A client c could have no c.machine or no c.pid because the corresponding
properties are not set on its window. Previously, the C code would return an
empty string or 0 for these values. This commit makes the C code give Lua no
value instead (not even a nil).

Instead of computing the workarea whenever some Lua code asks for it, it is now
remembered explicitly as a property on a screen. This allows us to only emit
property::workarea if the workarea actually changed.

Apparently the spec allows to set the _NET_STARTUP_ID value on the property that
WM_CLIENT_LEADER points to instead of the window itself. Thus, if we don't find
a _NET_STARTUP_ID on the window itself, check again on the client leader window.
Apparently GTK even does this (for whatever reason...)...

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 }.

Instead of focusing the root window, we now create a "focus window" inside of
our frame window. This window is placed so that it is not visible, but we can
grab key bindings on it to simulate the window having the input focus.

Even when a screen is just an integer, the code becomes a bit more
self-documenting. Even better, if we start to handle screen objects to Lua
instead of screen indicies, there will only be one place that needs to be
changed.

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".

ICCCM specifies when the WM has to send a ConfigureNotify. Java does not care
and wants one all the time. Meh.

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.

When a client is unmanaged, we know emit mouse::leave on its titlebar before the
client object is invalidated, so that Lua can still work with it. Before, this
event was emitted only when we got a LeaveNotify from the X11 server.

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?

The bit that indicates that the base size is set is
XCB_ICCCM_SIZE_HINT_BASE_SIZE. However, instead this code checked
XCB_ICCCM_SIZE_HINT_P_SIZE which is set to indicate how the initial window
position is chosen. So we were checking the complete wrong bit. Whoops...

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
focus.

This makes it possible to add something similar to a __index / __newindex
metamethod to all our C objects. Based on this, Lua can then easily implement
arbitrary properties on our capi objects.
From http://standards.freedesktop.org/wm-spec/latest/ar01s05.html:

awesome prefers fullscreen internally already. With this patch, the
previous maximized state will be restored after leaving fullscreen mode.
