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.

Add `markup` to the i3bar protocol as a block member.
This is a string that determines how the block should be parsed as
markup. "pango" indicates the block should be parsed as Pango markup.
"none" indicates the block should not be parsed as markup.
A buffer is introduced for the statusline which will only be copied to the actual statusline
once an entire statusline is parsed. This avoids a race condition where incompletely parsed
statuslines were rendered, causing only some status blocks to be rendered which is visible to
the user as a flickering.
fixes#1480
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.

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.
Wait for the child process to exit on its own before freeing
watcher-related resources.
i3bar shows the last received status line until the process exits.
Fixes a race condition where the termination signal was sometimes not
received to display a meaningful error message.
When the `status_command` sends EOF, it is terminated. Terminating this
process prints an error message to the status line (hence, a race
condition). This error message is always more useful than the former
"EOF" status line error because it shows the exit code.
Exit 127 can be returned by the shell when the command is not found or
when the `status_command` process returns 127 because of a missing C
library dependency.
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.
fixes#1140
Add a function to i3bar to print an error message in the status line
when the child process invoked by status_command fails to provide
input that can be displayed as a statusline.
When the child provides JSON that cannot be parsed, alert the user and
convey a short message provided by yajl communicating the specific
problem.
When the child (or the shell executing the status command) exits
unexpectedly, alert the user and display the exit code. The cases where
the status command is not executable or not found in the user's PATH are
treated specially.
fixes#1130
Set the process group id of the child process by calling `setpgid` after
forking and before calling `exec`.
The process group ID will be set to the process ID of the forked
process. Processes spawned by this child process will also have this
group ID.
Send signals to the process group with `killpg`. This will send the
signal to all of the process group.
fixes#1128
