These caches, well, cache the result of the :layout and :fit callbacks on
widgets.
Clearing caches is done by recording dependencies between a widget. When a call
to base.fit_widget() or base.layout_widget() recursively causes another call to
such a function, this means that the earlier widget depends on the later widget.
This dependency is recorded and when the later widget emits
widget::layout_changed, the caches of all the widgets involved are cleared.

This makes the tests for wibox.hierarchy use test_utils.widget_stub() instead of
having its own implementation of "fake widgets".

A widget hierarchy describes the position of widgets. The hierarchy is a
recursive tree of widget hierarchy instances. This functionality depends on a
:layout function that is not yet implemented on widgets, but will be added
later.

This new function spawns a program, similarly to awful.spawn, but captures its
output. On each line of output on stdout / stderr, a Lua function is called with
this line. There are different callbacks for stdout and stderr. When both stdout
and stderr are closed, another callback function is called. The intention for
this last callback is "the program is done", because most programs should only
close their output when they exit.

This allows the "label" callback to adjust the textbox itself.
`tasklist_label` is changed to make use of it and supports new style
arguments: `font_focus`, `font_urgent` and `font_minimized`.

From http://standards.freedesktop.org/wm-spec/latest/ar01s05.html:
> _NET_WM_STATE_FULLSCREEN indicates that the window should fill the
> entire screen and have no window decorations. Additionally the Window
> Manager is responsible for restoring the original geometry after a
> switch from fullscreen back to normal window. For example, a
> presentation program would use this hint.
awesome prefers fullscreen internally already. With this patch, the
previous maximized state will be restored after leaving fullscreen mode.

This tried to use awful, but didn't load awful itself. Kids, this is why you
should make your variables local!

After this change, fit_widget() enforces that a widget cannot ask for more space
than was offered to it. This also fixes a rounding issue in the flex layout
where its fit function would return too small numbers.
Thanks to this, lots of "XXX" comments in spec/ disappear.

In expand nodes "none" and "outside", the variable size_remains describes how
much space is available for the first/third widget. Everything else is used by
the second widget. Thus, fitting the second widget to anything involving
size_remains is wrong. Instead, this commit uses the correct value.
This also fixes a messed up argument order for horizontal align layouts.

The tooltip might be partly outside of the screen, and especially the
workarea, e.g. for tooltips on the tasklist.
Calling `awful.placement.no_offscreen` makes sure that it is fully
inside, and will even restrict it to the workarea, not only to the screen.
Closes https://github.com/awesomeWM/awesome/pull/409.
When using Xephyr, this already starts the server with -noreset, but for Xvfb we
also need this flag. Without this flag, the DPI value that is set via xrdb gets
lost at server reset.
This wasn't a problem before commit 6d4837a53a. That commit moved the launch
of the dbus session after the setting of the DPI. So previously, waiting for
server startup was half broken (the dbus session already tried to connect to the
server to check for when it shuts down), but due to this no server reset
occurred and thus the DPI was correctly applied. After this commit, the server
immediately resets after xrdb is done setting the DPI and the value set is lost.
