In the case where no CPU number is given, skipping a character of
padding actually skips the null terminator, causing further iterations
through the loop to read out of bounds. Have sscanf() return the number
of characters read, instead of reconstructing it from the CPU number.
This was observed as a failure in test 024-cpu-usage-invalid-cpu.

Currently, the module cpu_usage prints %cpu0 information for the invalid
%cpu placeholder (i.e. the cpu number is missing).
Consider the following configuration.
order += "cpu_usage"
cpu_usage {
format = "cpu0=%cpu0 cpu1=%cpu1 cpu=%cpu"
# missing cpu number -------------------^
}
The configuration above produces the output below.
$ i3status -c config
i3status: trying to auto-detect output_format setting
i3status: auto-detected "term"
cpu0=-2% cpu1=-49% cpu=-2%
cpu0=06% cpu1=02% cpu=06%
cpu0=05% cpu1=06% cpu=05%
...
The module prints %cpu0 at the third placeholder where it should report
an error.
This commit fixes this behavior by initializing `number' to -1. If the
cpu is missing in %cpu placeholder, the sscanf function does not set
`number'. Because `number' is -1 (lower to 0), an error is reported and
the placeholder is skipped.

its now possible to have percentage before and after a variable. except
for the date. But percentage with dates does not make much sense to me, so
i skipped it.

This change addresses the issue #199 asking for multiple CPU support. It
takes an arbitrary CPU number and outputs its usage using the same
arithmetics as for CPU aggregation. It currently doesn't support
FreeBSD.

Add 'format_above_threshold' option for 'cpu_temperature' module
Add 'format_above_threshold' option for 'cpu_usage' module
Add 'format_above_threshold' option for 'load' module

CPU usage had previously not supported the color option. Add support
for a "degraded" state above which the degraded color is used, and a
higher "bad" state above which the "bad" color is used. One possible
use for these might be indicating whether one or all cores are
saturated.
Unlike the color settings for other, these are set high enough to be
disabled by default. This is done because i3status determines CPU
usage over only the last display interval, which means that, a user
with a low refresh rate might see frequent, potentially-annoying color
changes.

From here on, we’ll use clang-format to automatically format the source.
This has worked well in i3, so we are introducing it for i3status.

* strncmp(s1, s2, strlen(s2)) → BEGINS_WITH(s1, s2)
* strncmp(s1, s2, strlen(s1)) → strcmp(s1, s2)
* Prefer case-insensitive comparison for options

i3status (Thanks Artemis)
The former made i3bar crash, the latter is helpful for debugging.

This hardcodes all the JSON parts. Strings are not properly escaped currently.
The best/easiest way to fix this is by actually using libyajl.
