108c37a056 wintun: don't run HrRenameConnection in separate thread
It's very slow, but unfortunately we haven't a choice. NLA needs this to
have completed.

da61947ec3 tun: windows: mitigate infinite loop in Flush()
It's possible that for whatever reason, we keep returning EOF, resulting
in repeated close/open/write operations, except with empty packets.

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.

bb42ec7d18 tun: freebsd: work around numerous kernel panics on shutdown
There are numerous race conditions. But even this will crash it:

while true; do ifconfig tun0 create; ifconfig tun0 destroy; done

It seems like LLv6 is related, which we're not using anyway, so
explicitly disable it on the interface.

5811447b38 setupapi: Revise DrvInfoDetailData struct size calculation
Go adds trailing padding to DrvInfoDetailData struct in GOARCH=386 which
