- Make tun.CreateTUN() quit when foreign interface found before
attempting to create a Wintun interface with a duplicate name.
Creation is futile.

wintun: registry: revise value reading
...
- Make getStringValueRetry() reusable for reading any value type. This
merges code from GetIntegerValueWait().
- 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.
