I was creating 2000 wiboxes in a loop (don't ask) and creating them took
forever. According to callgrind, there were about 2 million calls to
xcb_configure_window() and most (if not all) of them were from client_stack().
Awesome spent 70% of its cpu time in these client_stack() calls.
client_stack() is O(N^2) on the number of clients (it walks the list of clients
itself twice and each call to client_stack_above() walks the list too) and O(N)
on the number of wiboxes (it walks the wibox list twice). So obviously calls to
it should be rare.
This patch makes client_stack() only set a flag which is later checked. This
should reduce the number of restacks to the bare minimum. With this patch,
neither xcb_configure_window() nor anything else client_stack() related shows
up as having a lot of calls or using much cpu time.

Pretty much every single source file needs this struct, so it makes sense to
define it in a common header instead of in every single .c file.

- WINDOW_TYPE_DOCK are chosen first.
- Top/Bottom take precedence over Left/Right.
- Struts are automatically updated.
- Automatically avoid overlap with other struts or wibox'es.

Version 1 was supposed to store somehow the mouse coordinates to drop
spurious EnterNotify.
Now, we use a simpler way: we just tell the X server we do not want to
receive this events while we are arranging, since we would get spurious
ones.

- In many places i see people correcting for border width and titlebars.
- This new definition is the equivilant of what used to be fullgeometry.
- The internal geometry is now contained to a few functions that few people ever touch.
- This should avoid confusion and make code easier.
- Also protect against several unsigned overflows.

- From now on clients shall remain mapped for their entire lifetime.
- This should seriously boost tag switching speed with composite active.
- A lesser improvement may be noticed in non-composite situations.
- Titlebars that are set to invisble are still unmapped.
Since it would clutter the implementation and titlebars are cheap to render.
Not to mention that invisible titlebars are pretty rare.
- It's safe to attach titlebars while the client is banned.
- Titlebars are explicitly removed at exit.
