net/dns: replace AuthoritativeSuffixes with nil Route entries.
...
This leads to a cleaner separation of intent vs. implementation
(Routes is now the only place specifying who handles DNS requests),
and allows for cleaner expression of a configuration that creates
MagicDNS records without serving them to the OS.

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.
