core: mark newly created window as damaged
Damage could have already happened at the time we call fill_win on a new
window. It's too difficult, or impossible, for us the find out if that
happened. So just blindly mark window as damaged.

core: wait for the result xcb_grab_server before doing anything
Make sure X grab server is finished before calling x_discard_events in
session_init. Otherwise x_discard_events won't be able to discard all of
the events that were sent before we grab the server.

Map newly created window in handle_new_window
A window might be mapped before we had the chance to start managing it.
So check to see if we should map a window after we call fill_win on it.

Delay window managing
Create a "critical section" in draw_callback by grabbing the X server.
Delay the managing of newly created windows until we enter the cricial section.

win: handle destruction of unmanaged window
Previous destructions of unmanaged window are silently ignored, causing

x: add x_discard_events
Also, during session_init, discard old events after we grab the server.
If we don't do that, old, out dated CreateNotify will cause us to add
the window with the same id multiple times. Here is an explanation of
how that could happen:

1. compton connects to X
2. a new window created by someone else, X send us a CreateNotify
3. compton is initializing, so it didn't handle the event.
4. compton pulls a list of all windows from X. This will include that
   window created in (2)
5. compton starts to handle event. it will handle the CreateNotify sent
   in (2), thus adds the same window twice.

win: fix add_win_top
Instead of reusing add_win_above with the id of the window on the top
of the stack, we create a new function that takes a list_node.

Fix a problem when the window on the top of the stack is destroyed. Because
add_win_above search for windows from the hash table, it won't find that window
and returns NULL.

win: split struct win
Currently compton handles window creation event by immediately query all
the information it needs and create a window struct with that
information. However, this is prone to race conditions.

In the future, we want to react to window creation event by creating a
placeholder in the window stack, and only query window information in a
critical section where the X server is grabbed by us.

This commit split struct win into two struct, one as placeholder, the
other for holding actual window information.

new backend: fix crash when window's shadow state change
Create a shadow image for a mapped window when it's shadow become enabled.
For unmapped window, the shadow image is created during mapping. Also,
if the window has IMAGE_ERROR flag, it won't be render anyway. So shadow
image won't be created in that case either.

core: fix a case where closed window is left on screen
If a window is unmapped, then mapped to a different position on screen
before fade out is completed (when fading is not enabled, it has to be
mapped again in the same frame), the old window content is left on screen.

This is because when this happens, we didn't add the unmapping window to
damage.
