acf5839dd2 wgengine/netstack: add tests for shouldProcessInbound
Inspired by #6235, let's explicitly test the behaviour of this function
to ensure that we're not processing things we don't expect to.

abfdcd0f70 wgengine/netstack: fix shouldProcessInbound peerapi non-SYN handling
It was eating TCP packets to peerapi ports to subnet routers.  Some of
the TCP flow's packets went onward, some got eaten.  So some TCP flows
to subnet routers, if they used an unfortunate TCP port number, got
broken.

9be8d15979 ipn/localapi: refactor some cert code in prep for a move
I want to move the guts (after the HTTP layer) of the certificate
fetching into the ipnlocal package, out of localapi.

As prep, refactor a bit:

* add a method to do the fetch-from-cert-or-as-needed-with-refresh,
  rather than doing it in the HTTP hander

* convert two methods to funcs, taking the one extra field (LocalBackend)
  then needed from their method receiver. One of the methods needed
  nothing from its receiver.

This will make a future change easier to reason about.

847a8cf917 api.md: make it clearer where to get the tailnet name in API calls
We added the tailnet organization name to to the settings page with
tailscale/corp#6977, but the docs were not updated to reflect this.
We later also changed "tailnet name" to refer to the MagicDNS hostname
(tailscale/corp#7537), which further confuses things (see https://stackoverflow.com/questions/74132318).

Make it slightly clearer what is the expected value for tailnet names in
API calls and how to get it.

db2cc393af util/dirwalk, metrics, portlist: add new package for fast directory walking
This is similar to the golang.org/x/tools/internal/fastwalk I'd
previously written but not recursive and using mem.RO.

The metrics package already had some Linux-specific directory reading
code in it. Move that out to a new general package that can be reused
by portlist too, which helps its scanning of all /proc files:

21ef7e5c35 portlist: add macOS osImpl, finish migration to new style
Previously:

* 036f70b7b4 for linux
* 35bee36549 for windows

This does macOS.

And removes all the compat code for the old style. (e.g. iOS, js are
no longer mentioned; all platforms without implementations just
default to not doing anything)

One possible regression is that platforms without explicit
implementations previously tried to do the "netstat -na" style to get
open ports (but not process names). Maybe that worked on FreeBSD and
OpenBSD previously, but nobody ever really tested it. And it was kinda
useless without associated process names. So better off removing those
for now until they get a good implementation.

76904b82e7 cmd/containerboot: PID1 for running tailscaled in a container.
This implements the same functionality as the former run.sh, but in Go
and with a little better awareness of tailscaled's lifecycle.

Also adds TS_AUTH_ONCE, which fixes the unfortunate behavior run.sh had
where it would unconditionally try to reauth every time if you gave it
an authkey, rather than try to use it only if auth is actually needed.
This makes it a bit nicer to deploy these containers in automation, since
you don't have to run the container once, then go and edit its definition
to remove authkeys.

wgengine/netlog: preserve Tailscale addresses for exit traffic (#6165)
Exit node traffic is aggregated to protect the privacy
of those using an exit node. However, it is reasonable to
at least log which nodes are making most use of an exit node.

For a node using an exit node,
the source will be the taiscale IP address of itself,
while the destination will be zeroed out.

For a node that serves as an exit node,
the source will be zeroed out,
while the destination will be tailscale IP address
of the node that initiated the exit traffic.
