The asio upgrade of 0.1.13 brought us over the limit of 65k
entitities in a single compilation unit. /bigobj allows more
methods
The ovpn3-core.vcxproj already uses this flag
Set proxy settings in registry:
HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings
If process is running under SYSTEM account, we impersonate to
logged-in user to access HKEY_CURRENT_USER.
After modifying proxy setting we need to tell Windows to refresh those,
we do it if process is running under user account. Unfortunately WinInet API
we use is not available for services, even with impersonation, so
user application should take care of refreshing settings.

Implemented full TunClient class for Windows with TAP driver
support. For now, we use netsh (rather than TAP driver DHCP)
to set all tunnel adapter properties, as this appears to work
great on Windows 7.
IPv6 is fully supported.
Known isues:
* netsh doesn't have a command for adding DNS search domains, so
we don't support them yet.
* While we always try to remove routes and added properties from
TAP adapter instance when we close out the session, for robustness,
when we bring up TAP adapter, we should try to delete any stale
routes on interface left over from previous session.
* Right now we call netsh with system(). For security and
compatibility with Windows apps (not only console apps),
we should use CreateProcess instead.
