39cc59635a build: include -lrt and -lpthread in LDFLAGS
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).

cd48a01fcb build: wrap $(CURDIR) relative paths in $(abspath)
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.

4ad99808f2 nvme: allow user to override controller defaults
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.

5ee7a5df37 nvme: add spdk_nvme_ns_is_active() function
This function returns true if the namespace is active or false if it is
inactive (e.g. no namespace has been attached to the specified namespace
ID yet).

Also use the new function to add checks in the examples and tests where
applicable.

8374a727a9 nvme: refactor nvme_attach() into nvme_probe()
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.

c02b179490 Remove year from copyright headers.
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./'
