The new env library will wrap all third-party library
calls and be easily swappable with alternate implementations
at build time. For now, it's just the memory library
renamed.

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.

Provide a convenience wrapper for general purpose dataset
management commands. The previous wrapper for deallocate
was difficult to use correctly and only for deallocate.
Note that the name is "dataset_management" as opposed to
"data_set_management" to match the NVMe specification.
It's questionable whether "dataset" is valid English, but
it is best to match the specification.

Rather than requiring changes to a static list of header files, use the
GNU Make wildcard function to generate a .cpp file per header.
This also tests whether each header includes all of the system headers
for the types it uses.

This code calculates the difference between two pointers and then stores
it in an off_t, which is intended for file offsets.
In this particular case, the offset will never be large enough to
overflow off_t, but use the correct ptrdiff_t type anyway.

off_t is problematic for use as a file/block offset: it is signed, and
on 32-bit platforms, it can be 32 bits (depending on the settings of
_FILE_OFFSET_BITS and _LARGEFILE_SOURCE).
The blockdev layer already uses uint64_t to represent offsets; replace
the blockdev module uses of off_t in internal functions with uint64_t
to match.
