The current implementation uses the wrong type for
given sysctl calls leading to overflow and incorrectly
reported RAM usage. The fix is to use 'unsigned int'
which is what FreeBSD expects.
Adding a new keymap component that will
indicate the current keyboard layout (language)
and variant if any was set. I use the
standard X11 XKB APIs to retrieve and parse
the xkb_symbols set with setxkbmap.
