-r can now be used from the command line to specify

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

still.
Remove the Rpc sections from all configuration files

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

Some future patches will require specifying an lvol_store
name when calling spdk_lvs_init(). This means that passing
NULL for spdk_lvs_opts will no longer be an option. So
add an spdk_lvs_opts_init() (similar to spdk_bs_opts_init)
which will initialize a default value for the cluster size.
While here, prepend an underscore to spdk_setup_lvs_opts, since
this function is not part of the public SPDK API.

Always start bdev pollers on the calling core.
This removes the lcore concept from the bdev poller abstraction and
simplifies the job of spdk_bdev_initialize() callers providing their own
poller and event implementations.
All callers except the NVMe bdev hotplug poller already used the current
core as the parameter. The NVMe HotplugPollCore option was undocumented
and unused in any of the tests or example configuration files, so it
should be safe to remove.

Previously, spdk_trace_dump() took a const uint8_t * as the buffer, but
it is more flexible to allow any type to be passed (we are just going to
interpret it as an array of bytes anyway).
