Josh Bleecher SnyderandJosh 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.

Josh Bleecher SnyderandJosh Bleecher Snyder 138055dd70 tstest/natlab: use net.ErrClosed instead of a new error 
Upstream wireguard-go decided to use errors.Is(err, net.ErrClosed)
instead of checking the error string.

It also provided an unsafe linknamed version of net.ErrClosed
for clients running Go 1.15. Switch to that.

This reduces the time required for the wgengine/magicsock tests
on my machine from ~35s back to the ~13s it was before

Josh Bleecher SnyderandJosh Bleecher Snyder 18471a8792 ipn: close logger at the end of TestLocalLogLines 
If any goroutine continues to use the logger in TestLocalLogLines
after the test finishes, the test panics.

The culprit for this was wireguard-go; the previous commit fixed that.
This commit adds suspenders: When the test is done, make logging calls
into no-ops.

David AndersonandDave Anderson 45578b47f3 tstest/natlab: refactor PacketHandler into a larger interface. 
The new interface lets implementors more precisely distinguish
local traffic from forwarded traffic, and applies different
forwarding logic within Machines for each type. This allows
Machines to be packet forwarders, which didn't quite work
with the implementation of Inject.
