Vhost needs to register memory given by guest in VFIO container to be
able to do any DMA using this memory.
Currently DPDK doesn't provide any interface to handle guest memory, so
for now lets find container fd in /proc/self/fd/ directory and provide
some VFIO internal API that finally should extend DPDK API.

The new format is: domain.bus.device.function
For this format, since we use '.' as separator,
to avoid misusing, we only support the following:
1 domain.bus.device.function ( 4 values provided)
2 bus.device.function (3 values provoided with domain = 0)
3 bus.device (2 values provided with domain = 0, function = 0)

According to the scsi standard, all ASCII data fields "may be
terminated with one or more ASCII null (00h) characters"
[7.6.10, 4.4.1]. Windows SCSI Compliance tests expect a null terminator
there, so let's include it.

A 100us is so small that applying the quirk to the specific
SSDs that require the delay is more trouble than it is worth.
So remove the quirk and always wait 100us before re-enabling
the NVMe SSD during initialization.

Also avoid an spdk_get_ticks() call in the default
case where a timeout_cb_fn is not defined.
On my Intel(R) Xeon(R) E5-2699 v3 system with an
Intel(R) P3700 SSD, these modifications reduce software
overhead per I/O by 3-5% (as measured by the SPDK
overhead tool).

The bdevperf reset test only executes in the nightly test run, so this
problem wasn't caught during review.
It gets stuck in an infinite loop and produces lots of log output; turn
it off to avoid filling up the disk with logs until we determine what
broke it.

Several examples have a function to associate workers
with threads. Simplify that algorithm.
This seems to just shift some of the complexity
from register_workers down to main, but in the long
run the DPDK threading will get abstracted into
env as well and greatly simplify that part.
