This patch introduces initial definitions for a stripped down version of
an out-of-tree NVMe driver. It's purpose is to showcase SPDK's
interfaces for writing user-space drivers for various types of devices.
The choice of NVMe as the example is based on the fact that it can be
emulated by QEMU and the code can be borrowed from SPDK's regular NVMe
driver.
This driver will only provide the most basic functionalities (e.g.
device probing, controller initialization, only admin queue support,
etc.) and won't have support for any device quirks. Therefore, it's
only intented to be used with emulated devices.
In addition, an application utilizing the driver to list all available
NVMe controllers and print their identify data will be added. It'll
be a very basic, stripped down version of `examples/nvme/identify`.
