The toggle/show/hide function were incompatible with the current
`rc.lua` is `titlebars_enabled` was removed from the rules because
they were never created. This has always been the case but the
introduction os `request::titlebars` in Awesome 4.0 allows to solve
this longstanding issue. However until now it didn't.
Fix#2419
If the history file (or its parents) can't be created, running a command
will fail entirely. Since saving command history is not an integral part
of running a command, it would be nicer if it carried on, just without
saving history. This is what shells usually do.
This patch removes assertions in the history saving function and
instead adds an early return, so if the history isn't saved the command
invocation simply carries on.

This commit adds a way to leverage the xproperty and startup_id APIs
to persist an execution token across restarts. It allows to use
`awful.rules` on clients that were executed by a previous Awesome
instance.
The main limitations of these methods is the lack of entropy used to
build the token. If the command is the same in multiple
`awful.spawn.once`, then it will not work as expected. To mitigate this
issue, the system try to concatenate the `awful.rules` table after the
command and hash the resulting string. Given rules are a table, it can
have loops and/or issues with keys ordering. The hash function sort and
limite recursion to prevent a stack overflow. Another issue is the
unreliability of startup notifications.
`pairs` order isn't defined and `{...}` will always be ordered.
There is no reason to have random behavior where it can be
predicted at no additional cost.
Test that the placement function used in the default configuration
behaves as intended. This test was failing before the no_overlap and
no_offscreen fixes in two previous commits.

The awful.placement.no_offscreen function did not work properly when
composed with other placement functions; in particular, the default
configuration (awful.placement.no_overlap+awful.placement.no_offscreen)
was broken. The compose function sets args.pretend=true and puts the
result of the previous placement function into args.override_geometry
before calling the next placement function, but no_offscreen did not use
args.override_geometry, therefore the result of the previous placement
function was discarded.
All other placement functions use `geometry_common(c, args)` to get the
current client geometry; `area_common(c)` should be used only when
getting geometry of other clients.
This change also fixes the problem with margin handling (adding margins
should not affect the window size, only the window position should
change); the test output which was adjusted in commit 0275d3537d
is adjusted again to account for this change.

The awful.placement.no_overlap function was adding the window border
width to the client width and height (this is performed in
area_common(), which is called by geometry_common()), but did not
reverse this operation by calling remove_border() before returning the
final geometry; because of this, using no_overlap resulted in increasing
the window width and height by 2*border_width.
The bug was probably introduced in commit ebcc19844e (before
that commit no_overlap changed the window position directly instead of
relying on the new placement infrastructure), but was not noticed
because of other problems (e.g., in the default configuration the result
of no_overlap was overridden by the buggy no_offscreen).

The current taglist/tasklist allow filter function to remove elements
from the list. However they don't allow sorting or additional entries
to be listed.
This commit introduced such a concept. It will later be used by the
layoutlist where it becomes more relevant since layouts are used created
"objects".
This property is based on Motif WM hints and checks if the client
requests that it is not decorated with a titlebar.

Commit fec8d6aa8f fixes awful.placement.no_offscreen to behave
like other placement functions. This means that the margins=40 argument
that this test used and that was previously was just ignored, now
started working. Thus, there are now 40 pixels less on each side of the
client in this test.

When poll() is interrupted because of a signal, it sets errno to EINTR.
GLib ignores this kind of failure.
However, a_glib_poll() calls a_xcb_check() at its end. This will call
xcb_poll_for_event() which internally might call recv(), which can fail
with EAGAIN if no new events are available. Thus, a_glib_poll() will
return an error and set errno to EAGAIN. This leads to the following
error message being printed by GLib:
GLib-WARNING: poll(2) failed due to: Resource temporarily unavailable.
Fix this by preserving the errno from g_poll() in a_glib_poll().

GLib is very careful not to "fetch" any children that it was not asked
to fetch. Thus, if awesome inherits some children, it does not reap them
and starts collecting zombies.
Thus, this commit makes awesome handle SIGCHLD directly: On SIGCHLD, a
byte is written to a pipe. The main loop reads from this pipe and
collects children via waitpid(-1). Unknown children cause a warning to
be printed. We might want to remove this warning if it turns out to be
annoying.
This commit adds 79 lines and removes 89 lines. Thus, this is a net
reduction in lines of codes. This is because previously, we gave the
list of still-running children that we know about to the next awesome
instance we a --reap command line argument. This was added so that
awesome does not get zombie children. However, this commit fixes this
problem and makes all the code for this 'feature' unnecessary.

c->size_hints.win_gravity only contains something valid if the
XCB_ICCCM_SIZE_HINT_P_WIN_GRAVITY bit is set in the flags. Most likely
this wasn't noticed before, because most code just happens to
zero-initialize this field and gravity 0 is NorthWest, which does not do
anything.

The function window_set_border_width() causes its own gravity handling.
Thus, to make sure that this gravity handling does not interfere with
what the code in here does later, we just apply changes to the border
width first, and then do everything else.
Signed-off-by: Uli Schlachter <uli.schlachter@informatik.uni-oldenburg.de>
Before this commit, the code in here first handled clients changing its
x/y position and afterwards it handled resizes. This meant that the
special case of "client resizes without moving itself so we need to
apply gravity" had to have special checks on whether the client moved
itself or not.
Change the code so that resizes are handled first and moves later. This
naturally handles the problem: If the client resizes and moves itself,
the move done for the resize is later overwritten when the move is
handled.
No functional changes are intended.
