tun: openbsd: check for interface already being up
...
In some cases, we operate on an already-up interface, or the user brings
up the interface before we start monitoring. For those situations, we
should first check if the interface is already up.
This still technically races between the initial check and the start of
the route loop, but fixing that is a bit ugly and probably not worth it
at the moment.

DeleteAllInterfaces() didn't check if SPDRP_DEVICEDESC == "WireGuard
Tunnel". It deleted _all_ Wintun adapters, not just WireGuard's.
Furthermore, the DeleteAllInterfaces() was upgraded into a new function
called DeleteMatchingInterfaces() for selectively deletion. This will
be used by WireGuard to clean stale Wintun adapters.

- expandString() >> toString() and extend to support REG_MULTI_SZ
(to return first value of REG_MULTI_SZ). Furthermore, doing our own
UTF-16 to UTF-8 conversion works around a bug in windows/registry's
GetStringValue() non-zero terminated string handling.
- Provide toInteger() analogous to toString()
- GetStringValueWait() tolerates and reads REG_MULTI_SZ too now. It
returns REG_MULTI_SZ[0], making GetFirstStringValueWait() redundant.
