6a72c19ee2 blob/bdev: Add an API spdk_bdev_create_bs_dev_ext()
spdk_bdev_open_ext() requires the caller to use bdev_event_cb_t
and bdev_event_cb_t is more extensible than bdev_remove_cb_t.
Hence use bdev_event_t as an argument.

spdk_bdev_open_ext() calls spdk_bdev_get_by_name() inside and
spdk_bdev_create_bs_dev_ext() calls spdk_bdev_open_ext() inside.
The caller needs to know if the spdk_bdev_get_by_name() succeeded.
Hence spdk_bdev_create_bs_dev_ext() returns return code by return
value and returns the created bs_dev by double pointer.

3cba062b86 blob_bdev: add spdk_bdev_create_bs_dev_from_desc
New interface for create spdk_bs_dev from bdev desc.
This change, together with spdk_bdev_open_ext, can
remove the race condition where user gets the bdev
structure, but bdev is removed after getting that
structure and before spdk_bdev_create_bs_dev function
is called.

19100ed580 bdev: rename spdk_bdev_module_if -> spdk_bdev_module
This better matches the style in the rest of SPDK.

No functional change - this is a pure find/replace of
spdk_bdev_module_if to spdk_bdev_module.  Instances of this struct will
be renamed in another patch.

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.
