- Split the part that gets a PCI device's address into its own function,
spdk_pci_device_get_addr(). This is useful outside of the comparison
function and is orthogonal to comparing addresses.
- Make the comparison function take two addresses instead of a device
and an address. The more general form will be useful with addresses
that are not directly associated with a device. Because of this, also
rename the function from spdk_pci_device_compare_addr() to
spdk_pci_addr_compare().
- Return a signed value similar to strcmp() so that addresses can be
ordered, not just compared for equality.

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).

Rather than embedding adminq directly in the spdk_nvme_ctrlr structure,
change it to a pointer to a spdk_nvme_qpair. This is necessary to allow
the transport to extend the qpair structure.

This requires a couple of related changes:
- I/O queue IDs are now allocated by using a bit array of free queue IDs
instead of keeping an array of pre-initialized qpair structures.
- The "create I/O qpair" function has been split into two: one to create
the queue pair at startup, and one to reinitialize an existing qpair
structure after a reset.

This is required since pollers are now directly removed
(rather than scheduling an event) when the unregister call
is made on the poller's lcore.
Without this change, if a poller is registered then
immediately unregistered, the unregistration will seg
fault since the event adding the poller has not executed
yet.
Also add a test case that exhibits the sequence of events
