A client cannot be used any more after it was unmanaged. Similarly, Lua
shouldn't be allowed to e.g. assign a client to a screen that was removed. This
commit adds such a checker which "breaks" all screens which are not in the
global screen list.

This commit adds a "removed" signal to screens. Together with the "added" signal
that we have since a while, this allows the C code to update the list of
available screens dynamically without needing to restart.
So far, this code received only minimal testing. So far, I don't have a nice
idea on how to easily test this...

We once had the problem that with the nvidia blob, the X11 server told us that
"yes, I do support RandR; there is just a single big screen" even though there
were multiple screens and they could be queried for via Xinerama. To work around
this, we started to ignore RandR if it only provided information about a single
screen.
Our long-term goal is to stop restarting on RandR screen changes. Thus, even if
only a single screen is defined during startup, we should still use RandR later
when another screen is added. This means that we cannot just ignore RandR if it
only mentions a single screen.
This commit copies what GTK+ does: If there is an output named "default", then
some compatibility layer is assumed and we ignore RandR.
I have no way to test if this really does the right thing.

Instead of adding all screens directly to globalconf.screens, the individual
"scanner functions" now get a screen_array_t as their argument and add the
screens there. Also, they no longer emit the "added" signal themselves (through
screen_add()), but the caller does now does this instead once all screens are
found.
This commit drops the "deduplication" of screens. This likely means that clone
mode causes duplicate screens. This will have to be re-added later.

Remove request::fullscreen and request::maximized_* and use
a single request for them. The other client resizing features
will soon also start to use this.
In the case where one want to put the cursor at the middle of the
workarea, it is logic to do:
x=screen.workarea.x+screen.workasrea.width/2
However, this can cause floating points. This commit move the
burden back to the C-API so the Lua placement code doesn't have
to add a large number of rounding methods. Given 1 type of rounding
cover a vast majority of use cases for each types of coordinates,
the C-API can take care of it in peace. For the other corner cases,
it is still possible for the Lua code to do the rounding there, but
no longer necessary. The convenstions are:
'x' and 'y': use round (move to the closest point)
'width' and 'height': use ceil (to avoid involontary truncating)
This change catches things like c:geometry { width = -42 }.

XRandR 1.5 adds support for the new monitor objects.
'Monitor' is a rectangular subset of the screen which represents a
coherent collection of pixels presented to the user. Each Monitor is be
associated with a list of outputs (which may be empty).
The patch below matches 1:1 screens in AwesomeWM with XRandR's Monitors.
This way I get one screen across my 4K monitor, which is represented by
two CRTCs.

Instead of focusing the root window, we now create a "focus window" inside of

When we manage the transient before the main window, the client object's
.transient_for property would stay nil. This happens because the property points
to a window which we don't know (yet) and thus is ignored.
Fix this by remembering the value of WM_TRANSIENT_FOR and checking in
client_manage() if the new client is the "missing window we did not find
before".

To quote from ICCCM (§4.1.2): "The window manager will not change properties
written by the client."
We tried to do this anyway to update WM_HINTS so that the current urgency state
is reflected. Apparently, Chrome does a similar read-modify-set cycle and the
resulting race condition meant that the "accepts input" hint on Chromium's
window was permanently disabled.
This helps with https://github.com/awesomeWM/awesome/issues/670, but I still
think that Chrome shouldn't try to implement "please don't focus me when I do
the following" by temporarily claiming "please don't ever focus me".

This allow layout "arrange" to be called less often and react on
the cause of the change itself rather than it's consequences
(usually, the "focus" signal).
Previously, the layout were re-arranged everytime the focus changed.
Now, with "raised" and "lowered", it require less "arrange".
"swapped" allow smarted layouts. Currently, swapped cause a full
re-arrange. It re-read the "index" list from scratch and create
a "new" layout. With "swapped", incremental layout changes are
possible.

Some words about X11 event handling: Every X11 client can select input on any
window. For this, inside the X11 server each window has for each client a
bitmask for the kind of events that this client is interested in. When a mouse
button is pressed inside of a window, a corresponding event is generated for
that window and sent to all X11 clients which asked for
XCB_EVENT_MASK_BUTTON_PRESS. When no client is interested in this event, the
event is propagated to the parent window and the same procedure is done again
here. This continues up until the root window is reached.
Some words about the event masks that awesome uses: For clients, we ask for
button press events on the frame window that we reparent the client window into
so that we get any kind of press on the titlebar (and also events inside of the
client window if the client itself doesn't care for click events?). We are also
interested in button presses / releases on the root window. However, before this
commit, we didn't actually ask for button events on drawins (e.g. the wibox).
This worked fine, because no one asked for these events and the event propagated
to the root window where it was then sent to awesome.
However, newer Qt versions do something weird and the above broke. I don't
actually know what is going on. I know about the above propagation rules, but
looking at protocol traces of what Qt does, awesome should still get the button
events. During startup, Qt asks for button events on its own windows. After a
hotplug event, it asks the same again, but now also includes the root window.
So... how can Qt asking for button events on the root window cause awesome not
to get them? I have no idea.
(And yes, I guess that Qt asking for mouse events on the root window is a bug,
but I have no idea how exactly this happens nor about any other side effects of
it).
This commit makes us ask for button events on our drawins so that the server
will send them to us. This is the right thing to do anyway and it was reported
to have some positive effects.

The only exception is the window for _NET_SUPPORTING_WM_CHECK. That window

Right after startup with the default config we now have the following situation:
$ xwininfo -root -tree

Before this, we grabbed the keys on the frame window. That meant we only got key
events for things that nothing else grabbed directly on the key window.
After this, we grab directly on the client window itself and so we "fight" with
everything else which wants to grab keys. I don't actually know how the winner
is decided... First come, first serve, the rest gets an error?

Whenever client.focus == nil, we set the input focus to the root window to
express "nothing has the input focus". However, thanks to the way X11 input
works, this means that whatever is under the mouse cursor gets keyboard input
events. This can easily be reproduced with urxvt and some small addition to the
config to unfocus things.
This commit changes things. Instead of focusing the root window, we create a
special "no focus" window that gets focused if we want nothing to have the

When minimizing a client, we temporarily ignore events for the client window (so
that we don't get the UnmapNotify event that we are causing for the unmap) and
for the root window (I don't actually know why, no "harmful" events should be
caused...).
However, we weren't ignoring events on the frame window itself. This commit
fixes that oversight.
The problem here is that the pointer could be inside the window that is being
minimized. When we then unmap said window, the pointer will now be inside of the
frame window and the X11 server will thus generate an EnterNotify. When we
handle this event later on, we emit mouse::enter on the client and e.g. the
default config then focuses this client, which undoes the minimization.
This fixes a regression introduced in commit 3aeac3870c and fixes#92.
