Add scanlib for producing keyboard scancodes

Browse Source 
Add scanlib, a library for turning characters into keyboard scancodes
which are needed for scripted keyboard input to VirtualBox VMs.

The keyboard scancode strings returned by this library consist of groups
of two or four hex bytes: two for a key pressed and released, four if a
modifier key such as shift is involved.

The char2scancode function is complemented by two functions for special
keys, esc2scancode and enter2scancode.

# The functions in this library are used to get scancode strings for VirtualBox
# keyboard input (keyboardputscancode).
#
# It was generated mostly from output of Cameron Kerr's scancodes.l:
# http://humbledown.org/keyboard-scancodes.xhtml
#
# The library works with bash 3.2 (shipped with Mac OS X as of 2014).
