an array instead of the number of bytes.

2931a3efef event: remove 'complete' parameter from poller_register
The spdk_poller_register() function provides a way to pass an event to
call once the poller is registered, but it is always NULL in the current
code base.

d27b24c94b log: split internal TRACELOG macro into new header
The SPDK_TRACELOG macro depends on a CONFIG setting (DEBUG), so it
should not be part of the public API.

Create a new include/spdk_internal directory for headers that should
only be used within SPDK, not exported for public use.

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.

22b12b319e rbd: fix the pool_name and rbd_name wild pointer issue
Previously, we directly assigned the pointer of pool_name
and rbd_name, and this is not safe. After the rpc test,
we found the string value is not correct, so use strdup.
