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.

c303ba2c16 blobstore: close bdev on destroy
Now spdk_bdev_create_bs_dev() opens the underlaying spdk_bdev.
Due to that spdk_bdev should be closed when bs_dev is destroyed.

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.

aff7e226f7 bdev: spdk_bdev_[read|write|flush|unmap|reset] now return int
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.

b9bcc3531e bdev: make enum spdk_bdev_io_status private
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.

1edd9bf3e4 blobfs: Add a lightweight filesystem built on the blobstore
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.
