Instead of using Xlib for parsing resource files, this now uses the
dedicated xcb-based library that is meant for exactly this task.

Via this, I can set HEADLESS=1 in my wrapper-GNUMakefile that I use and
"make check" will no longer open a new window that gets in my way.

Similarly to what we do with the client list, this signal is emitted
whenever the list of screens changes.
Signed-off-by: Uli Schlachter <psychon@znc.in>
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.

The usual "a or b"-trick to simulate C's ?:-operator does not work when
"false" is a valid value. Fix the code to handle this correctly and add
a short unit test which would have caught this problem.

We already have a variant of this function for transforming an actual
matrix. This adds the corresponding static factory.

Instead of doing Linux-specific magic with error codes and trying to
read the first byte of a file, just use Gio to check if a file exists
and is readable.

When adding callbacks as a `callback` entry in a property, the callback
is run by `awful.rules`, because it does `c.callback =
result_of_function`. This is obviously not intended. Also, this causes
the callbacks to run twice, because the code already handled this
`callback` property specially.
Fix this by just not merging callbacks with the normal rules at all.

Instead of hardcoding the list of generated doc files as dependencies to
ldoc, we jump through some hoops to compute this dynamically.

A while ago, we made errors from ldoc fatal by default. Then a new ldoc
release appeared and caused problems for all of our users, because
awesome failed to work.
This patch reverts the previous fix so that we ignore ldoc warnings by
default again. However, to catch ldoc warnings on Travis, another
ldoc-building-target is added that fails on warnings. This new target is
included in our "check" target.
This fixes the intend of issue #1098 ("Users with ldoc version X cannot
build awesome"), but it does not actually employ the solution proposed
there ("Blacklist those ldoc versions"). Still, since this fixes the
intend of the issue, I count it as fixed.

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.

Add a single "do" to the beginning of the config. This causes a parsing
error ("'end' expected") and then another warning saying "something was
left on the Lua stack.
Fix this by popping the error message where we need to do so.

For some reason, the code here tried to handle widget::redraw_needed
signals even though it should apparently/obviously only produce a
current snapshot of the widget's look.
Fix this by just removing the redraw code.
While here, also factor out the widget context table into a local
variable and re-use it for the initial layout and for the later draw.

When awesome calls any Lua code, it does so with a protected call. This
means that any kind of Lua error should (there are exceptions) just
result in an error message being printed and everything continuing as
usual. When LGI calls Lua code, it uses a normal call. This means that
in an asynchronous context, that is, when there is no more call
generated by awesome's C code on the call stack, we must be careful,
since any error results in Awesome's unprotected error handler to be
called which restarts the WM.
menubar.utils.parse_dir() asynchronously parses a directory containing
.desktop files. This means that it is no longer in a protected call
context. Let's assume that the code itself is fine. However, the
callback that the caller provided for handling the results can be quite
arbitrary. Make sure that it is run in a protected context.

It does not provide much value. The version number is already known to

This is necessary when being run with a tty that has no width, which
happens when using https://github.com/metakirby5/codi.vim/ in Vim 8 (but
not Neovim), where rlwrap complains as follows:
> rlwrap: error: My terminal reports width=0 (is it emacs?) I can't
> handle this, sorry!
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.
