inline handlemove/handleresize

render_data only needs coordinates, not Client

abc

give types some more dwm-like typedef names

use expressions in sizeof instead of type names

no longer need resize_edges (always bottom right)

Also gets rid of the clunky move+resize code

ditch the moverequest/resizerequest xdg stuff

dear window, you are not the window manager

No need for struct dwl_server

the only use was to hold global state, which is now actually global

make server a global

dwm isn't afraid of global variables

dwm-style enum

alphabetize functions

functions: dwm style and more dwm-like names

add spawn and termcmd

treat startup command as long-running

Not quite a perfect mirror of xinit, where the startup command execs the
window manager, and the termination of that process brings down the
windowing system, but it might be the Wayland analogue.

fix typo in comment

implement Button: movemouse, resizemouse

add CLEANMASK like dwm

make key mappings configurable in config.h

start factoring Key actions into functions

Start with tinywl

Add a config.h into which configurables can be moved.
