Connection profiles shown on the login screen using PLAP
requires automatic service that starts openvpn.exe
processes for these profiles.
This commit adds an attempt to start the service from
PLAP dll. The service is started only if any PLAP enabled
profiles are found.
As starting the service can spawn up OpenVPN.exe processes and
the GUI may attach to them, auto-connect in the GUI is
suspended during session lock to leave the connections free to
be controlled from PLAP screen.

- instantiate OpenVPN PLAP provider which will enumerate configs
in config-auto directory.
- Attempt to connect each config found one after the other
The test program is deliberately written in C++ as that's how most
Windows programs (and likely, LogonUI.exe) may use the COM object.
Note that duplicate configs are ignored, so ensure that config
files in config-auto are not "shadowed" by identical named one's
in user's profile or in global config folder.
Additional notes:
The test program is not linked to the plap dll.
Instead it finds the module using CoGetClassObject,
so the plap dll must be registered in the system.
It also tests dynamically loading the dll from
C:\Program Files\OpenVPN\bin\libopenvpn_plap.dll
which should succeed even if the registration is not
proper.

This header has been recently added to mingw-w64 on our
request. Until its available in released versions,
wget it from mingw-w64's github repo.
Only affects autotools-based builds -- MSVC builds will pick the
native header.

- Dialog windows of connections can popup at any time due to
restarts not in user's control. Avoid this by marking current
current profile being connected, and intercepting dialogs for
other profiles.
This is implemented by hooking into management callbacks such as
OnPassword, OnNeedOk etc.

- COM interfaces for ICredentialProvider and
IConnectableCredentialProviderCredential combined
with a trimmed down user-interface implemented as
libopenvpn_plap.dll
- Connections autostarted by OpenVPNService are enumerated
as possible PLAP connections. The user is expected to leave
these in management hold so that "connect" will popup any
required user dialogs.
To use:
- Register the dll as a PLAP provider (see included .reg files)
- The enumerated connections will show up as tiles in the PLAP
screen of the login desktop (secure desktop).
