Tom DNetto c08cf2a9c6 all: declare & plumb IPv6 masquerade address for peer
This PR plumbs through awareness of an IPv6 SNAT/masquerade address from the wire protocol
through to the low-level (tstun / wgengine). This PR is the first in two PRs for implementing
IPv6 NAT support to/from peers.

A subsequent PR will implement the data-plane changes to implement IPv6 NAT - this is just plumbing.

Maisem Ali 19a9d9037f tailcfg: add NodeCapMap
Like PeerCapMap, add a field to `tailcfg.Node` which provides
a map of Capability to raw JSON messages which are deferred to be
parsed later by the application code which cares about the specific
capabilities. This effectively allows us to prototype new behavior
without having to commit to a schema in tailcfg, and it also opens up
the possibilities to develop custom behavior in tsnet applications w/o
having to plumb through application specific data in the MapResponse.

James Tucker e7727db553 tailcfg: add DNS address list for IsWireGuardOnly nodes
Tailscale exit nodes provide DNS service over the peer API, however
IsWireGuardOnly nodes do not have a peer API, and instead need client
DNS parameters passed in their node description.

For Mullvad nodes this will contain the in network 10.64.0.1 address.

To record wether user is using iptables or nftables after we add support to nftables on linux, we
are adding a field FirewallMode to NetInfo in HostInfo to reflect what firewall mode the host is
running, and form metrics. The information is gained from a global constant in hostinfo.go. We
set it when selection heuristic made the decision, and magicsock reports this to control.

Charlotte Brandhorst-Satzkorn 3417ddc00c tailcfg: add location field to hostinfo
This change adds Location field to HostInfo.
Location contains the option for a Country, CountryCode, City, CityCode
and a Priority. Neither of these fields are populated by default.

The Priority field is used to determine the priority an exit
node should be given for use, if the field is set. The higher the value
set, the higher priority the node should be given for use.

Brad Fitzpatrick 45a3de14a6 cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support
As noted in #5617, our documented method of blocking log.tailscale.io
DNS no longer works due to bootstrap DNS.

Instead, provide an explicit flag (--no-logs-no-support) and/or env
variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher
uploads. It also sets a bit on Hostinfo to say that the node is in that
mode so we can end any support tickets from such nodes more quickly.

This does not yet provide an easy mechanism for users on some
platforms (such as Windows, macOS, Synology) to set flags/env. On
Linux you'd used /etc/default/tailscaled typically. Making it easier
to set flags for other platforms is tracked in #5114.
