The suggested exit node is currently only calculated during a localAPI request.
For older UIs, this wasn't a bad choice - we could just fetch it on-demand when a menu
presented itself. For newer incarnations however, this is an always-visible field
that needs to react to changes in the suggested exit node's value.
This change recalculates the suggested exit node ID on netmap updates and
broadcasts it on the IPN bus. The localAPI version of this remains intact for the
time being.

I merged 5cae7c51bf (removing Notify.BackendLogID) and 93db503565
(adding another reference to Notify.BackendLogID) that didn't have merge
conflicts, but didn't compile together.
This removes the new reference, fixing the build.

Limit spamming GUIs with boring updates to once in 3 seconds, unless
the notification is relatively interesting and the GUI should update
immediately.
This is basically @barnstar's #14119 but with the logic moved to be
per-watch-session (since the bit is per session), rather than
globally. And this distinguishes notable Notify messages (such as
state changes) and makes them send immediately.
