When using Pango to draw text in i3bar, the y-offset of the text is
incorrectly calculated in case all characters in the string to draw are
smaller than the cached font height. Fixes#1494.
Parse text within workspace buttons and the i3bar statusline as Pango
markup. This lets people specify things like font weight, text color,
background color, font size, and font family in the text of i3bar.
fixes#1468
When loading a new font with `load_font`, free the previously loaded
font with `free_font`.
If no font is loaded, `free_font` will simply return (instead of
crashing because of a double free).
We're going to call parse_configuration() very early if -C is given on
the command line. Instead of the previous "only_check_config", which has
been a global variable, we now simply pass use_nagbar as false if we're
just validating.
This causes the whole parsing to run without X and of course without
starting nagbar and displaying the errors to standard out/error instead.
The return code of parse_configuration() is now a boolean which
represents whether an error occured during parsing and the programs exit
code is returned accordingly.
Although the config parser still has a lot of side-effects, we now can
parse without the need to have an XCB connection. A nicer implementation
would be to just set the new font and load it just after we're done
parsing, but to ensure we don't break functionality we just load a dummy
FONT_TYPE_NONE if XCB isn't available. The main reason for going this
route is that it's a bit difficult to test fonts in a distribution
agnostic way without bundling fonts with i3 (or Xdummy to be more
exact).

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.
Receiving EOF from a client is not an error, but rather a standard way a
client may disconnect from the IPC. This should rather be logged from
a consumer of the libi3 ipc_recv_message() function as a normal client
disconnect event.

This avoids flooding stdout every time some text (e.g. a window
decoration) is drawn, yet leaves the message in place when it’s actually
relevant (upon DPI changes).
fixes#1115
Since the macro PATH_MAX is not defined on every system (GNU/Hurd being
one of those who do not define it), we remove all references to this
macro. Instead, we use a buffer of arbitraty size and grow it when
needed to contain paths.
This removes code duplication, which will be useful for a subsequent
commit.
Furthermore, we now don’t open X11 connections unnecessarily in some
corner cases.
The pango font specification accepts a font size in points, but pango
defaults to a DPI of 96. Create a default PangoContext (which
internally creates a default PangoCairoFontMap as usual) and set the
DPI to the value of the root Screen manually.

When drawing a text with Pango, shift it to the top according to the top
if the glyph if taller than expected
We always shift of (height - savedHeight) which is a no-op for normal glyphs

Without this fix, children of i3bar would inherit the file descriptor of
the IPC connection to i3. Therefore, even if i3bar exits with SIGSEGV,
the connection to i3 stays open. Because nobody actually reads any
messages by i3, the buffer will fill up and i3 can’t deliver any more
messages, and thus busy-loops at that point.
fixes#995
Use the following command to reproduce this bug:
echo 4096 | sudo tee /proc/sys/net/core/wmem_default
Then just switch workspaces with some windows on it and i3bar would
exit due to malformed IPC messages.
This bug hits OpenBSD users (and possibly other BSDs) due to their lower
default buffer size.
fixes#896
While this is a bit ugly, it makes the log messages end up where they
are supposed to: in the shmlog/stdout in case of i3 and on stdout in
case of utilities such as i3-input
