Maisem Ali 4669e7f7d5 cmd/containerboot: add iptables based MSS clamping for ingress/egress proxies
In typical k8s setups, the MTU configured on the eth0 interfaces is typically 1500 which
results in packets being dropped when they make it to proxy pods as the tailscale0 interface
has a 1280 MTU.

As the primary use of this functionality is TCP, add iptables based MSS clamping to allow
connectivity.

Maisem Ali 19a9d9037f tailcfg: add NodeCapMap
Like PeerCapMap, add a field to `tailcfg.Node` which provides
a map of Capability to raw JSON messages which are deferred to be
parsed later by the application code which cares about the specific
capabilities. This effectively allows us to prototype new behavior
without having to commit to a schema in tailcfg, and it also opens up
the possibilities to develop custom behavior in tsnet applications w/o
having to plumb through application specific data in the MapResponse.

This adds a new RawMessage type backed by string instead of the

Brad Fitzpatrick 0d991249e1 types/netmap: remove NetworkMap.{Addresses,MachineStatus}
And convert all callers over to the methods that check SelfNode.

Now we don't have multiple ways to express things in tests (setting
fields on SelfNode vs NetworkMap, sometimes inconsistently) and don't
have multiple ways to check those two fields (often only checking one
or the other).

a new "tailscale debug control-knobs" which by itself might be useful
for future debugging.

If the user's running "go test" by hand, no need to spam stderr with

on actual failure, or verbose mode) which is enough to tell users it's
known flaky. Stderr OTOH always prints out and is distracting to
manual "go test" users.

To repro, add this to tstest/integration:

        time.Sleep(3 * time.Second)
        os.Exit(1)

    }

Those three seconds let the other parallel tests (with all their
tailscaled child processes) start up and start running their tests,
but then we violently os.Exit(1) the test driver and all the children
were kept alive (and were spinning away, using all available CPU in
gvisor scheduler code, which is a separate scary issue)
