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.

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.

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.
