Created Bitfield functions (auxdebug on) [2012-02-21]

WARNING!!

All commits upto and including the commit of [2012-05-13] contain
a severe bug!! Building from these sources and then disabling
the 'force LBA' feature while also using the drive-letter feature or
editing the label can DESTROY THE MBR on ALL ATTACHED DISKS!!
DO NOT DISABLE 'FORCE LBA USAGE' WHEN BUILT FROM THE THESE COMMITS!!

New

o Functions to insert/retrieve bitfields

Let's see if we can compress the hideparttable...

26; This module contains functions for debugging AiR-BOOT.
27; It is only included in debug builds and the codesize of AiR-BOOT increases
