use updatemons as handler for output_layout.change

This should end up firing precisely when we need to adjust our geometry,
rather than us guessing about it based on requests.

Additionally, variables xcursor and xcursor_mgr are only used
when xwayland is defined, so I make the variables declaration
contingent on whether xwayland is being used

No need to track our own order; wlroots has a reasonable default for us
already.

never ever ever tell anyone to sudo make

I am embarrassed to have let this slip through someone's merge.  Anybody

Define monitor's x,y at compile time

Replaces the outputOrder patch.
