We still include them directly in the controlclient network map
just where we have been. Client plumbing we can do later.

David Crawshaw d417be6a4b controlclinet: clone filter.MatchAllowAll
This avoids a non-obvious data race, where the JSON decoder ends
up creating do-nothing writes into global variables.

David Crawshaw c576a57067 wgengine: avoid holding any locks during HandshakeDone
Because wgLock is held while some wireguard-go methods run,
trying to hold wgLock during HandshakeDone potentially creates
lock cycles between wgengine and internals of wireguard-go.

Arguably wireguard-go should call HandshakeDone in a new goroutine,
but until its API promises that, don't make any assumptions here.

Maybe for #110.

David Anderson 78654ee1bd cmd/tailscale: switch to an ffcli based CLI.
Two commands for now, `up` and `netcheck`. The commands and the flags they take
will change a bunch in the future, but this is good enough to launch on parity
with relaynode.

Brad Fitzpatrick 14559340ee Start of netcheck package & including network state in Hostinfo.
* adds new packet "netcheck" to do the checking of UDP, IPv6, and
  nearest DERP server, and the Report type for all that (and more
  in the future, probably pulling in danderson's natprobe)
* new tailcfg.NetInfo type
* cmd/tailscale netcheck subcommand (tentative name, likely to
  change/move) to print out the netcheck.Report.
