Also make IPPrefixSliceOf use Slice[netaddr.IPPrefix] as it also
provides additional functions besides the standard ones provided by
Slice[T].

We need to capture some tailnet-related information for some Docker
features we're building. This exposes the tailnet name and MagicDNS
information via `tailscale status --json`.

It's been a bunch of releases now since the TailscaleIPs slice
replacement was added.

And in the process, fix the related confusing error messages from
pinging your own IP or hostname.

magicsock makes multiple calls to Now per packet.
Move to mono.Now. Changing some of the calls to
use package mono has a cascading effect,
causing non-per-packet call sites to also switch.

Needed for the "up checker" to map back from exit node stable IDs (the
ipn.Prefs.ExitNodeID) back to an IP address in error messages.
But also previously requested so people can use it to then make API
calls. The upcoming "tailscale admin" subcommand will probably need it
too.

For discovery when an explicit hostname/IP is known. We'll still
also send it via control for finding peers by a list.

And move a couple other types down into leafier packages.
Now cmd/tailscale doesn't bring in netlink, magicsock, wgengine, etc.

* show DNS name over hostname, removing domain's common MagicDNS suffix.
only show hostname if there's no DNS name.
but still show shared devices' MagicDNS FQDN.
* remove nerdy low-level details by default: endpoints, DERP relay,
public key. They're available in JSON mode still for those who need
them.
* only show endpoint or DERP relay when it's active with the goal of
making debugging easier. (so it's easier for users to understand
what's happening) The asterisks are gone.
* remove Tx/Rx numbers by default for idle peers; only show them when
there's traffic.
* include peers' owner login names
* add CLI option to not show peers (matching --self=true, --peers= also
defaults to true)
* sort by DNS/host name, not public key
* reorder columns
For example:
$ tailscale ping -h

There's a lot of confusion around what tailscale status shows, so make it better:
show region names, last write time, and put stars around DERP too if active.
Now stars are always present if activity, and always somewhere.
