5aae23aa08 test/bdev: handle the error case the IO channel is not setup
This issue may be hit under some large IO and large queue
depth cases where much memory will be consumed and the channel
may be failed to create due to insufficient memory.

The general fix here is that we need to properly handle
the error case that the channel is not created due to this
or that reason.

a0da65f49d bdevperf: adjust the bdevperf task number.
According to my analysis, the exact number is not
related with core number, which should be calucated
as g_target_count * g_queue_depth. Since each
target will be run I/O by differnet cores.

And it would solve the task number not enough issue.

6bef902ca5 rpc: add default UNIX domain socket listen address
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.

15c96c6601 bdevperf: Fix the display name issue.
This patch does the following work:

1 Fix the performance display name issue. When doing
the io statistics, we call spdk_bdev_get_name, however
this time, we are already calling spdk_app_stop, so
we lost the name info. Currently code, we will not
see the correct name. And this patch will help to fix
this issue, by storing the name at the begining.

2 Fix memory leak issue. It seems that we do not free the target
space.

Retire the old claim/unclaim semantics in favor of

This allows multiple clients to open a bdev,
although only one may open a bdev with write

a871d5e5d7 test/bdevperf: validate inputs are positive integers
Negative queue depths, I/O sizes or time durations do
not make sense, so exit() if user input contains any of
those cases.

133c4a70c1 bdevperf: save offset and unmap desc in bdevperf_task
This is preferable to rooting around the bdev_io structure
directly - which will no longer work if we want to support
modifying bdev_io structures in place for simple
bdev transformations like partitions.

249a68e92b bdev: add API to claim block devices
Claim the block devices used by iSCSI LUNs and NVMe-oF subsystems so
they can't accidentally be reused.

This will also be used by virtual block devices to allow layering of
bdevs.

a96dc2592e bdev: remove event dependency from I/O callback
Use a plain function pointer + callback context for the bdev I/O
completion callback.  This is possible now because each I/O channel will
be polled on the core that submitted the I/O.

d2ae4f0723 test/bdev: do not free io channels in completion callback context
A future patch will call the bdev callback routine directly, rather
than deferring the callback routine to an event.  So for these
tests we will no longer be able to free io channels in the context
of the callback routine - otherwise it will result in freeing
an NVMe I/O queue pair in the callback routine and then return
to the NVMe driver which will try to reference the now deleted
qpair.

44ef085bed event: pass arg1 and arg2 directly to event fn
This allows the elimination of the spdk_event_get_arg1() and
spdk_event_get_arg2() macros, which accessed the event structure
directly; this was preventing the event structure definition from being
moved out of the public API header.
