Now spdk_bdev_create_bs_dev() opens the underlaying spdk_bdev.
Due to that spdk_bdev should be closed when bs_dev is destroyed.

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.

It is not actually useful to be immediately returned
a handle to the bdev_io. There isn't anything valid
that the user can do with it at that point. Instead,
return an integer error code.

Instead, coalesce unmaps for contiguous clusters to reduce

The user should not see the bdev_io status directly; the NVMe and SCSI
error code wrappers provide the ability to translate to the desired
format regardless of what kind of error is stored inside the bdev_io.
Replace the spdk_bdev_io_completion_cb status parameter with a bool
simply indiciating whether the I/O completed successfully.

This is the initial commit for "blobfs", a lightweight
filesystem built on top of the SPDK blobstore.
Also included in this patch:
1) a shim for using SPDK bdevs as the backing store for
SPDK blobstore/blobfs
2) documentation for using blobfs as the storage engine
with RocksDB
3) scripts for running a set of workloads and collecting
profiling data with RocksDB and blobfs
See doc/blobfs/getting_started.md included in this commit
for more details on blobfs, including some of the current
limitations.
