This comes with the intentionally undocumented --disable-randr15 command
line flag and disable-randr15 configuration directive. We will add
documentation before the release if and only if it turns out that users
actually need to use this flag in their setups. Ideally, nobody would
need to use the flag and everything would just keep working, but it’s
better to be safe than sorry.

This tool is similar to xtrace in usage in that it intercepts traffic to
the X server. The motivating feature for writing the tool is its ability
to inject prepared reply messages instead of the server’s reply. In
this particular case, we’ll inject a RRGetMonitors reply to test i3’s
RandR 1.5 code paths.
The added testcase is a noop for now, but with the code that’s lingering
in the randr15 branch, i3 does actually detect monitors as per the
injected reply:
2016-11-20 21:10:05 - randr.c:__randr_query_outputs:618 -
RandR 1.5 available, querying monitors
2016-11-20 21:10:05 - randr.c:__randr_query_outputs:628 -
1 RandR monitors found (timestamp 0)
2016-11-20 21:10:05 - randr.c:__randr_query_outputs:646 -
name DP3, x 0, y 0, width 3840 px, height 2160 px, width 520 mm,
height 290 mm, primary 1, automatic 1
This is preparation work for issue #1799
Fix memory leaks when executing 'i3 --moreversion'.

SUMMARY: AddressSanitizer: 198 byte(s) leaked in 3 allocation(s).
https://llvm.org/bugs/show_bug.cgi?id=30353 was filed for the unintended
line break between in e.g. “TAILQ_ENTRY(foo)\nbar;”.
Until that’s fixed or a workaround is known, we’ll live with line
breaks. To make it a bit easier for readers to see what’s going on, I
added extra line breaks around each such struct member/variable
definition, so that they at least visually are a single unit.
fixes#2174
Without the prefix, the etc/ directory will be copied from the source
directory, as opposed to the debian/tmp directory into which files were
installed.
Fix the issue #2421 (https://github.com/i3/i3/issues/2421).
floating_enable() invokes tree_close_internal() to free con->parent.
After con->parent is freed in tree_close_internal() but before con->parent is reassigned by the caller, con->parent may be dereferenced and causes i3 crash.
The backtrace below is an example.
The already-freed pointer is dereferenced again through the pointer "focused" in x_push_changes().
Reassign con->parent before calling tree_close_internal() to fix this use-after-free bug.

I3_VERSION is used as string literal in config.h, i.e.:
#define I3_VERSION …
Where “…” is replaced with the contents of I3_VERSION.
For our travis builds, we persist the version number to I3_VERSION,
i.e.:
$ cat I3_VERSION
4.12-150-g8ddc187 (2016-10-25, branch "next")
Previously, config.h would end up with:
#define I3_VERSION "4.12-150-g8ddc187 (2016-10-25, branch "next")"
Note the unquoted double quotes around “next”, which are invalid in
C string literals.
Hence, this commit uses sed to escape double quotes, question marks and
backslashes (see also http://stackoverflow.com/a/12208808/712014).
The @<:@ and @:>@ quadrigraphs that m4 expands to [ and ], respectively,
see also http://stackoverflow.com/a/2309394/712014
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.
