9c35e39c54 event: Move spdk_poller_register to io_channel
Make this generic and not directly dependent on
the event framework. That way our libraries can
register pollers without adding a dependency.

4bcfef0021 rpc: remove rpc subsystem
RPC is core functionality for SPDK applications and should always
be initialized last (after all subsystems have been initialized).
So make RPC a first class citizen and integrate it with the
app framework directly instead of making it an "optional" subsystem.
Then we initializing it after all subsystems have completed
initialization, and tear it down before tearing down subsystems.

We can also do some other cleanup while here - for example, reactors
are already started when spdk_rpc_initialize() is called, so remove
the extra event that was added during initialization since this is no
longer needed.

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.

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.
