This patch adds support for spdk_bdev_readv in scsi layer.
It also fixes write so that it uses multiple iov's instead of one.
Currently we should use only task->iov (for single vector operation)
or task->iovs (for multiple vector operations).

- I/O queue IDs are now allocated by using a bit array of free queue IDs

the queue pair at startup, and one to reinitialize an existing qpair

For large writes that require multiple SCSI tasks (one for immediate
data, then one or more for R2T-solicited data), we bump the refcount
for the task associated with the initial immediate data PDU, to
ensure it does not get freed until all of the child tasks are
completed. But in some cases this initial immediate data PDU could
complete after all of the R2T-soliciated data PDUs. The
completion code was not handling this case correctly which would
result in the iSCSI connection thinking it still had outstanding
SCSI tasks when the connection closed.

This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.
Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.
