Also force close handles when deleting the adapter, in case the function
is called from another process, for example an uninstaller.

When Windows 7-8.1 support is sunset, there will be no more EV driver
deployment at all.

When we install the Wintun driver to the store, we get exact oem<nn>.inf
filename of the driver in the store we just installed. Since the
installation should be only temporarily, we should uninstall only the
driver we installed.
This also eliminates the need for iterating driver store speeding up
things.
The code we removed was inherited from the installer.dll, where it made
perfect sense to remove all installed Wintun drivers in the update
process.

With all the platforms (including ARM) having at least one driver now,
the dead-code removal #ifdef-s are no longer required.

This adds the ARM driver to the list of Wintun drivers we compile for
future deployment. Since we're not in position to test it in the real
world, any feedback is greatly appreciated.

...and change to inheritable only the ones really needed, eliminating a
window where we'd have inheritable handles that are not supposed to be
inheritable.

Silently ignoring truncation of the strings(like adapter and pool names,
registry paths etc.) leads to strange failures later down the road (like
registry key not found) masking the true reason of the failure. This
makes troubleshooting difficult.

The .sys file of the driver does not need to be digitally signed. It is
the .cat file that Windows is checking for complete driver .inf+.sys+
.cat bundle.

We must not use the process heap, as it is changeable. Client may change
it causing our HeapFree() to use wrong heap.

Rather than every client reinvent the art of using the Wintun and its
ring buffers, we offer helper structs and functions to unify and
simplify Wintun usage.

RegistryQueryString() may produce one or more "File not found" errors
when called from RegistryQueryStringWait() - which is expected while
waiting. Those errors were annoying and awkward to read in the log.
Furthermore, should RegistryQueryString() fail, it already displays
detailed Windows error message and the parent's logging was simplified
to prevent repetitions in the log.
