These aren't particularly performance critical,
but since I have an optimization pending for them,
it's worth having a corresponding benchmark.

This benchmark is far from perfect: It mixes together
client and server. Still, it provides a starting point
for easy profiling.

iOS doesn't let you run subprocesses,
which means we can't use netstat to get routing information.
Instead, use syscalls and grub around in the results.
We keep the old netstat version around,
both for use in non-cgo builds,
and for use testing the syscall-based version.
Note that iOS doesn't ship route.h,
so we include a copy here from the macOS 10.15 SDK
(which is itself unchanged from the 10.14 SDK).
I have tested manually that this yields the correct
gateway IP address on my own macOS and iOS devices.
More coverage would be most welcome.
