46c4540dd2 Implement fmt_human_2() and fmt_human_10()
These functions take the raw number and a unit and automatically
print it out "scaled down" to a proper SI-prefix, for powers of 2
and 10 respectively.

Apply them to the 2-power cases and keep the 10-power for a later
commit.

80fc20d1d6 Add warn() and die()
Given slstatus is a tool that runs in the background, most likely run
from .xinitrc, it's important to prepend the name of the tool to error
messages so it becomes clear where the error is coming from.

To make this much more consistent, this commit adds warn() and die()
utility functions consistent with other suckless projects and adapts all
calls to fprintf(stderr, *) to the warn() and die() functions, greatly
increasing the readability of the code.

ee5ec75621 Fix coding style
- Use block for single statement ifs
- Keep lines to reasonable length (current debate as to reasonable)
- When functions return -1 for error test against 0 not -1
- Do not indent cases another level
- Do not test against NULL and 0 explicitly
- Use tabs for indentation, use spaces for alignment

Make use of strerror(errno) and format all errors equally:
function ['parameters']: error message

96f3a8a54e Get rid of err.h as it is not portable
Replace warn() and warnx() with fprintf() and add <stdio.h> where
necessary.

Move components into dedicated subdirectory
This brings us a lot more tidiness.
