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.

Use the len field from the generic spdk_bdev_io instead of duplicating
it in blockdev_rbd_io.

It was written but never read (and the I/O channel is already stored in
the generic spdk_bdev_io).

No need to duplicate the bdev-defined I/O type.

The status field in blockdev_rbd_io was only used within
blockdev_rbd_io_poll(), so replace it with a local variable.

Remove the complex list management for pool_name and just strdup() it
directly. It is not worth the trouble to save a few bytes.

Make a wrapper that spdk can call a function without thread affinity, and
call this wrapper to open rbd image.

Rename the construct_rbd_bdev "size" parameter to block_size so that it
is consistent with other bdev construct RPCs.

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.

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.

This patch enables vector operation for bdev drivers aio, malloc and
nvme.
The rbd driver still handle only one vector.

This patch removes the lock in RBD module. And it requires
the librbd library supports rbd_poll_io_events function.

This patch will add a new bdev module, rbd.
It can make ceph rbd as the backend of iSCSI
target.
