Remove tap-win32

Introduce tap-windows.h which is modified tap-win32/common.h.
Except of function rename, it is the same without the tap_id.
This file should be provided as part of tap-win32 MSI.
For now we hold a copy.

-; Note to Developers:
-;
-; If you are bundling the TAP-Win32 driver with your app,
-; you should try to rename it in such a way that it will
-; not collide with other instances of TAP-Win32 defined
-; by other apps.  Multiple versions of the TAP-Win32
-; driver, each installed by different apps, can coexist
-; on the same machine if you follow these guidelines.
-; NOTE: these instructions assume you are editing the
-; generated OemWin2k.inf file, not the source
-; OemWin2k.inf.in file which is preprocessed by winconfig
-; and uses macro definitions from settings.in.
-;
-; (1) Rename all tapXXXX instances in this file to
-;     something different (use at least 5 characters
-;     for this name!)
-; (2) Change the "!define TAP" definition in openvpn.nsi
-;     to match what you changed tapXXXX to.
-; (3) Change TARGETNAME in SOURCES to match what you
-;     changed tapXXXX to.
-; (4) Change TAP_COMPONENT_ID in common.h to match what
-;     you changed tapXXXX to.
-; (5) Change SZDEPENDENCIES in service.h to match what
-;     you changed tapXXXX to.
-; (6) Change DeviceDescription and Provider strings.
-; (7) Change PRODUCT_STRING in constants.h to what you
-;     set DeviceDescription to.
