Between xcb_grab_server() and xcb_ungrab_server(), XCB's output buffer
might fill up. Thus, the GrabServer request might already have been sent
to the server, but the following UngrabServer request could end up in
XCB's output buffer. There, it might sit around for quite a while and
cause problems.
Since we cannot detect when XCB's output buffer fills up, we just always
flush after generating an UngrabServer request.

Instead of refreshing screens at the end of the current main loop
iteration, this now uses a GLib idle source with a very low priority.
This increases the chance of batching multiple refreshes together. Also,
this means that awesome_refresh() does less work.

As requested in the review, instead of just having a single string
argument, selection_acquire() now has a table as its argument. It
searches the string under the "selection" key here.

Today I learnt that _NET_WM_STATE_STICKY means something else than I
previously thought.
ICCCM and EWMH support virtual desktops that are larger than the actual
screen. The idea is that one can scroll through this virtual desktop,
which means that e.g. all windows move to the left, so one can see the
windows that are further to the right.
_NET_WM_STATE_STICKY indicates that a window is sticky. This means that
it does not scroll with the virtual desktop, but instead sticks to its
current position.
In AwesomeWM, we use a different definition. A sticky window is always
visible, even when it is not tagged with any of the currently selected
tags. This behaviour is indicated in EWMH with a special value of
_NET_WM_DESKTOP. This commit updates the code to actually set this
special value.
This fixes attaching tabs in Google Chrome when the "target window" is
sticky (in the AwesomeWM sense).

When a selection transfer is done, we are no longer interested in events
from the selection window. However, this happens after we set the
property to indicate end of transfer, not before.
The (untested) theory here is that this should make selection transfers
from AwesomeWM to AwesomeWM, i.e. internal transfers, work.

This now creates a selection transfer object and requests Lua to reply

This allows to voluntarily give up ownership of a selection. Because
selection acquire objects cannot be garbage-collected before they are
released, this also gets rid of the function destroying the window when
its selection acquire object is destroyed. Instead, the window is
immediately destroyed when no longer needed.

When the selection that is watched by an active selection watcher
changes, then the signal "selection_changed" is emitted on the watcher.
This signal has one boolean argument that indicates if the selection is
owned. This means that this argument is false when the selection owner
went away and the selection now has no owner at all.

These objects are created via e.g. selection_watcher("CLIPBOARD") to
track the CLIPBOARD selection. They start watching when their .active
property is set to true and stop when this property is unset again.
This commit implements the Lua side of that: A list of active watchers
is kept and updated when needed.
The next commit will add the X11-side of this so that these objects
actually do something.

Until now there wasn't much documentation available about how to use
these properties. With the new work on `awful.spawn` that rely more and
more on `awful.rules` integration, it is worth fixing.
This commit add a new documentation section and a future commit will
aggregate them to generate an index.
Previously, this function overwrote the value of its argument with the
result. After this change, the function merely changes the given
variable by the calculated argument.
Thus, the old behaviour is achieved by setting the variable to zero
before the call, which all callers already did. However, for most
callers this change means that a temporary variable can be removed and
instead xwindow_translate_for_gravity() will directly change the target
variable.
No change in behaviour intended.

There are two ways in which the input focus can change: Lua can request
a change and the X11 server can inform us that the input focus changed
(because some application changed it).
In the first case, we still have to inform the X11 server about the
desired change, in the second case we must not to avoid races due to
X11's asynchronous nature.
However, there was a case where we screwed up: When a focus change is
still pending, meaning that Lua assigned the focus elsewhere, but we
have not yet sent this focus change to the X11 server, we could get an
event from the X11 server telling us that the focus changed. To make
sure that the pending focus change is not lost, we sent the focus change
out in this case (call to client_focus_refresh() in
event_handle_focusin()). After sending out this pending call, we updated
the internal state to record that whatever the X11 server just told us
had the focus. The intention was that our just sent-out focus change
will cause the X11 server to send a new event and our to-be-focused
client then has the focus.
However, if the pending focus change was for a client which only showed
up in this event loop iteration, the client was still banned. This means
that client_focus_refresh() would call client_unban() to be able to give
the focus to this client. However, since awesome (partly) allows to
"focus" currently banned clients, client_unban() recorded that there is
a pending focus change. This caused confusion later on.
In this specific bug, a main window opened a dialog, and when this
dialog was closed, a new dialog window was opened immediately. When the
first dialog was closed, Lua (the focus history) gave the input focus to
the main window. Now, a new dialog showed up and Lua focused it. Next,
we received the event from the X11 server telling us that the main
window was focused. Because there was still a pending focus change to
the new dialog window, event_handle_focusin() called
client_focus_refresh() to send out this focus change. This set
globalconf.focus.need_update to false and continued. However, because
the new dialog only just now appeared, it was still banned, meaning that
client_focus_refresh() had to call client_unban(). This set
globalconf.focus.need_update to true. Thus, when client_focus_refresh()
returned, globalconf.focus.need_update was incorrectly true. Next,
event_handle_focusin() recorded that the main window had the focus.
Thus, it now appeared as if there was a pending focus change for the
main window. Next, we got the event from the X11 server telling us that
the dialog is now focused, and because focus.need_update was set,
awesome now send out a focus change request for the main window.
Fix this race by unsetting globalconf.focus.need_update at the end of
client_focus_refresh() and not at the beginning, thus making sure that
client_unban() cannot set this flag again.

When a window has a WM_TRANSIENT_FOR property that is later unset,
awesome would still keep c.transient_for pointing to the previous
"parent client". This commit fixes that.
First, property_update_wm_transient_for() is fixed so that it unsets
c->transient_for_window if the WM_TRANSIENT_FOR property is deleted.
Additionally, this then calls client_find_transient_for() to update the
c->transient_for pointer.
Secondly (and a bit unrelated), this changes client_find_transient_for()
so that it always sets c->transient_for. Previously, if updating this
property would introduce a cycle in the transient_for relation, it would
just leave c->transient_for with its old value. After this change, it
gets explicitly set to NULL instead.

When a new client appears, we reparent its window into a window of our
choice so that we can add decorations. However, windows can be difficult
making the reparenting fail. For example, some snapshots of GTK+ set a
parent-relative background, which means that its parent windows have to
have the same depth as the window itself. This makes reparenting fail if
transparency is used/supported.
Make the failure mode... different, by checking if reparenting
succeeded. If it failed, we print an error message and unmanage the
window immediately. This means that those GTK+ windows just do not
appear at all, instead of behaving weirdly.
This idea of this patch came from i3.

The systray_cleanup() function gives up the _NET_SYSTEM_TRAY_Sn
selection ownership and should be called only when Awesome exits.
Calling systray_cleanup() from drawin_systray_kickout() is not correct,
because drawin_systray_kickout() is called when the system tray window
needs to be hidden, including the case when the last tray icon was
removed and the tray became empty.
