Cursor images are fairly small and having one pool for each image adds
a lot of unnecessary overhead. Instead, create one large pool and
allocated all cursor images from that.
In order to do that, however, the code that creates shm surface needed
some refactoring. This patch adds a new struct shm_pool that is used
by the cursor and also changes struct window to use it.
These new protocol events allow us to tell which outputs a surface is on, and
potentially update where we allocate our buffers from.

The biggest performance bottleneck while resizing is the continous
setting up and tearing down of mmaps and faulting in pages. This commit
introduces a per-window pool that we'll allocate buffers out of if it's
available. Then we set initialize it to a big shm pool when we start
resizing and free it when resizing is done.
There was a lot of code here to do a lot of work we didn't need to do.
If we damage a surface with a shm buffer attached, all we need to do
is to re-upload the damaged region to the texture. As for drm buffers,
we don't assume anything changes on attach and only update the
regions the client tells us to update in the damage request.
On one hand, getopt (in particular the -o suboption syntax) sucks on the
server side, and on the client side we would like to avoid the glib
dependency. We can roll out own option parser and solve both problems
and save a few lines of code total.
We just set the input region to the bounding box of the window frame
and set the opaque region to be the opaque rectangle inside the window
if the child widget is opaque.
The X11 compositor currently posts its key presses as keycode - 8; this
is due to X11 having a historical minimum keycode of 8, whereas evdev is
numbered starting from 1. So while the KEY_* constants begin with
KEY_ESC at 1, the corresponding keycode in both X11 and the XKB keymaps
is 9.
window, on the other hand, was relying on xkb->min_key_code being 8 to
translate its keycodes back to useful values in the XKB 'evdev' keycode
map. min_key_code may not always be 8, for restricted subsets of the
keycode map.
Perhaps not the best solution, but at least consistent.

This change depens on the Wayland core commit:
"protocol: remove absolute coordinates from pointer".
Remove the absolute coordinates from pointer motion and pointer_focus
events.
