2776209e49 portlist: don't depend on osexec package on ios, even if it's unused
Continuation of 5bb14c07dc.

The earlier commit provided the space savings (as the linker could see
through that osexec was unused at runtime), but it didn't clean up the
dep graph (from go list -json or godepgraph).

This removes the netstat.go file from the build too, just so the dep list
looks more reasonable.

5bb14c07dc portlist: don't depend on tempfork/osexec on iOS, saves 90KB
This gives us 90KB more of memory on iOS, as it shrinks the
NetworkExtension binary by 90KB.

The netstat binary isn't available in the network extension anyway, so
no point pulling in the osexec package which'll just fail to find
netstat anyway.

e19287f60f wgengine/magicsock: fix Conn docs type reference
The docs on magicsock.Conn stated that they implemented the
wireguard/device.Bind interface, yet this type does not exist. In
reality, the Conn type implements the wireguard/conn.Bind interface.

I also fixed a small typo in the same file.

febdac0499 tstime: write Parse3339 parse that doesn't use time.Parse
It doesn't allocate and it's half the time of time.Parse (which
allocates), and 2/3rds the time of time.ParseInLocation (which
doesn't).

Go with a UTC time:

BenchmarkGoParse3339/Z-8                 2200995               534 ns/op               0 B/op          0 allocs/op
BenchmarkGoParse3339/Z-8                 2254816               554 ns/op               0 B/op          0 allocs/op
BenchmarkGoParse3339/Z-8                 2159504               522 ns/op               0 B/op          0 allocs/op

Go allocates with a "-08:00" suffix instead of ending in "Z":

BenchmarkGoParse3339/TZ-8                1276491               884 ns/op             144 B/op          3 allocs/op
BenchmarkGoParse3339/TZ-8                1355858               942 ns/op             144 B/op          3 allocs/op
BenchmarkGoParse3339/TZ-8                1385484               911 ns/op             144 B/op          3 allocs/op

Go doesn't allocate if you use time.ParseInLocation, but then you need
to parse the string to find the location anyway, so might as well go
all the way (below).

BenchmarkGoParse3339InLocation-8         1912254               597 ns/op               0 B/op          0 allocs/op

d503dee6f1 tstime: add new package for time utilities, starting with Parse3339
Go's time.Parse always allocates a FixedZone for time strings not in
UTC (ending in "Z"). This avoids that allocation, at the cost of
adding a cache.

64334143a1 tsweb: rename Handler to ReturnHandler
The name's been bugging me for a long time.

I liked neither the overlap between tsweb.Handler and http.Handler,
nor the name "ServeHTTPErr" which sounds like it's an error being
returned, like it's an error handler and not sometimes a happy path.

0590ad68be controlclient, ipn: adjust tests for authURL semantic changes
The tests cheat at filling out web forms by directly POSTing to
the target. The target for authURLs has changed slightly, the base
authURL now redirects the user to the login page.

Additionally, the authURL cycle now checks the cookie is set
correctly, so we add cookie jars where necessary to pass the
cookie through.
