datetime: Add <stdio.h> for fprintf

#include <stdio.h>
Split into multiple files For multiple reasons the program is now split: - Make future porting to OpenBSD easier - Assign header includes to individiual functions - Make future program extensions easier - Recompile only changed parts

#include <time.h>
Move components into dedicated subdirectory This brings us a lot more tidiness.

#include "../util.h"
components/*.c: include slstatus.h this gives the compiler a chance to check weather the prototype and definiton matches or not, which would catch issues like 3c47701.

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

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.
