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,

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.

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.
