Replace usage of rte_vhost_driver_enable_features() by
setting disabled_features field dynamically.
This patch doesn't change functionality, but simplifies
initialization and removes usage of socket operation.
Call to drive_enable_features() had to be done when
features field was static, but now it is mutable so
the call became redundant.

This will enable us to make features dynamic, dependent on underlying
backend device, and to remove usage of rte_vhost functions in
vhost-blk implementation which will improve encapsulation
and enable us to write tests that use vhost-blk functions directly.
Dynamic features are used in vhost_blk, but backend structure is
assumed to be static, so we had to call
rte_vhost_driver_enable_features() after registering it with
some features initially disabled.
This patch moves feature fields to vdev structure where it
can be set dynamically.

These bdevs claim native support for zcopy operations. They should
actually support them when running on top of a bdev that claims zcopy
support.
For example, if you were to build a part or passthru bdev on top of a
malloc_bdev (which is just for testing primarily) and then try to run
bdevperf on top of that, you will currently get errors. This patch fixes
that problem.

may resubmit them to the controller. When the controller was removed
the submission path will return -ENXIO and we will free the requests directly,
so the callback will not be trigerred for these requests. Here we added a

Add an API so that the user can enable/disable the bdev IO
timeout. Also, add the bdev io timeout handling callback.
So it means to let the upper user determine how to handle
the IO timeout scenario reset the device or abort the IO.

This is a useful utility function.
The end goal of this patch series is to create a python utility that can
be called upon to dump information about DPDK allocated memory in a
human readable way.

SPDK has swithed to DPDK rte_vhost library since 19.04 release, the internal
rte_vhost library is not recommended any more, but we still would like to
use it for vhost_nvme until we can switch to the new NVMe virtualization
solution. Fix the compilation issue here, the internal SPDK rte_vhost
library can still work well with vhost blk/scsi/nvme target for now.

Some version of firmware on Intel SSDs exhibit poor performance
with an IO queue size of 256 (the SPDK default). Add a quirk to
account for this - and use the same size as the Linux driver (1024)
instead.
If the user specified a controller option to explicitly set the
io_queue_size different than the default, the quirk will not take
effect. Note that users can still override the io_queue_size when
creating the qpair - this only changes the ctrlr's default
io_queue_size.
