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.

Simplify the build rules so that common libraries are always linked.
Also fix up a couple of -lpciaccess instances that should have been
changed to $(PCIACCESS_LIB).

Previously, there was no way to determine what namespace ID was assigned
when a namespace was created via the NVMe library interface.
Also drop the incorrect comment about calling
spdk_nvme_ctrlr_process_admin_completions(), since
spdk_nvme_ctrlr_create_ns() checks the admin queue internally.

Add a helper function, get_lba_format(), to print available LBA formats,
and use it in Create Namespace as well as Format NVM.

Resolve relative paths before using them to clean up command lines.
This should also help shorten the overall command line length that gets
embedded in the binary and used when locating the executable from a
coredump.

Fit all of the info about a controller onto a single line. This is more
readable with larger numbers of controllers.

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.

The previous method for registering I/O queues did not allow the user
to specify queue priority for weighted round robin arbitration, and it
limited the application to one queue per controller per thread.
Change the API to require explicit allocation of each queue for each
controller using the new function spdk_nvme_ctrlr_alloc_io_qpair().
Each function that submits a command on an I/O queue now takes an
explicit qpair parameter rather than implicitly using the thread-local
queue.
This also allows the application to allocate different numbers of
threads per controller; previously, the number of queues was capped at
the smallest value supported by any attached controller.
Weighted round robin arbitration is not supported yet; additional
changes to the controller startup process are required to enable
alternate arbitration methods.
