d4e565b41b blobcli: fix bugs where freed memory is not NULL
There are a few places where we check for a NULL * to make
decisions and in both shell and script modes, any command
sequence loads and unloads the bs (self contained) so when
multiple actions are taken and some value that was freed
isn't NULL we can end up with segfaults.

866f15b3ac blobcli: refactoring and cleanup
Some refactoring around functions that need to load the
blobstore as a first step was done as general cleanup. Function names
were also updated for consistency, some comments cleaned up
and #defines added for clarity.

c5e63c71ff blobcli: add interactive shell mode
All of the same commands and options are available but by
starting with the -S option the user enters an interactive
shell mode to interact with blobstore significantly
improving response time by only having to init DPDK and NVMe
subsystems one time.

e9cf3ecf14 blobcli: add hot remove callbacks
Commit 99ba2b25e6 ("lvol: hotremove support") added new parameters to
spdk_bdev_create_bs_dev(), but it was merged after the blob cli, which
didn't get updated to add the new parameters.

Just pass NULL as the hot remove callback for now (no hotplug support in
blobcli).

8fbbfccdd5 app: blob cli
The CLI is intended to serve as both example code and a tool for
developers learning/kicking the tires of blobstore. Initial
functionality includes:

- initialize a blobstore
- list available bdevs or blobs
- create a new blob of a specific size
- set the superblob ID
- show detailed info for a blob
- show detailed info for the blobstore
- set/delete an xattr pair for a blob
- fill a blob with a value
- import a local file to a blob
- dump a blob to a local file

The CLI requires an NVMe backend and uses both the SPDK app
framework and the bdev layer.
