It used to be unmap when we receive its MapNotify, but now since we discard
events received before we grab X server, that event it lost. But it
turns out we can just unmap it when it's first created, no need to wait
for the MapNotify.
Partially fix#160

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.

After converting from struct conv to xorg format, cache the result to
save CPU time.
And remove an unused function.

Instead of storing them as an array of xfixed.
Might cause some performance overhead for the new backend, because
it is allocating a buffer to do the conversion every frame. Will fix
later.

Background: To bind a Xorg window content to a OpenGL FBConfig, which
has to match the color format the Xorg window is using.
Previously, compton just find a FBConfig that has the same depth. This
led to chjj/compton#477, which has been fixed by a ugly hack.
The commit refactor the lookup mechanism to take as much into
consideration as we reasonably can. Hopefully preventing similar
breakages in the future.
Also, some code sharing between the old and new glx backend.

Slightly clean up header inclusion with the help of clang's module system.
It's better for files to include the things you need directly.

They should be useful for the refactored backends.
Renamed x_create_picture to x_create_picture_with_pictfmt.

Moved:
* Blur kernel related functions to kernel.c
* Vsync related functions to vsync.c
* paint related functions to render.c
This will make the `split-backend` branch easier to rebase.

This should give us sane item size, i.e. the item has the same number of
bits their format says they have.

IANAL, but I think I am allowed to add missing copyright notices for
someone else. And I did my best job using git history to figure out who
wrote which functions. So I hope everything is fine.
Instead use win_has_alpha to check for alpha channel, window mode is
reserved for determine if the window is possibly transparent.

Also move static function prototypes out of compton.h. Seems like the
previous developers didn't know what header files are for.
Seems to have bugs after the split.
