At the beginning of every main loop iteration, we check for new events
from the X11 server. However, it's theoretically possible that during a
main loop iteration new events arrive and are read by libxcb into its
internal buffer. This would mean that the fd connected to the X11 server
is not readable and thus we do not wake up to handle these events.
Handle this by checking for pending events before calling poll(). If a
new events appears, we set the timeout for poll() to zero and will then
handle the new event in the following iteration of the main loop.

Otherwise there is a small, unimportant memory leak. More important is the fact

This code removes code which could only be hit be running awesome --search '' or
awesome -c ''. In both cases there are many possibilities for weird/invalid
arguments and I don't see why the empty string deserves special treatment.
Note that awesome --search does NOT hit this code, because getopt_long handles
the case of "completely missing" arguments itself.

When you run "awesome --foobar", a warning will be printed (by getopt_long())
and awesome just ignores the invalid argument. That's unusual and weird.
This commit produces an error instead.

The same effect could be achieved by modifying $LUA_PATH or with symlinks, but
having a special option to do this seems easier.
Note that the man page translations were generated via Google translate. I'm
looking forward to people submitting correct translations...

This function needs the event numbers for events from some extensions. These are
assigned dynamically by the server. Right now, this is done by having a bunch of
static variables that are initialized when needed.
Refactor this to have a function event_init() instead that sets variable in
globalconf (where all of our state should be saved). Also, a preprocessor macro
is introduced to handle event dispatch which also looks a bit nicer.

This reverts commit e6037b4738. It causes many
issues with non-trivial solutions that we first need to come up with. As a
middle ground, we will for now only emit signals if something changes after the
config is loaded.

Instead of querying the wallpaper every time that root.wallpaper() is called, we

This gives us the worst of both worlds: We still restart on RandR screen changes
and the information about screens isn't available during startup. However, it's
a step in the right direction, because all Lua code will now have to handle
kind-of-dynamic screen changes.

The Lua stack is a finite resource and everything that pushes something there
should also clean up. This is not a problem for functions that are called by
Lua, because their "stack frame" is freed when they return. However, in global
context, Lua does not and cannot automatically clean up for us. Thus, it makes
sense to print a warning in this case.
(Additionally, this cleans up the stack if something is left)

_NET_WM_ICON contains a list of icons and until now, the first one was
picked without regard to it's size. This adds a global option to set
the preferred icon size. When getting the client icon, the best size
match is picked. The size can be set via
awesome.set_preferred_icon_size() and the default is 0, which will pick
the smallest non-zero size icon available.

The only exception is the window for _NET_SUPPORTING_WM_CHECK. That window
already had a _NET_WM_NAME property before and doesn't get a WM_NAME property in
this commit. I just decided for myself that it doesn't need one. :-)
Right after startup with the default config we now have the following situation:
$ xwininfo -root -tree
xwininfo: Window id: 0x2d7 (the root window) (has no name)
Root window id: 0x2d7 (the root window) (has no name)
Parent window id: 0x0 (none)
7 children:
0x200011 "Awesome drawin": ("awesome" "awesome") 1500x20+0+0 +0+0
0x200010 "Awesome drawin": ("awesome" "awesome") 1x1+0+0 +0+0
0x20000d "Awesome drawin": ("awesome" "awesome") 100x30+0+0 +0+0
0x20000a "Awesome no input window": ("awesome" "awesome") 1x1+-1+-1 +-1+-1
0x200009 "Awesome systray window": ("awesome" "awesome") 1x1+-1+-1 +-1+-1
0x200008 "awesome": ("awesome" "awesome") 1x1+-1+-1 +-1+-1
0x200007 "Awesome WM_Sn selection owner window": ("awesome" "awesome") 1x1+-1+-1 +-1+-1
One of those drawin is the awful.wibox. Another drawin is created by awful.menu.
I guess that the third one is created by awful.tooltip, but I'm not sure. Wow,
so many windows...

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 is not only useful for soft restarts, but also when TERMinating
awesome during development/testing.
The drawback appears to be that it would leak a property on the root
window in case it is really meant to be quit.
Closes https://github.com/awesomeWM/awesome/pull/374.
This saves the order of clients in a property called AWESOME_CLIENT_ORDER on the
root window during shutdown. During startup, after managing all existing
windows, we force the client list into the order described by this property
(overwriting any changes that Lua possibly did).
This code should safely handle cases where the property doesn't contain all
existing clients or contains a client which doesn't exist anymore.

This improves the behaviour with print()ing for debugging, when the
output is redirected to a file.
I was using `setbuf(…, 0)` initially, but it makes sense to buffer it
per line. This uses `setvbuf` instead of `setlinebuf`, which might not
be available everywhere.

This patch provides functions to get/set current keyboard layout.
Current implementation doesn't support any configuration of layout,
it's a merely a layout indicator and switcher, however layout
configuration can be set by tools like setxkbmap or by any third-party
tools.
Create a pixmap of size 1x1 and a cairo-xcb surface for this pixmap. If the
surface ends up in an error state, awesome will refuse to start.
This turns a "awesome is unusable and prints lots of errors on X11 servers where
the root window has a depth of 8bpp and no one knows where exactly the problem
is" into "awesome refuses to start on such X11 servers and prints an error that
helps Uli to say immediately what the problem is".

The 'request::activate' signal should be sent and handled immediately,
and not delayed. It was too much of a hack to work around the client
not being visible.
Instead, the "is visible" constraint on `capi.client.focus` will be
removed.
This reverts commit 6963ede3dc.
This reparents all clients back to their proper position during shutdown, so
that their top-left corner is now where their titlebar's top-left corner was.
Hopefully, this fixes floating clients moving around across a restart.

Everything that needs the lua_State should create a local variable like this:
lua_State *L = globalconf_get_lua_State();
This ensures that the compiler warns if there are two variables with name "L" in
scope. The idea here is that it should become harder to accidentally use the
global lua state instead of the state of the current state.
While writing this commit, I found another place that gets its wrong: Reading
client.focus from a coroutine was broken, since it was returning the result on
the main thread instead of the current one.

There isn't much of a point in doing all the GetGeometry requests in an extra

First, we reset the signal handler back to the default one when a fatal signal
is received. This should make sure that we never get into an endless loop where
the signal handler causes the signal to happen again.
Then this commit also makes awesome print a backtrace on more signals than
before. Crashing with a backtrace is always better than without. ;-)

This commit makes awesome measure how long all the event handling takes. That
is, this measure the time between waking up from poll and going to sleep again.
If that time is above 0.1 seconds, we print a warning and increase the limit for
this warning to the last duration to avoid flooding messages.
This should help figuring out cases were people do stupid things in their
config, like synchronously contacting an IMAP server and getting the number of
unread mails.

We detect other WMs when we fail to request SubstructureRedirect on the root
window. Previously, the code used an unchecked request and then tried to
cleverly detect if an error occurred. This isn't needed.
Instead, we now use a checked request and use xcb_request_check() to see if any
errors were generated. This also gets rid of a round-trip to the server (one is
still implicitly done by xcb_request_check()).

A drawin's and a client's bounding and clip shape can now be queried and is
returned as a cairo surface. Also, a client window's shape (e.g. xeyes setting
its own shape) can be queried via c.shape_client_bounding and
c.shape_client_clip. All of these properties now emit signals when changed.
(This also silently fixes a bug in luaA_drawin_set_shape_bounding() which forgot
to include the drawin's border in its size calculation)
