Brad Fitzpatrick 82edf94df7 ipn/ipnlocal: make IPv6 OS routes be a single /48 for our ULA space
And if we have over 10,000 CGNAT routes, just route the entire
CGNAT range. (for the hello test server)

Fixes #1450

Brad Fitzpatrick 625c413508 ipn/ipnlocal: fix another regression from link monitoring refactor
Prior to e3df29d488, the Engine.SetLinkChangeCallback fired
immediately, even if there was no change. The ipnlocal code apparently
depended on that, and it broke integration tests (which live in
another repo). So mimic the old behavior and call the ipnlocal
callback immediately at init.

Brad Fitzpatrick e3df29d488 wgengine{,/monitor}: move interface state fetching/comparing to monitor
Gets it out of wgengine so the Engine isn't responsible for being a
callback registration hub for it.

This also removes the Engine.LinkChange method, as it's no longer
necessary.  The monitor tells us about changes; it doesn't seem to
need any help. (Currently it was only used by Swift, but as of
14dc790137 we just do the same from Go)

Brad Fitzpatrick 38dc6fe758 cmd/tailscaled, wgengine: remove --fake, replace with netstack
And add a --socks5-server flag.

And fix a race in SOCKS5 replies where the response header was written
concurrently with the copy from the backend.

David Anderson 2404c0ffad ipn/ipnlocal: only filter out default routes when computing the local wg config.
UIs need to see the full unedited netmap in order to know what exit nodes they
can offer to the user.

David Anderson e86b39b73f ipn/ipnlocal: don't short-circuit default route filtering.
If no exit node is specified, the filter must still run to remove
offered default routes from all peers.

Brad Fitzpatrick ddfcc4326c types/persist: split controlclient.Persist into a small leaf package
This one alone doesn't modify the global dependency map much
(depaware.txt if anything looks slightly worse), but it leave
controlclient as only containing NetworkMap:

bradfitz@tsdev:~/src/tailscale.com/ipn$ grep -F "controlclient." *.go
backend.go:     NetMap        *controlclient.NetworkMap // new netmap received
fake_test.go:   b.notify(Notify{NetMap: &controlclient.NetworkMap{}})
fake_test.go:   b.notify(Notify{NetMap: &controlclient.NetworkMap{}})
handle.go:      netmapCache       *controlclient.NetworkMap
handle.go:func (h *Handle) NetMap() *controlclient.NetworkMap {

Once that goes into a leaf package, then ipn doesn't depend on
controlclient at all, and then the client gets smaller.
