ef23100a4f wintun: set friendly a bit better
This is still wrong, but NETSETUPPKEY_Driver_FriendlyName seems a bit
tricky to use.

1ff37e2b07 wintun: merge opening device registry key
This also introduces waiting for key to appear on initial access.

See if this resolves the issue caused by HDD power-up delay resulting in
failure to create the adapter.

6a0a3a5406 wintun: revise GetInterface()
- Make foreign interface found error numeric to ease condition
  detection.
- Update GetInterface() documentation.
- Make tun.CreateTUN() quit when foreign interface found before
  attempting to create a Wintun interface with a duplicate name.
  Creation is futile.

6c1b66802f 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.

46dbf54040 wintun: don't retry when not creating
The only time we're trying to counteract the race condition is when
we're creating a driver. When we're simply looking up all drivers, it
doesn't make sense to retry.
