Simon Rozman 11f5780250 wintun: Revise interface creation wait 
DIF_INSTALLDEVICE returns almost immediately, while the device
installation continues in the background. It might take a while, before
all registry keys and values are populated.

Previously, wireguard-go waited for HKLM\SYSTEM\CurrentControlSet\
Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\<id> registry key
only.

Followed by a SetInterfaceName() method of Wintun struct which tried to
access HKLM\SYSTEM\CurrentControlSet\Control\Network\
{4D36E972-E325-11CE-BFC1-08002BE10318}\<id>\Connection registry key
might not be available yet.

This commit loops until both registry keys are available before
returning from CreateInterface() function.

Simon Rozman b7025b5627 wintun: Add TUN device locking 
In case reading from TUN device detected TUN device was closed, it
closed the file handle and set tunFile to nil. The tunFile is
automatically reopened on retry, but... If another packet comes in the
WireGuard calls Write() method. With tunFile set to nil, this will
cause access violation.

Therefore, locking was introduced.

Simon Rozman 6581cfb885 wintun: Move exchange buffer in separate struct on heap 
This allows buffer alignment and keeps it together with its meta-data.

Furthermore, the write buffer has been reduced - as long as we flush
after _every_ write, we don't need a 1MiB write buffer.

Simon Rozman c15cbefc12 Reorder data-types and functions to match SetupAPI.h 
Adding functions with non-consistent order made setupapi package a mess.
While we could reorder data-types and functions by alphabet - it would
make searching easier - it would put ...Get... and ...Set... functions
quite apart.

Therefore, the SetupAPI.h order was adopted.

is harmless. It just returns ERROR_INVALID_HANDLE - we have a unit test
for this in TestSetupDiDestroyDeviceInfoList().
