Since bs_dev cannot be created on device twice,

It prevented blobcli from displaying information
for blobstore underlying lvol store.
This patch remove vbdev_lvol from list of bdev modules

Will follow this up with a doc change but want to make sure we're
all good with it first. This is meant to not only beef up
blobstore testing but provide the 'match' utilitiy for all test
cases where we are currently calling an executable and either
counting only on a return code to determine success or failure
or worse yet we're just running it and if it doesn't explode we
assume its a pass.
The 'match' util was borrowed from the PMDK folks after first
adding the "ignore" feature upstream to make it easier to use
in SPDK. It works like this:
When the developer checks in a test they create and check in
the output of the test with two different file extensions:
.ignore: should include a string per line for output lines
that we want to totally ignore typically because they're
platform specific so the output could be different from
machine to machine. In this case I'm ignoring all output
lines with 'DPDK' or 'EAL' or '...' in them. The first
few are obvious, the last is because the test tool will
print a varrying number of these as progress indicators.
.match: this is a copy of the output that the developer
'fixes' up by replacing platform specific output strings
with replacable tokens as described in the 'match' help.
This is where you'd want to match an entire line minus
something like a CPU count or free block count or
something. The 'ignore' feature was added simply so we
wouldn't have to edit every single line of an output
file that had DPDK or EAL in it.
Then you modify the test script to save the output and
smply run the match util providing the name of the
match file and if it fails to match the actual output
with the saved output that's been token'ized the script
will error.
The obvious advantage here is that now we can confirm all
of the output from a test executable is as we expect.

Currently, each histogram range is hardcoded to
128 buckets (1ULL << 7), resulting in 58 ranges
(64 - 7 + 1) and a total size of 58 * 128 *
sizeof(uint64_t) = 59392 bytes.
To allow for more usage models in cases where this
size is prohibitive, enable the following changes:
1) specify number of buckets per range (in number of bits)
2) specify max datapoint value (in number of bits)
The latter can be useful for cases where datapoints
are never close to requiring all 64 bits - and allows
reducing the number of ranges. Any data points that
exceed the max will be tallied in the last bucket
in the last range.
Testing shows no performance disadvantage using the
dynamic approach.

spdk_blob_data will continue to contain global state for
the blob. In the future spdk_blob will point to an
I/O channel for the blob - for now it effectively still
points to the spdk_blob_data, but by changing the
structure names here it will reduce the code churn in

Finish paths for subsystems, bdevs and copy engine is now

Each of those three mentioned have to make sure they are

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

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.

Patch 2b37c71 [1] introduced the
spdk_bdev_finish() call on the
fio_plugin shutdown. That happens
after all the fio threads have
stopped. Patch 19ddb10 [2] introduces
an extra poller that has to be
stopped during spdk_bdev_finish().
Prior to this patch fio_plugin
pollers couldn't be stopped if their
corresponding threads have been
already stopped - but that's a
behavior we want.
