Josh Bleecher Snyder 25df067dd0 all: adapt to opaque netaddr types
This commit is a mishmash of automated edits using gofmt:

gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w .
gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w .

gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w .
gofmt -r 'a.IP.As16 -> a.IP().As16' -w .
gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w .
gofmt -r 'a.IP.As4 -> a.IP().As4' -w .
gofmt -r 'a.IP.String -> a.IP().String' -w .

And regexps:

\w*(.*)\.Port = (.*)  ->  $1 = $1.WithPort($2)
\w*(.*)\.IP = (.*)  ->  $1 = $1.WithIP($2)

And lots of manual fixups.

Denton Gentry 35ab4020c7 wgengine/monitor: Linux fall back to polling
Google Cloud Run does not implement NETLINK_ROUTE RTMGRP.
If initialization of the netlink socket or group membership
fails, fall back to a polling implementation.

Brad Fitzpatrick 7461dded88 wgengine/monitor: on unsupported platforms, use a polling implementation
Not great, but lets people working on new ports get going more quickly
without having to do everything up front.

As the link monitor is getting used more, I felt bad having a useless
implementation.

Brad Fitzpatrick ce1b52bb71 wgengine/monitor: fix other potential crashes on Linux
Never return "nil, nil" anymore. The caller expected a usable
interface now. I missed some of these earlier.

Also, handle address deletion now.
