This patch fixes ticket #1168 to extend the window IPC event mechanism
to send IPC events for window focus and title changes. The newly added
window events use the same format as the already established "new"
event.
Specifically this patch:
* Moves the ipc_send_window_event() function from src/manage.c into
src/ipc.c and adds an argument for the change property of the event
* Updates src/manage.c to use the new function signature. To ensure
that the "new" event does not send the same event data as the
"focus" event, setting focus now happens after the "new" event
has been sent
* Adds IPC focus event notification to src/x.c. To workaround a problem
during window close when accessing the window name, a function has been
added to query whether a window is actually attached to its parent. To
avoid obsolete focus notification, a new field has been added to keep
track of the focus without any interference by the click handling
* Adds IPC title event notification to src/handlers.c. To avoid
obsolete title notification, a function has been added to determine
whether a window title has actually changed
* Updates the IPC documentation to include the new events
* Updates testcases/t/205-ipc-windows.t to include the "focus" event
in order to ensure the correct event sequence
* Adds two new unit tests, b/testcases/t/219-ipc-window-focus.t and
b/testcases/t/220-ipc-window-title.t to ensure proper "focus" and
"title" events
When the _MOTIF_WM_HINTS property of a window specifies it should have
no title bar, or no decorations at all, respond by setting the border
style of that container to BS_PIXEL or BS_NONE respectively.
This comes from the old Motif window manager. It was originally intended
to specify exactly what sort of decorations a window should have, and
exactly what sort of user input it should respond to. The EWMH spec
intended to replace Motif hints with _NET_WM_WINDOW_TYPE, but it is
still in use by popular widget toolkits such as GTK+ and Java AWT.
i3's implementation simply mirrors Gnome's Metacity. Official
documentation of this hint is nowhere to be found.

When i3 begins to manage a window, if the window opens on a workspace
that is not visible, the urgency hint on the newly managed window will
be set.
fixes#1088
If the currently focused window is in fullscreen mode, and a new window
is opened with WM_STATE_FULLSCREEN set, the new window now becomes the
new fullscreen window and gains focus.
During smart popup fullscreen handling, display all transient popups
that belong to the respective fullscreen application. A popup window
belongs to another window if the latter is reachable via the path
induced by the WM_TRANSIENT_FOR hints.
fixes#881
Added new event id (I3_IPC_EVENT_WINDOW) so that a an IPC client can
subscribe to events on windows. Added a basic window event that gets
triggered when a window gets successfully reparented. This new event
also dumps the container data, so that IPC clients can get the initial
window name. IPC clients wishing to see window events should subscribe
to 'window'.
With this commit, the default behavior is to display popups while there
is a fullscreen application only if the popup belongs to that
application (as determined by the WM_TRANSIENT_FOR hint which
applications have to set properly).
fixes#663
We need to verify that setting the event mask works, and we need to
include StructureNotify to get unmap events at any point in time.
Thanks darkraven for the pointer.
fixes#718
Previously, i3 would send width=0, height=0 to windows which were put on
workspaces created by an assignment (that is, invisible workspaces,
which do not get rendered normally).

The C compiler will handle (void) as "no arguments" and () as "variadic
function" (equivalent to (...)) which might lead to subtle errors, such
as the one which was fixed with commit 0ea64ae4.
Some of them are useless nowadays, others very unlikely to be a problem.
Those which might still be interesting somewhen in the future are just
commented out.
An example to set all XTerms floating:
for_window [class="XTerm"] mode floating
To make all urxvts use a 1-pixel border:
for_window [class="urxvt"] border 1pixel
A less useful, but rather funny example:
for_window [title="x200: ~/work"] mode floating
The commands are not completely arbitrary. The commands above were tested,
others may need some fixing. Internally, windows are compared against your
criteria (class, title, …) when they are initially managed and whenever one of
the relevant values change. Then, the specified command is run *once* (per
window). It gets prefixed with a criteria to make it match only the specific
window that triggered it. So, if you configure "mode floating", i3 runs
something like '[id="8393923"] mode floating'.
This involves:
• Compiling with xcb-util instead of xcb-{atom,aux} (they merged the libraries)
• Not using xcb-{event,property} anymore (code removed upstream)
• Not using the predefined WINDOW, CARDINEL, … atoms (removed upstream)
• Using the new xcb_icccm_* data types/functions instead of just xcb_*
(for example xcb_icccm_get_wm_hints instead of xcb_get_wm_hints)
Also I refactored the atoms to use x-macros.
This way, we can avoid to ignore UnmapNotify events generated by reparenting.
It is generally considerable to have as little ignored events as possible
due to side-effects.
Thanks to Merovius for doing a proof of concept on this one and
being a driving force behind the idea.
Using RandR instead of Xinerama means that we are now able to use
the full potential of the modern way of configuring screens. That
means, i3 now has an idea of the outputs your graphic driver
provides, which allowed us to get rid of the ugly way of detecting
changes in the screen configuration which we used before. Now, your
workspaces should not be confused when changing output modes anymore.
Also, instead of having ugly heuristics to assign your workspaces
to (the screen at position X or the second screen in the list of
screens) you will be able to just specify an output name.
As this change basically touches everything, you should be prepared
for bugs. Please test and report them!
