Sometimes we unref the icon image, but we did not reset NULL, which
can make the client refering to a not-refed image.

This patch fixes focus hooks calls - for every call to focus hook, there
should be call to unfocus hook.
Focus related info:
In this shape, awesome doesn't support multiple focused clients, that
means it follows the rule "there is only a single focus", which is not
true for MPX. To change this, I think it will need some magic with
FocusOut events handling and changes to some structures
(e.g. globalconf.screen_focus, screen_t.client_focus should be arrays) :p
Now we don't need to handle FocusOut events.

That is necessary because key_find() assume we always get one and only
one keybinding for an event, which is wrong, since we can have several.

Lua can preallocate space in table for array or non-array elements type.
This should improve performance when setting table, so when we can we
use lua_createtable() since this is just a gain.

We should prevent focus stealing, in case when there are e.g. 2 clients
on separate tags, first client has focus, and we receive FocusIn event
for second (invisible) client.
This patch adds prevention in the focus update handler. It sets focus
on previously focused client, when FocusIn event destination is
invisible(untagged) client.
This should fix FS#497.

We now use a client_array_t which is more efficient and we reverse the
array order compared to before.

This code actually belongs to 'root' since it does not send events to a
client but simply to X.
The window argument is only used in motion event, so fix that also.

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.

The name LAYER_OUTOFSPACE suggests that this is a real layer on which windows
can be put, but it's only used as an integer which describes the maximum
allowed / used layer.
Therefor, renaming it to LAYER_COUNT and adding a comment which describes this
might make sense.

- We are tracking focus, using FocusIn/FocusOut events handlers, so user
should never be confused about which client has focus
- window_setfocus function generates focus change requests to the X server
- client_focus uses window_setfocus to set input focus
- revert_to when setting input focus set to Parent, compliant with
ICCCM convention ([1])
- DEBUG flag for those who want to debug focus handlers
Most of the changes, are compliant with X11 handbook ([0]), but some
where obtained experimentally.
Kudos to Maarten Maathuis who helped a lot with this.
