74a6f97b7a wg: genkey: account for short reads of /dev/urandom 
Apparently Haiku has a misbehaving /dev/urandom.

While we're at it, simplify the function signature to completely succeed
or completely fail and make sure the caller checks the result.

3ac679e7a1 keygen-html: bring back pure javascript implementation 
This reverts commit 9d5baf7d1d14ca7eb0852b41566330259229d489.

Benoît Viguier has proofs that values will stay well within 2^53. We
also have an improved carry function that's much simpler.

599b84fbd1 wg: don't fail if a netlink interface dump is inconsistent 
Netlink returns NLM_F_DUMP_INTR if the set of all tunnels changed
during the dump. That's unfortunate, but is pretty common on busy
systems that are adding and removing tunnels all the time. Rather
than retrying, potentially indefinitely, we just work with the
partial results.
