Denton Gentry 90351e7392 backend: Send DNS config through CallbackRouter.
Using NewNoopManager avoided the errors from trying to overwrite
/etc/resolv.conf, but still didn't fully work. Route DNS config
through the CallbackRouter.

Fixes https://github.com/tailscale/tailscale/issues/1956

Denton Gentry ec8133a972 backend: use dns.NewNoopManager.
Android updates its DNS config in updateTUN() when in response
to several different channels from the backend.

There is not an Android-specific NewOSConfigurator, we end
up pulling in the Linux NewOSConfigurator:
https://github.com/tailscale/tailscale/blob/main/net/dns/manager_linux.go

The Linux DNS manager expects to be able to write to /etc/resolv.conf,
which does not work on Android and causes errors in updating DNS config.

Instead, allocate dns.NewNoopManager to disable the DNS manager, and
rely on the updateTUN() code to handle DNS.

Elias Naur b151de039b cmd/tailscale: simplify non-blocking coalescing channels
Three variables are used everywhere a single non-blocking producer sends
values where only the latest is relevant:

    var (
	    mu sync.Mutex
	    latest T
	    notify = make(chan struct{}, 1)
    )

By draining the notification channel before sending through it, we
can simplify to just one channel:

    latest = make(chan T, 1)

Thanks to Chris Waldon for showing me this neat trick.

Elias Naur 9db851a113 cmd/tailscale: notify user when VPN access is denied
When tailscale starts, any other active VPN service is automatically closed by the system.
However, if the other VPN service is configured to be always-on, we will be denied access
to set up a VPN. The user may not realize this case, so this change adds a notification
when we're denied access.

The failure mode is identical to the user denying access tthrough the system dialog
shown first time Tailscale starts, so the notification also mentions that case.

Elias Naur 943bded910 cmd/tailscale: don't duplicate log output
logtail.Log by default writes log output to stderr, but stderr is taken over by
filch's ReplaceStderr, resulting in duplicate logs sent to Tailscale.
ReplaceStderr is useful for capturing stack dumps from panics.

Configure logtail to route logs to the Android logger, which stops the
duplicate logging and replaces an existing MultiWriter setup for the same
purpose.

Reduce the scope of the logtail logger while here.
