Total memory would go out of bounds for machines ~ > 3.5gB of
memory due to the limit of what u_int can hold.
Use ``getpagesize()`` and bitshift pagesize so it fits.

- Instead of displaying hardware ram quantity, display ram available to be
allocated by applications. FreeBSD uses some ram for kernel, segment mappings
and other stuff. Those memory pages are not available for allocation by
applications.
- Calculate correctly ram usage. Active + Wired (buffers). Nothing else.

htop on FreeBSD uses linux procfs compatibility layer, and thus it's readings
are a little off.
- Removed OpenBSD stuff from freebsd port
- Renamed bsd folder to freebsd since now it contains only
freebsd-relevant files.
- Changed CMake instructions to account for bsd port changes
- modified main source file to account for openbsd port
