NDIS >=6.30 allows bringing adapter to low-power state without pausing
it. As Wintun's pause cancels all pending IRP and we want to keep
disturbing client to a minimum, OID_PNP_SET_POWER cancels pending NBLs
and wait for active NBLs to finish only.

All parameters to TunOidSet/TunOidQuery() are contained inside a
NDIS_OID_REQUEST struct. But, the main rationale behind this commit is
that OID_PNP_SET_POWER set request will require pointer to original
NDIS_OID_REQUEST struct for NdisMOidRequestComplete() call, should we
want to implement pending PnP power-down.

This time we don't impose 8-space tabulators, but merely suggest text
editors to use tabulator indenting. Otherwise, Visual Studio IDE
configured to use spaces instead of tabulators keeps corrupting
indentation.

Screen is a valuable real-estate on small displays or when working in
less than maximized or full-screen Visual Studio IDE.
This commit replaces tabulators used for horizontal alignment with
spaces, and stops imposing 8-space tabulators on everyone.

Device name actually uses LUID index only. Not an entire LUID. IfType
in LUID is always 53 (IF_TYPE_PROP_VIRTUAL).

This also introduces a proper queueing and refcounting system, which
should increase performance and allow for IRP cancelation.

If device connection is not terminated on NDIS pause, the driver doesn't
unload when adapter is disabled. This also prevents driver updates
without reboot.

The ActiveNBLCount must be bumped _before_ adapter state is checked.
Otherwise, there is a window of code that may allow adapter transition
from pausing to paused state, followed by a
NdisMIndicateReceiveNetBufferLists() call.
