2491021f64 nvmf: convert nvmf_tgt into an event subsystem
This is required as part of our effort to build a single target app that
can run e.g. NVMe-oF and iSCSI targets in the same process.

3fb4bc717b vhost: move app fini to the vhost subsystem
We already have a vhost subsystem and have to do

Technically, any SPDK app can use vhost library
and create vhost devices, so we need to delete them
on shutdown in all cases - in module fini.

601bcbcf66 util: extend cpumask to hold more than 64 cpus
Fixes github issue #218.

This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.

spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.

This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.

d34d32f684 event: Replace the constant SPDK_MAX_REACTORS to spdk_env_get_last_core()
SPDK reactor is one per cpu and SPDK_MAX_REACTORS is used as the
maximum number of cpus locally in the file.

When the maximum number of cpus is changed, SPDK_MAX_REACTORS is likely
to fail to be changed.

Adopting two improvements for iSCSI by Ziye to the reactor will be safer
than now for the reactor.
- iscsi/conn: remove rte_config.h header
- env: export spdk_env_get_last_core function

-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.

fbb9430ec4 app: add spdk_app_parse_args()
This is a helper function that eliminates a lot of
duplicated code in our target applications, specifically
around common command line argument parsing and usage
messages.  This patch only moves the iscsi, nvmf and
vhost targets to use this function, but there are other
test/example applications that could also take advantage
of it to reduce duplicated code and improve consistency.

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.

40dd3c29a4 event: create the ring on other available sockets
There may have the situation that associated socket does
not have enough memory for the event pool and the related
ring buffer. As the event pool will be created at any
available socket, this will be same for the ring.

The basic idea is to first allocate the memory for the
core associated socket and then try other available sockects
before terminating.

6c54c13cd4 event/subsystem/bdev: asynchronous SPDK finish
First this change moves spdk_subsystem_fini() to trigger on
spdk_app_stop(). This ensures that spdk_subsystem_fini() is called
before reactors are stopped in spdk_reactors_stop().

Finish paths for subsystems, bdevs and copy engine is now
asynchronous.
Each of those three mentioned have to make sure they are
asynchronous as well.

Only bdev that currently has requirement for asynchronous finish
are logical volume.
Thus the change in vbdev_lvol.c making it move to next bdev module
only after all lvol stores were unloaded.

Fio_plugin finish of bdev and copy_engine was removed for now.
Next patch in series adds it back with async support.

8eef5183d3 bdev: remove spdk_bdev_poller_start() lcore option
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.
