Properly declare buf as extern and fix all unused-warnings

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

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.

Implement esnprintf() and make formatted calls more efficient Within the components, snprintf() was unchecked and had inefficient calls in some places. We implement esnprintf() that does all the dirty laundry for us and use it exclusively now.

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.
