input: don't deliver mouse events if mouse area is not set

This caused the OSC to be always visible at startup on X11:
- EnterNotify event send a mouse event to input.c
- OSC has not completely initialized yet, and no mouse area is set
- mouse event is dispatched to "showhide" OSC section
- OSC becomes visible, regardless of mouse position

Fix this by treating the mouse area as empty if it's not set, instead of
infinite as it was before this commit. This means an input section must
set a mouse area to receive mouse events at all. We also have to change
the default section to receive mouse events with the new behavior.

Also, if MOUSE_MOVE is unmapped (or mapped to something that doesn't
parse), and produces no command, the mouse position wouldn't be updated
(because the mouse position is bound to input commands), so we have to
generate a dummy command in this case.

(This matters only for the OSC, On Screen Controller, which isn't merged
yet, so these changes shouldn't have much effect right now.)
