If the --key-file output filename ends in ".pfx" or ".p12", use pkcs12
format.
This might not be working entirely correctly yet but might be enough for
others to help out or experiment.

Noticed when testing FUS on tailscale-on-macOS, that routing would break
completely when switching between profiles. However, it would start working
again when going back to the original profile tailscaled started with.
Turns out that if we change the addrs on the interface we need to remove and readd
all the routes.

Map is a concurrent safe map that is a trivial wrapper
over a Go map and a sync.RWMutex.
It is optimized for use-cases where the entries change often,
which is the opposite use-case of what sync.Map is optimized for.
The API is patterned off of sync.Map, but made generic.

Numerous issues have been filed concerning an inability to install and run
Tailscale headlessly in unattended mode, particularly after rebooting. The
server mode `Prefs` stored in `server-state.conf` were not being updated with
`Persist` state once the node had been succesfully logged in.
Users have been working around this by finagling with the GUI to make it force
a state rewrite. This patch makes that unnecessary by ensuring the required
server mode state is updated when prefs are updated by the control client.

There is a finite limit to the maximum message size that logtail can upload.
We need to make sure network logging messages remain under this size.
These constants allow us to compute the maximum number of ConnectionCounts
we can buffer before we must flush.

cmd/viewer couldn't deal with that map-of-map. Add a wrapper type
instead, which also gives us a place to add future stuff.

All IPv6 packets for the self address were doing netip.Prefix.Contains
lookups.
If if we know they're for a self address (which we already previously
computed and have sitting in a bool), then they can't be for a 4via6
range.

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.

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.

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.

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.
