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.

Commit 222f0a133c optimised the case where we change the wallpaper
so that we can give the new wallpaper to Lua faster. However, contrary
to what was intended, it also caused another wallpaper update later when
the server told us that the wallpaper actually changed. This was because
the juggling with multiple X11 connections went wrong.
Fix this by using the right connection to actually change the wallpaper.

XCB_CURRENT_TIME really should be avoided as much as possible (see
ICCCM).
However, the screen, mousegrabber and keygrabber code have cases where
they really want up-to-date information / want to activate a grab *now*.
These cases are fine with XCB_CURRENT_TIME since they are not related to
some events.

When setting a wallpaper, we open a second connection to the X11 server
and create a pixmap there. This pixmap is then used as the wallpaper. We
do this so that we can use a "close down mode" called "permanent". This
means that the X11 server will not free the pixmap after we disconnect,
but keeps it allocated. Setting this close down mode is the last thing
that we do on the setup-the-wallpaper-connection before disconnecting.
However, sometimes things didn't work around. The wallpaper was missing
and trying to query it resulted in errors that basically mean "there is
no such pixmap". Thus, the symptoms say that the close down mode did not
work.
This commit is an attempt to fix this. Instead of just flushing before
closing the connection (sending all outstanding requests to the server),
this commit does a sync, which means it sends a request to the server
and waits for a reply. This guarantees that all previously requests were
handled.
The theory here is like this: We send the SetCloseDownMode-request and
then immediately disconnected. If the X11 server notices that we are
disconnected before handling the SetCloseDownMode-request, the request
would be ignored.
This theory is consistent with the symptoms above and in my local
testing this patch seems to fix things, but since the error only
appeared sporadically, I cannot be 100% sure. Still, it all seems to
make sense to me.

In the case where one want to put the cursor at the middle of the
workarea, it is logic to do:
x=screen.workarea.x+screen.workasrea.width/2
However, this can cause floating points. This commit move the
burden back to the C-API so the Lua placement code doesn't have
to add a large number of rounding methods. Given 1 type of rounding
cover a vast majority of use cases for each types of coordinates,
the C-API can take care of it in peace. For the other corner cases,
it is still possible for the Lua code to do the rounding there, but
no longer necessary. The convenstions are:
'x' and 'y': use round (move to the closest point)
'width' and 'height': use ceil (to avoid involontary truncating)
This change catches things like c:geometry { width = -42 }.

This fixes a race where we would keep giving the old wallpaper surface to Lua
when a new one was set, because we didn't get the "wallpaper changed"-event yet.
Fix this by just keeping the surface we use for setting the wallpaper around.

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

E.g. trying to press mouse button 1.5 via root.fake_input() doesn't make sense.
Previously the code silently truncated the number to an integer. Now it

This reverts commit c1cb7883b5.
The cairo surface used for uploading the wallpaper doesn't use a temporary
connection but is on our main connection since commit 5024843e9. Thus, the above
commit broke all of our cairo drawing instead of just making cairo not touch our
temporary connection.
Every .c file has to include the corresponding .h file first to make sure the
headers are self-contained. Additionally, this moves some unneeded includes
around.

Turns out that my rant about "we can't query the pixmap's values" was wrong.
This commit makes awesome use a GetGeometry request to get the properties of the
(old) root window's back pixmap.
This also converts code to p_delete() instead of free() for consistency. Bad me
for doing multiple things in one commit...

Thanks to Michael Stapelberg, there is now a xcb-only port of libXcursor which
does everything we need. This patch switches awesome over to that new library.
Since the only reason for using XOpenDisplay() instead of xcb_connect() was so
that we can use libXcursor, we can get back to that older state again. This
means that this effectively reverts the following commits:
531f8b415c "Added initial support for Xlib cursor themes"
77243cd09a "Add x11-xcb to the pkg-config checks"
779d43fc46 "Don't let Xlib own the event queue"
03759b4847 "Fix keyboard layouts"

Previously, cairo would often have to download the old wallpaper from the X11
server and then upload it again. It did this because it couldn't see that the
two X11 connections involved are actually connected to the same X11 server.
This commit fixes this by setting up the pixmap from our main X11 connection.
This is the same connection that we use for accessing the "old" wallpaper and
thus cairo doesn't have to do stupid things.
The big improvement with this is that this speeds up wallpaper setup a lot.

Some functions didn't check the class of objects they were passed but just
casted them to the type they expected. This lead to code like e.g. the following
to crash awesome:
c.titlebar = c
This adds a new function luaA_object_ref_class() which works like
luaA_object_ref(), but which also checks the class of the object.
Additionally, this function is now used in all necessary places.
