tsnet/tsnet: clear ipn.ServeConfig on Up for tsnet apps (#7534)
We persist the ServeConfig, even for tsnet apps. It's quite possible for
the ServeConfig to be out of step with the code. Example: If you run
`ListenFunnel` then later turn it off, the ServeConfig will still show
it enabled, the admin console will show it enabled, but the packet
handler will reject the packets.

Workaround by clearing the ServeConfig in `tsnet.Up`

Maisem Ali b797f773c7 ipn/ipnlocal: add support for funnel in tsnet
Previously the part that handled Funnel connections was not
aware of any listeners that tsnet.Servers might have had open
so it would check against the ServeConfig and fail.

Adding a ServeConfig for a TCP proxy was also not suitable in this
scenario as that would mean creating two different listeners and have
one forward to the other, which really meant that you could not have
funnel and tailnet-only listeners on the same port.

This also introduces the ipn.FunnelConn as a way for users to identify
whether the call is coming over funnel or not. Currently it only holds
the underlying conn and the target as presented in the "Tailscale-Ingress-Target"
header.

David Crawshaw 387b68fe11 tsnet: generalize loopback listener to include SOCKS5
Some languages do not give you any useful access to the sockets
underlying their networking packages. E.g. java.net.http.HttpClient
provides no official access to its dialing logic.

...but everyone supports proxies. So add a SOCKS5 proxy on the listener
we are already running.

(The function being revamped is very new,
I only added it in the last week and it wasn't part of any release,
so I believe it is fine to redo its function signature.)

Tom DNetto 9e77660931 net/tstun,wgengine/{.,netstack}: handle UDP magicDNS traffic in netstack
This change wires netstack with a hook for traffic coming from the host
into the tun, allowing interception and handling of traffic to quad-100.

With this hook wired, magicDNS queries over UDP are now handled within
netstack. The existing logic in wgengine to handle magicDNS remains for now,
but its hook operates after the netstack hook so the netstack implementation
takes precedence. This is done in case we need to support platforms with
netstack longer than expected.

Brad Fitzpatrick c37af58ea4 net/tsdial: move more weirdo dialing into new tsdial package, plumb
Not done yet, but this move more of the outbound dial special casing
from random packages into tsdial, which aspires to be the one unified
place for all outbound dialing shenanigans.

Then this plumbs it all around, so everybody is ultimately
holding on to the same dialer.

As of this commit, macOS/iOS using an exit node should be able to
reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt
to stay within the Network Extension.

A number of steps remain, including but limited to:

* move a bunch more random dialing stuff

* make netstack-mode tailscaled be able to use exit node's DNS proxy,
  teaching tsdial's resolver to use it when an exit node is in use.

Josh 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.
