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.

The getters for properties already get the object as their second
argument, so there is no need to get the object again from Lua.

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.

Aborting the process is sometimes a bit harsh for a failed assertion.
This adds a non-fatal assert() macro called "check()" and uses it in
some places where we might be able to survive the error.

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.

The code in luaA_client_swap() is incorrect, because
luaA_object_emit_signal() already pops the arguments to the signal.
Still, the code here tried to remove the arguments from the Lua stack
again, thereby corrupting the stack (removing more items than there are
in the stack).
Normally, popping more things from the stack than it has entries
silently corrupts the Lua stack. Apparently this doesn't necessarily
cause any immediate issues, because this code has been broken since nine
months and no one noticed. This mistakes was introduced in commit
55190646.
This issue was only noticed by accident. Thus, this commit also adds a
small integration test that exercises this bug. This test catches the
issue, but only on Travis, because there we are building our own version
of Lua 5.3 and that one has assertions enabled.

Daniel sees a short flicker of his wallpaper when he closes a client.
This happens because the window is destroyed immediately, but other
clients are re-arranged only shortly later. In the mean time, the X
server updates the display and repaints the root window (= wallpaper
becomes visible).
Work around this by delaying the destruction of frame windows to the end
of the current main loop iteration. This means that we first update the
position of all other windows and later destroy the window that was
actually closed.

There are some situations where we do things that can make the mouse pointer
enter another window. We do not want to react to these "self inflicted" mouse
enter and leave events, because they aren't "real" (= generated by the user).
Before this commit, this is done by going through all windows and toggling the
"please send us enter and leave events"-bit on them. This becomes slower when
many windows are visible and floods the server with requests.
This commit changes this to a constant-time logic. Each event contains the
sequence number of the last request that the X11 server handled. Thus, we just
remember the right sequence numbers and ignore any events that comes in whose
sequence number falls into the ignored range.
In detail, we keep a list of "begin" and "end" sequence numbers and ignore any
enter and leave events that fall in this range. If we get any event with a
sequence number higher than "end", we remove this pair from the list, since it
is no longer needed.
To generate these pairs, we use a GrabServer request in
client_ignore_enterleave_events(). This gives us a sequence number and makes
sure that nothing else besides us can cause events. The server is ours! In
client_restore_enterleave_events(), we first do a NoOperation request to
generate the sequence number for the end of the pair and then do UngrabServer.
Any event that is generated after UngrabServer will have at least the sequence
number of the UngrabServer request and thus no longer fails between begin and
end.

This commit makes the function only call client_ignore_enterleave_events() when
it actually has to. Since we expect that most of the time, no client's geometry
is changed, this means that most of the time this function is not called.

This should "protect" the user from some stupidities that Lua code might be
doing that e.g. makes a client jump to another position and then immediately
back to where it was before. Only the last change in a single main loop
iteration will actually have any effect.

A client c could have no c.machine or no c.pid because the corresponding
properties are not set on its window. Previously, the C code would return an
empty string or 0 for these values. This commit makes the C code give Lua no
value instead (not even a nil).
