This commit add an optional `--screen off` command to initialize Lua
without first adding the screens. This is inconvinient for most users
since it restrict the APIs that are usable out of the box.
However, this allows AwesomeWM to work independently from the hardware.
This means that when a screen is unplugged, it is the Lua code that will
remove the screen instead of CAPI pulling the carpet from under. It also
allows to ignore some screen areas before the screen is ever created.
Combined, it makes it possible to work with screens even when they are
physically disconnected. Finally, it will allow for an awful.rules like
API to control how screens are created.
All in all, some people need this for their setup and some people might
want to do it anyway for fine grained and/or dynamaic multi-screen
setups.
This commit also adds 4 new signals to `capi` to be able to
execute code at specific points during the initialization. The commit
improves naughty error notifications to work even if problems occurs
before the screens are added.
Note that AwesomeWM will exit if no screens are created. While it would
be easy to just call `refresh_screen();` after unsetting the magic
variable, doing so would have corner cases. Better be harsher and
prevent the user from shooting themselves in the foot from not reading
the f****** manual. Code introduced in future commits will take care
of automatically calling fake_screen in the event nothing is created.

This way their name doesn't get mangle by the broken magic. It will also
eventually allow to `error()` in the template when the implicit
`@function` is used.
This commit also fixes a large number of issues found while
proof-reading everything.
ldoc has a magical `@classmod` module type which tries to detect
what is a method and what is a static function. It fails about as
often as it works. This commit makes everything explicit to remove
such issues.

Ref #1373
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.

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).

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.

_NET_WM_STATE could contain _NET_WM_STATE_HIDDEN, which we interpret as
minimized. Minimized clients have WM_STATE set to WM_STATE_ICONIC, but
the code in client_manage() would later overwrite this to
WM_STATE_NORMAL.
Fix this by setting the initial WM_STATE_NORMAL by doing so before
processing _NET_WM_STATE.

The code here made sure that clients were not moved outside of the root
window. However, that's not enough, because clients can still end up
inside the root window, but outside of anything that is visible in some
output. Thus, just remove this.

Every call to client_ignore_enterleave_events() must be paired with a
following call to client_restore_enterleave_events(). In between these
two calls, no other calls to client_ignore_enterleave_events() is
allowed.
The code in banning_refresh() sometimes broke these rules. This can
happen because the code causes signals to be emitted and Lua code can do
basically anything.
Fix this by moving the calls into the called functions.

Before this commit, do this:
c.maximize_hoizontal = true
c.maximize = true
c.maximize = false
assert(c.maximize_hoizontal)
Would not work because the states were not preserved individually.
This commit fixes that. Awesome wont be confused about it's own
state anymore.
This may seem pointless, but when it come to undoing these
maximizations, it was ambiguous.
Before 4.0, maximizing could only be done in 2 operations.
4.0 add an unified way, but kept doing 2 operations. The old
Lua EWMH code to serialize the 2 operations was dropped when
the codepath was simplified and replaced by a generic version
in awful.placement. However this version never implemented
combining multiple mementos into 1.
This commit unify the maximize C code, drop the ugly macro
template and actually fixes a couple more issues that were
caused because request::geometry was sent twice.
I explicitly did not add client_shape_input property since querying the
input shape of the client window seems useless to me.

X11 does not allow to resize a window to size 0x0. Also, there are some
possibilities of integer overflows in our case. We tried to handle this
already, but there was a loop-hole: If the too-small-value is only
produced after applying size hints, then this was not caught.
Fix this by applying size hints before checking if the resulting size is
valid. However, this means some check needs to be duplicated to handle
the possibility of integer underflows while applying size hints.
