Reworked Special Partition Handling [2011-11-24]

Changes

Changed the special partitioning handling code to be more aware
of what kind of partition we're dealing with. This is debug-code.
Most of the added functions are actually redundant and are removed
in later revisions.

Note

This commit and all following commits upto and including the RC3
commit [2012-09-09] are delayed commits from a local repository.
Also, the RC (Release Candidate) naming of the corresponding commits
is a bit misleading. One would label a revision with RC when near to
a final release. Since many things have changed between RC1,RC2 & RC3,
these RC's should be interpreted as mile-stones.

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 ABOVE COMMITS!!
