Konrad Sztyber 91b30e7aec test/external_code: initial definitions for basic NVMe driver
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`.

This directory is meant to demonstrate how to link an external application and bdev module to the SPDK libraries. The makefiles contain six examples of linking against spdk libraries. They cover linking an application both with and without a custom bdev. For each of these categories, they also demonstrate linking against the spdk combined shared library, individual shared libraries, and static libraries.

This directory also contains a convenient test script, test_make.sh, which automates making SPDK and testing all six of these linker options. It takes a single argument, the path to an SPDK repository and should be run as follows:

sudo ./test_make.sh /path/to/spdk

The application hello_bdev is a symlink and bdev module passthru_external have been copied from their namesakes in the top level SPDK github repository and don't have any special functionality.
