Some platforms require that a specific file extension is used for
executables. Append $(EXEEXT) to $(APP) definitions to accommodate
this. The name EXEEXT has been chosen for consistency with automake
which uses the same variable for the same purpose.
Add extensions for generated files used by Windows to the 'clean' target
(.obj, .lib, .pdb) and add output files to .gitignore.
Tested using a cross compiler that forces a .exe suffix and verifying
that all LINK messages include the correct suffix and that a second
call to make does nothing (showing that the targets match the
generated executables).

MinGW builds require a thin layer above the standard libraries to
provide POSIX functionality that is missing on Windows. Add support
for building this.
MinGW cross builds are experimental and work is ongoing to integrate
them into the CI and test environment. Including the changes at this
stage is being done to facilitate that process.
The layer has been arranged in the same way as DPDK and is
accessed as an external build using ./configure --with-wpdk=<dir>.
Support has also been added for using a default ./wpdk in
preparation for reaching the required level of stability.
The help text for ./configure indicates that support for --with-wpdk
is experimental.
Further details and instructions can be found at https://wpdk.github.io.

The shadow registers need to be zero when the qpair is

is used for the first time, since the page is allocated

the qpair again with the same qid.
So clear the registers in nvme_pcie_ctrlr_delete_io_qpair,
just after the cq is deleted.

Added getters/setters providing access to several of the NVMe
controller's registers. Only the registers that are needed for the
initialization are implemented.
For now all of them are unused, so they're marked as external to avoid
the -Wunused-function warnings. The subsequent patches will make use of
them and mark as static appropriately.

The controller's memory register space (located in the first BAR) is now
mapped. The functions for accessing individual registers from this area
will be added in the following patch.

The identify app can now be used in two modes:
- without any parameters it'll attach to all available NVMe controllers
and print each one out,
- with a single parameter specifying the BDF address of the controller
it'll only attach and print out information about that controller.

Added interface, nvme_connect(), for connecting an NVMe device specified
by a BDF address. Similarly to spdk_nvme_connect(), it returns a
pointer to an NVMe controller representing requested device.
Under the hood, it uses spdk_nvme_pci_device_attach() to attach the
PCI device.

The NVMe devices can now be enumerated, attached, and detached. To
simplify the driver, the probing step has been omitted - all available
controllers are attached and need to be detached later.
The driver registers itself as a PCI driver via a call to
SPDK_PCI_DRIVER_REGISTER() and then uses spdk_pci_enumerate() to
enumerate available NVMe devices and attach them.

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`.
