Implement `tailscale update` on FreeBSD. This is much simpler than other
platforms because `pkg rquery` lets us get the version in their repos
without any extra parsing.

Define PeerCapabilty and PeerCapMap as the new way of sending down
inter-peer capability information.
Previously, this was unstructured and you could only send down strings
which got too limiting for certain usecases. Instead add the ability
to send down raw JSON messages that are opaque to Tailscale but provide
the applications to define them however they wish.
Also update accessors to use the new values.

Similar to Arch support, use the latest version info from the official
`apk` repo and don't offer explicit track or version switching.
Add detection for Alpine Linux in version/distro along the way.

One is a straight "I forgot how to Go" bug, the others are semantic
mismatches with the main implementation around masking the prefixes
passed to insert/delete.

This is a prerequisite for path compression, so that insert/delete
can determine when compression occurred.

If the connection provided to sftp.NewServer is closed,
Serve returns the io.EOF error verbatim from io.Reader.Read.
This is an odd error since this is an expected situation,
so we manually ignore io.EOF.
This is somewhat buggy since the sftp package itself
incorrectly reports io.EOF in cases where it should actually
be reporting io.ErrUnexpectedEOF.
See https://github.com/pkg/sftp/pull/554 which patches Serve to
return nil on clean closes and fixes buggy uses of io.ReadFull.

The util/linuxfw/iptables.go had a bunch of code that wasn't yet used
(in prep for future work) but because of its imports, ended up
initializing code deep within gvisor that panicked on init on arm64
systems not using 4KB pages.
This deletes the unused code to delete the imports and remove the
panic. We can then cherry-pick this back to the branch and restore it
later in a different way.
A new test makes sure we don't regress in the future by depending on
the panicking package in question.

Having `127.0.0.53` is not the only way to use `systemd-resolved`. An
alternative way is to enable `libnss_resolve` module, which seems to now
be used by default on Debian 12 bookworm.

Arch version of tailscale is not maintained by us, but is generally
up-to-date with our releases. Therefore "tailscale update" is just a
thin wrapper around "pacman -Sy tailscale" with different flags.

Even on macOS when Tailscale was installed via the App Store, we can check for
and even install new versions if people ask explicitly. Also, warn if App Store
AutoUpdate is not turned on.

In late 2022 a subtle but crucial part of documentation was added to ed25519.Verify: It
will panic if len(publicKey) is not [PublicKeySize].

This change catches that error so it won't lead to a panic.

Allow inline CSS for debug handlers to make prototyping easier. These
are generally not accessible to the public and the small risk of CSS
injection via user content seems acceptable.
Also allow form submissions on the same domain, instead of banning all
forms. An example of such form is

will use nftables to manage firewall rules.

If the absolute value of the difference between the current
PreferredDERP's latency and the best latency is <= 10ms, don't change
it and instead prefer the previous value.
This is in addition to the existing hysteresis that tries to remain
on the previous DERP region if the relative improvement is small, but
handles nodes that have low latency to >1 DERP region better.
