a4747c6048 env: Make the environment library configurable.
This allows users to swap out SPDK's third party
libraries for an implementation based on their own
framework.

a30b5532cb memory: Rename to env
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.

6b1e4e732d Drop libpciaccess and switch to DPDK PCI
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.

a17ad921e2 Replace RTE_VERIFY with assert
We already require the assert header from the C standard library,
so use that instead of RTE_VERIFY to further isolate DPDK
dependencies.

0babf8ce81 bdev, copy: move all I/O paths to use I/O channels
bdev and copy modules no longer have check_io functions
now - all polling is done via pollers registered when
I/O channels are created.

Other default resources are also removed - for example,
a qpair is no longer allocated and assigned per bdev
exposed by the nvme driver - the qpairs are only allocated
via I/O channels.  Similar principle also applies to the
aio driver.

ioat channels are no longer allocated and assigned to
lcores - they are dynamically allocated and assigned
to I/O channels when needed.  If no ioat channel is
available for an I/O channel, the copy engine framework
will revert to using memcpy/memset instead.

f93bb8a32d Switch spdk_bdev_read/write arg order for length and offset.
This matches the general order (LBA start then LBA count) for
the NVMe API.

While here, fix a copy/paste error in a debug message (write
instead of writev).

d2ea70cafd iscsi: use spdk/endian.h functions
Switch from the non-portable <sys/endian.h> functions (htobeXX/beXXtoh)
