There is a client window C. Around this window, awesome adds a frame window F.
When the pointer is inside of C and then moves inside of F, we get a LeaveNotify
with detail=Inferior, but from our point of view, the pointer is still inside of
C, because F is contained in C.
Similarly, if the pointer is in F and moves to C, we get an EnterNotify with
detail=Inferior that we should ignore. However, for an EnterNotify the pointer
can now be inside of a titlebar, so this case has to be handled now.
The above explains the enter/leave behavior for clients. Let's now think about
titlebars: When the pointer moves from C to F, it cannot be in any titlebar any
more, so we must generate a leave event on that titlebar. Similar when the
pointer moves from F to C, but in this case we also have to figure out which
titlebar now contains the pointer.
This patch makes the code handle these events with detail=Inferior correctly.

This adds a global variable that tracks the drawable that is currently under the
mouse cursor. This new variable is then used so that we get consistent behavior
for enter/leave signals. Such signals are now also generated when a MotionNotify
event tells us that the pointer is now in a different titlebar.
Before this, it was possible that we did not generate a leave event on a
titlebar since the LeaveNotify contains the cursor position after the leave and
we did not manage to figure out which titlebar was left.

When you run a mousegrabber, the C code calls this callback when the pointer is
moved or when a button is pressed/released. However, the button state is totally
bogus on press/release events, always claiming that the button that was
pressed/released is the only button that is pressed (even for release events!).
This commit fixes up the code so that the button state after the press/release
event is passed to the mousegrabber callback function.
Fixes: #280

This patch provides functions to get/set current keyboard layout.
Current implementation doesn't support any configuration of layout,
it's a merely a layout indicator and switcher, however layout
configuration can be set by tools like setxkbmap or by any third-party
tools.
Everything that needs the lua_State should create a local variable like this:
lua_State *L = globalconf_get_lua_State();
This ensures that the compiler warns if there are two variables with name "L" in
scope. The idea here is that it should become harder to accidentally use the
global lua state instead of the state of the current state.
While writing this commit, I found another place that gets its wrong: Reading
client.focus from a coroutine was broken, since it was returning the result on
the main thread instead of the current one.

I never saw a single program that set a border on its own windows. However,
awesome commonly sets borders on its clients and the position of a client is the
part outside of the border. So when processing a position request from a client,
we also have to include this border and fix things up correspondingly.
However, the same isn't needed for the client size, because the size does not
include the borders, but just the titlebar plus the "real" client content.
Thanks to Daniel Hahler for providing a simple test case based on urxvt for
debugging this!

Whenever a titlebar of a client needed to be refreshed, all (possibly) four
titlebars would get completely refreshed. So if someone actually added more than
one titlebar to a client, awesome would copy each titlebar's content to the
window four times. Fix this by introducing more fine-grined functions for
uploads.
This also makes awesome only update the affected area when it gets an expose
event for a titlebar instead of all four titlebars completely.

A drawin's and a client's bounding and clip shape can now be queried and is

c.shape_client_clip. All of these properties now emit signals when changed.

The idea was to track the current list of pressed and depressed mouse buttons,

corresponding release event. This is quite bad.

To avoid some oddities, awesome sets the input focus lazily. Instead of
immediately sending everything to the X11 server, awesome just sets a flag "have
to update the focus later".
However, this can cause problems. As Stefan noticed, awesome can forget about
focus changes on FocusIn events when such an event comes in while we still have
a pending focus change.
The fix here is to send out the pending focus change before we record the fact
that another client now acquired the input focus.

This commit makes it possible to add titlebars to a client. These titlebars are
drawables.
The drawin's input handling is moved to the drawable. This allows it to use the
same code for drawin and titlebar input handling, although there are lots of
differences between the two on the C side.
On the lua side, a new wibox.drawable module is created which handles all the
drawable-specific magic and which can also be used for titlebars.

When a keyboard grab activate/deactives, the input focus jumps to the window
which does the grab. These FocusIn events sometimes managed to confuse awesome.
The symptom was that a newly mapped/started client didn't receive the input
focus:
- You press your key-combo to start a terminal. This activates a passive grab
and the input focus jumps to the root window
- The terminal opens and the "manage" rule does client.focus = c
- This doesn't set the focus yet, but instead causes
globalconf.focus.need_update = true and .client = new_terminal
- Before the focus is updated, the key combo is released and the focus jumps
back to the previously focused client
- The FocusIn with mode == Ungrab causes awesome to think that the previously
focused client got focused again and thus globalconf.client.focus gets re-set
to what it was before
- Finally the focus is refreshed and the previously focused client gets focused
The fix is simple: We don't need the FocusIn events which are generated when a
grab activates or deactivates, so we can just ignore them.
Thanks to Majic for reporting this to me.

This reverts commit 0682499895.
We have to handle all the UnmapNotifies due to ICCCM. The bug this was trying to
fix is now fixed by 9ab8cd4039 ("Set our event
mask on the root window later") instead.
We got XCB_EVENT_MASK_SUBSTRUCTURE_NOTIFY on the root window, but we also have
XCB_EVENT_MASK_STRUCTURE_NOTIFY on the individual client windows. Since we are
reparenting our windows, we can safely ignore all UnmapNotifies that we get
through the root window.
This fixes a bug if there were any windows already present before awesome
started. Those were obviously already mapped which means that ReparentWindow
would cause an UnmapNotify for them on the root window. This commit makes us
ignore that UnmapNotify and thus not throwing away the window immediately again.

According to the Inter-Client Communication Conventions Manual, if you want to
switch your window to withdrawn state, you unmap it and send a synthetic
UnmapNotify to the root window.
This synthetic event fixes a race condition. When you map and unmap a window
quickly, the map will generate a MapRequest for the WM but won't actually map
the window. Thus, the unmap will be discarded (-> window not yet mapped) and the
window stays map once the WM handles the MapRequest
Before this patch, awesome just ignored the synthetic unmap notify which caused
the bug to appear again. With this patch it doesn't happen anymore.
