RPC is a default feature required for almost all usages,
so enable RPC by default, but with a UNIX domain socket
for security reasons.
-r can now be used from the command line to specify
an alternative RPC listen address from the default
/var/tmp/spdk.sock.
Remove the Enable parameter from the Rpc config section
but still allow specifying an alternative listen address
using the Listen parameter as an alternative to the
command line option. This keeps backward compatibility
for this release for anyone using the configuration file
still.
Remove the Rpc sections from all configuration files
that were using them, except for those that specified
alternate TCP ports for multi-process test cases. We
can fix these later to use an alternate UNIX domain
socket and to use the command line instead.

So make RPC a first class citizen and integrate it with the

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

The end goal is to have the application create one poll group per core.
Then each poll group will have a single CQ per network device and an I/O
channel per back-end storage device to poll.
This is just the first step toward that, which is to wire up the
creation of the per-core poll groups in the application.
Note that the app poll groups don't do anything yet. We'll need
additional library API changes to make the library use the existing poll
groups, rather than creating a new poll group per subsystem as we do
right now.

This will be used in a future patch to ensure we do not
allow creating or loading an lvolstore with a names that
matches an already opened lvolstore.

Unmap does not guarantee that erased blocks will return all zeroes.
using write_zeroes when unmapping metadata gives the
desired behavior for a blob.
Only metadata pages will be cleared with write_zeroes in this patch;
blob data clusters will still call unmap. This behavior may be made
configurable in a later patch (to allow the user to request zeroing of
clusters rather than just unmapping).

if write_zeroes is not supported by the block device, we can get the
same behavior by simply writing a buffer full of zeroes to the blocks
we want to erase. I also incorporate splitting into the bdev layer to
accomodate large i/o.

Currently exposed API allows to load/unload and to
initialize blobstore on a device.
A spdk_bs_destroy() call is added in order to reach
functional parity with spdk_bs_init(). It was not
possible to remove blobstore from device from within
SPDK previously.
spdk_bs_destroy() takes blobstore pointer as argument
(instead of bs_dev), because blobstore has to be already
loaded to destroy it.
