FreeBSD changes (#327)

* llabs() is included in FreeBSD since FreeBSD 5.0.

Oldest supported FreeBSD version is 9.3 now.

* stdio.h needs to be explicitly included here for FreeBSD.

I can wrap it in #ifdefs if needed, but I don't think it can hurt other OSes.

* addr config variable works fine on FreeBSD.

* FreeBSD 5.x is really an ancient version and long unsupported, so I think this check for it can be dropped.

* Fix and simplify code to get battery state and charge.

* Add required include on FreeBSD.

* Add needed include on FreeBSD.

* Also populate basename to avoid printing (null) process names.
