This will allow removal notifications to be propagated to the library
user (e.g. for hotplug).
The callback is currently unused, but this at least prepares the API for
the future hotplug support.

Provide a new structure, spdk_nvme_ctrlr_opts, to let the user modify
the default controller initialization options during probe/attach.
Currently, only the number of queue pairs can be modified in this way;
other options will be added later.

Rename all functions with a spdk_ prefix, and provide enough of an API
to avoid apps needing to #include <pciaccess.h>.
The opaque type used in the public API for a PCI device is now
struct spdk_pci_device *.

The new probing API will find all NVMe devices on the system and ask the
caller whether to attach to each one. The caller will then receive a
callback once each controller has finished initializing and has been
attached to the driver.
This will enable cleanup of the PCI abstraction layer (enabling us to
use DPDK PCI functionality) as well as allowing future work on parallel
NVMe controller startup and PCIe hotplug support.

Also add a space between Copyright and (c).
The copyright year can be determined using git metadata.
Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.
Performed using this command:
git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'

This more accurately represents what function it performs.
Also remove pci_device_has_uio_driver() from the public API. Callers
should use pci_device_has_non_uio_driver() instead.

If any command fails during the asynchronous event request test, exit
the test with an error rather than waiting for an event that won't
arrive.

Replace {0} initializers with {}, since it is equivalent and simpler
(and avoids the warning).

This helps enable FreeBSD, where pciaccess pci_device_has_kernel_driver()
is not functional. The function will return 0 if there is no driver
attached, or the Linux uio or FreeBSD nic_uio driver is attached. It will
return 1 otherwise.
