Fixes for undefined behaviour on signed shift
Change literal 1 to unsigned to allow safe bitshift of 31.
Caught by cppcheck.
Make 0xFF unsigned to prevent a left shift into signed bit.

This fixes a new warning from GCC 8.1, -Wstringop-truncation:

Replacing with memcpy is what gcc suggests:
> As another example, the following call to strncpy results in copying
> to d just the characters preceding the terminating NUL, without
> appending the NUL to the end. Assuming the result of strncpy is
> necessarily a NUL-terminated string is a common mistake, and so the
> call is diagnosed. To avoid the warning when the result is not
> expected to be NUL-terminated, call memcpy instead.
> void copy (char *d, const char *s)
> {
> strncpy (d, s, strlen (s));

i3bar’s X11 output is not what our testcases are testing — the state
manipulations which i3bar triggers via IPC messages to i3 are what we are
interested in.
As of 2f0f8b1, i3bar will properly clean up on output change events.
However, this requires us to query the workspaces again to avoid a
display error in i3bar.

Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
This disables the default leak-check-on-exit behavior which reports a
bunch of leaks that are only leaks while exiting, at which point they
don’t matter, because the operating system will clean up the memory our
process used.
1. Add a function writeall and make swrite wrap that function. Use either writeall or swrite, depending on whether we want to exit on errors or not.
2. Fix warnings when compiling with a higher optimisation level.

Dynamically update the font when the `reload` command is called by
reloading the font with `xcb_init_late` and adjusting the size of the
bar by updating the output dimensions with a call to the ipc.
This should be the last commit that formats a big bunch of files. From
here on, whenever I merge patches, I’ll run clang-format like described
in the title.
This has multiple effects:
1) The i3 codebase is now consistently formatted. clang-format uncovered
plenty of places where inconsistent code made it into our code base.
2) When writing code, you don’t need to think or worry about our coding
style. Write it in yours, then run clang-format-3.5
3) When submitting patches, we don’t need to argue about coding style.
The basic idea is that we don’t want to care about _how_ we write the
code, but _what_ it does :). The coding style that we use is defined in
the .clang-format config file and is based on the google style, but
adapted in such a way that the number of modifications to the i3 code
base is minimal.
If a command is passed to `start_child` which is NULL, such as in the
case when there is no `status_command` specified in the bar config, do
not start a child process to listen on stdin.

When connecting or disconnecting an output, i3bar reconfigures its
windows. This also included an unmapping of the bars, and a remapping of
all docked bars. Thus, the bars were misplaced when a monitor was
disconnected.
This commit assures that the remapping of the bars only takes place,
when the mode has actually changed. This patch also takes care of an
inconsistency when pressing the bar_modifier while switching the mode.
Also, the xkbDisplay is now closed correctly, when deregestering the xkb
keyevents.
The hidden_state and mode of each i3bar instance can now be controlled from within i3.
Therefore, two new i3 command were introduced:
_
bar hidden_state show|hide|toggle [<bar_id>]
show: always show the bar
hide: normal hide mode
toggle: toggle between show and hide (individually for each bar)
_
bar mode dock|hide|invisible|toggle [<bar_id>]
hide,dock: like before
invisible: always keep the bar hidden
toggle: toggle between dock and hide (individually for each bar)
This patch introduces a hidden_state ("hidden_state hide|show") in the
barconfig, which indicates the current hidden_state of each i3bar
instance. It only affects the bar when in hide mode. Additionally, a new
invisible mode was introduced. In order to change the hidden_state or
mode of the bar from i3, a barconfig-update event was introduced, for
which a bar can subscribe and the bar then gets notified about the
currently set hidden_state and mode in its barconfig.
For convenience, an id field ("id <bar_id>") was added to the barconfig, where one can
set the desired id for the corresponding bar. If the id is not specified, i3 will
deterministically choose an id; otherwise, with the previous random approach for finding
a new id, which is actually not shared with i3bar, as it would determine its id on
startup, the event-subscription would be destroyed on reload. Still, this issue remains
when manually changing the bar_id in the config and then reloading.
fixes#833, #651
In order to not duplicate configuration options and make stuff confusing, we
dropped the commandline flags (except for socket_path and bar_id). This means
that you *have to* specify bar_id when starting i3bar. The best way is to let
i3 start i3bar, which it will do automatically for every bar {} configuration
block it finds.
