We already present a health warning about this, but it is easy to miss
on a server when blackholing traffic makes it unreachable.
In addition to a health warning, present a risk message when exit node
is enabled.
Example:
```
$ tailscale up --exit-node=lizard
The following issues on your machine will likely make usage of exit nodes impossible:
- interface "ens4" has strict reverse-path filtering enabled
- interface "tailscale0" has strict reverse-path filtering enabled
Please set rp_filter=2 instead of rp_filter=1; see https://github.com/tailscale/tailscale/issues/3310
To skip this warning, use --accept-risk=linux-strict-rp-filter

This commit adds a new type to magicsock, epAddr, which largely ends up
replacing netip.AddrPort in packet I/O paths throughout, enabling
Geneve encapsulation over UDP awareness.
The conn.ReceiveFunc for UDP has been revamped to fix and more clearly
distinguish the different classes of packets we expect to receive: naked
STUN binding messages, naked disco, naked WireGuard, Geneve-encapsulated
disco, and Geneve-encapsulated WireGuard.
Prior to this commit, STUN matching logic in the RX path could swallow
a naked WireGuard packet if the keypair index, which is randomly
generated, happened to overlap with a subset of the STUN magic cookie.

In 1.84 we made 'tailscale set'/'tailscale up' error out if duplicate
command line flags are passed.
This broke some container configurations as we have two env vars that
can be used to set --accept-dns flag:
- TS_ACCEPT_DNS- specifically for --accept-dns
- TS_EXTRA_ARGS- accepts any arbitrary 'tailscale up'/'tailscale set'
flag.
We default TS_ACCEPT_DNS to false (to make the container behaviour more
declarative), which with the new restrictive CLI behaviour resulted in
failure for users who had set --accept-dns via TS_EXTRA_ARGS as the flag would be
provided twice.
This PR re-instates the previous behaviour by checking if TS_EXTRA_ARGS
contains --accept-dns flag and if so using its value to override TS_ACCEPT_DNS.

Using WINHTTP_AUTOPROXY_ALLOW_AUTOCONFIG on Windows versions older than Windows 10 1703 (build 15063)
is not supported and causes WinHttpGetProxyForUrl to fail with ERROR_INVALID_PARAMETER. This results in failures
reaching the control on environments where a proxy is required.
We use wingoes version detection to conditionally set the WINHTTP_AUTOPROXY_ALLOW_AUTOCONFIG flag
on Windows builds greater than 15063.
While there, we also update proxy detection to use WINHTTP_AUTO_DETECT_TYPE_DNS_A, as DNS-based proxy discovery
might be required with Active Directory and in certain other environments.

We now keep track of any dns configurations which we could not
compile. This gives RecompileDNSConfig a configuration to
attempt to recompile and apply when the OS pokes us to indicate
that the interface dns servers have changed/updated. The manager config
will remain unset until we have the required information to compile
it correctly which should eliminate the problematic SERVFAIL
responses (especially on macOS 15).
This also removes the missingUpstreamRecovery func in the forwarder
which is no longer required now that we have proper error handling
and recovery manager and the client.
