7571c2bb0c nbd: move poller out of lib into app
This allows the library user the flexibility to use a different
threading model.

It also provides a way to indicate when the connection is closed so the
app can cleanly shut down.

be9a3b9f69 bdev: pass descriptors for I/O operations
This enables checking permissions - for example,
spdk_bdev_write will fail if the descriptor was not
created with write permissions.

57d174ff67 bdev: add spdk_bdev_open/close
Retire the old claim/unclaim semantics in favor of
open/close.  Clients must now open a bdev to get
an spdk_bdev_desc, then pass this desc to get an
I/O channel.

This allows multiple clients to open a bdev,
although only one may open a bdev with write
access.

dbbde9991d test/bdev/nbd: allow building with old kernels
Older kernels do not support flush or trim operations; add #ifdefs to
allow the NBD test code to work on those kernels.

Fixes build on older distributions (e.g. CentOS 6).

f316c38783 test/bdev: add nbd test app
This utility enables accessing an SPDK block device
through the kernel using NBD (Network Block Device).

This can be helpful for running utilities like
parted on an SPDK block device for testing upcoming
GPT support.
