- Does not function with controllers that don't produce continuous joystick events on hold, as testing unfortunately made clear.
- The entire thing would need to be rewritten to make up for that, and I don't have the time to invest that kind of energy into version 1.
- An unreliable feature is worse than no feature at all.

Ported and flattened from Sal's work on the internal repository

This reverts commit 44eeb3a0.

# Conflicts:

* Rename `Look Up/Down` to `Spec. Look Up/Down` to disambiguate from `Look Backward`
* Make it support multiplayer replay recording save request too

- They're binary inputs as processed by the game.
- A mechanism for binary inputs with no deadzone is already used for item and drift.
- Generally bound to triggers, not the stick.
- SDL still has a minimum deadzone, so won't fire endlessly.

* For left stick up/down/left/right input, allow holding a direction down to move continuously in a direction at a rate of 7 steps per second per axis
* Now supports accel axis being used for the Enter key/"accept" in menus, to mirror how an accel BUTTON bind will be used as an Enter event.

Also, make the I_GetJoystickEvents functions match each other

If the client has caught up to the server -- say, during a wipe -- make GetLag return a ping of zero

Should fix the momentarily large ping bug.

* If `kartvoterulechanges` is set to `Always`, the third option is always the opposite gametype, even if Encore is unlocked - that will now be present on the second option instead.
    * This is both for consistancy with having Encore inaccessible on your gamedata, and a response to community feedback.
* The `kartencore` cvar being turned on will now be reflected in gametype rule changes from Battle to Race. This plugs one last hole in its area of effect for Race tracks.

This appears to be a long-time bug that exists upstream too, but nobody even knew about it before the MS rules alert made it clear this was actually happening!

Worth doing now that that's been merged into next. Also pulls in a
little bit of master.
