The NVMf target is being refactored to split the RDMA transport-specific
code into its own file. Once this is complete, we should be able to
plug in other transports and build the NVMf target without any RDMA
dependency if desired.
To enable this, change the CONFIG option to RDMA; it still controls
whether the whole NVMf target is built for now, but once the RDMA
dependency is actually made optional, we will be able to build the
generic NVMf target code without libibverbs installed.

Instead of always defining config values, only #define options that are
enabled, so that #ifdef/#ifndef can be used. Generate #undef lines for
the disabled variables so the names are still visible in config.h.

All source files will now depend on config.h, which is generated based
on the defaults in CONFIG and the command line arguments passed to make.
This ensures that any configuration changes, including on the command
line, cause a full rebuild.

Use 'git grep -I' to determine the list of files that git considers to be
text (rather than hardcoding a list of known text file extensions) and
check all of them for newline at end of file.

cleanup.sh and unbind.sh have been combined into a single
setup.sh that takes one optional parameter (reset). If no
parameter is given, the script will automatically bind
all NVMe and IOAT devices to either uio_pci_generic
or vfio-pci, as appropriate based on IOMMU settings. If
the reset parameter is given, the devices will be bound back
to the appropriate kernel drivers.

Since the grep would fail for most devices and the result wasn't
checked, the script would exit on the first device ID that didn't match.
Also initialize $rootdir so ioat_pci.h can be located.

This patch is used to detect the nvme and ioat devices
in the tested platform and bind it to uio_pci_generic
driver. Thus, when we can smoothly use pci device functions
provided by DPDK instead of using libpciaccess.

This will rmmod nvme on Linux, and use the DPDK nic_uio driver
to unbind nvme devices from the nvme driver on FreeBSD.
"nic_uio" is actually a misnomer - it is not NIC driver specific,
and can safely be used to bind NVMe devices to an effectively
null driver.
