alloca() allocates stack space. The image that we were producing is possibly
huge which means that we were asking for e.g. 9MiB of stack space. This is not
really a good idea and caused crashes.
Fix this by using heap memory instead.

This reverts commit 27f9c0177a.
This commit broke code like the following because reading client.focus would
still return the previously focused client:
awful.client.focus.byidx(1)
if client.focus then client.focus:raise() end
This moves the appropriate fields for client focus from screen_t to globalconf
since only the first screen's fields were used anyway.

This makes awesome support only a single X11 protocol screen. If you are still
using zaphod mode, you can run multiple instances of awesome on the single
screens, e.g.:
DISPLAY=:1.0 awesome & DISPLAY=:1.1 awesome &

Previously, if a client had nofocus == true, it wasn't unminimized if sth tried
to focus it. Also, if this client had the WM_TAKE_FOCUS protocol, the focusing
would fail since it's an error to set the input focus to an unviewable window.
For consistency, this also moves the code that sets a client's minimized
property to false into client_unban() since it doesn't make sense to have a
minimized client unbanned (i.e. visible).

If this property is true, setting "client.focus" to this client might have some
effect. If it is false, setting "client.focus" will be ignored completely.

Previous, there was a round-trip after each request for a property since we
waited for the reply immediately. Instead, it makes a lot more sense to first
send all of the requests and then handle all the replies. This now takes only a
single round-trip for all the properties from client_update_properties().

Instead of calling each property handler with a property reply, it's now up to
the handlers to request the properties.
Signed-off-by: Uli Schlachter <psychon@znc.in>
For each property we handle, there is now a function which sends a request and
returns the cookie and a second function that takes the cookie and saves the
result in the client_t struct. This should make it possible to improve our
latency later on.

This should fix an actual race condition:
- Client unmaps its window (UnmapNotify for awesome)
- Client maps its window (MapRequest for awesome)
- Due to the UnmapNotify: client_unmanage() runs and reparents the window back
to the root (ReparentNotify)
- Due to the MapRequest: client_manage() runs
- Due to the ReparentNotify: We call client_unmanage() again and now the
client's window is lost.

According to ICCCM, if a client wants to reuse one of its windows, it has to
wait until the WM updated WM_STATE. This means updating WM_STATE should be the
very last thing we do when unmanaging a window.

When a window is moved, it should be sent a synthetic ConfigureNotify describing
its new position. This also documents why we send a synthetic event if nothing
was changed in response to a ConfigureRequest.

If a client sets its own border on its window, the results look broken. This was

Fix this again by stacking the frame window correctly.

When a client is unmanaged, we destroy our frame window. But since the client's
own window was still a child of the frame window, it was destroyed, too. This
commit fixes this by reparenting the client's window back to the root window
first.

This splits up client_getbywin() into two different functions. One of them finds
a client by its frame window, the other checks against the client's own window.

Each window is now reparented under a window created by awesome. This window is
NOT visible, this commit should not cause any visible differences. Instead, this
is done to work around problems with X11.
The only alternative would be to ban windows by moving them offscreen which is
ugly in itself and breaks pagers. Doing it like this seems to be the better
solution.

libxcb-property will be dropped from xcb-utils in the next release, because
upstream thinks it's not really useful and well-designed.

While a window is in the save set, it will automatically be made visible again
when awesome exits/dies. This makes sure that the next window manager will pick
this window up and handle it properly again.
But when a window explicitly asks not to be visible, it doesn't want to be
visible. Even if awesome dies. So we should remove the client's window from the
save set in client_unmanage.

The window is now no longer enlarged to make it fit into its aspect ratio, but
only ever made lower. This was verified with a small test app that sets a min
aspect ratio of 0.5 and max aspect ratio of 2.
Signed-off-by: Uli Schlachter <psychon@znc.in>
ICCCM says that the min size should be used for the base size if no base size is
specified. The only exception is when calculating the aspect ratio of the
window, in that case only the "real" base size may be used.
Awesome didn't do this last part before.

If a window is fullscreen it is supposed to cover the full screen. Obeying size
hints makes no sense in this case.

A new window is by default above all other windows. This means that when we map
it and then *later* move it to the correct place in the stacking order (thanks
to lazy restacking), the window on the top of the stack has to redraw itself.
I noticed this via naughty notifies redrawing themselves after opening a browser
window.

When an application loses its connection to the X11 server, all the windows in
its save-set are saved by reparenting them back to their closest ancestor. Also,
to they are unconditionally mapped. This second property is exactly what we
need: All windows should be in mapped state, else the next window manager which
starts up won't be managing them.
This should fix all bugs where clients where lost due to a restart, yay! :)

When one sets a client to fullscreen, this is what currently happens:
- lua code: c.fullscreen = true
- The C code emits request::fullscreen without having touched the client's
fullscreen property yet (c.fullscreen is still false)
- awful.ewmh changes the client's geometry to fullscreen via c:geometry()
- This causes property::geometry to be emitted
- awful.layout reacts on this and causes the screen to be re-arranged, undoing
the fullscreen geometry set in awful.ewmh
- The C code for c.fullscreen = true continues and actually changes the client's
fullscreen flag
The result of this is that we get a client which thinks it is fullscreen'd
without actually being that.
Fix this by first changing the client's fullscreen property and then emitting
request::fullscreen. Same thing for maximized_{vertical,horizontal}.
Thanks to Jim Pryor for reporting this bug and helping reproducing it.
