This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *

This is a bit updated set of chain.c32 changes that simplifies a few things (and in partiter part), fixes few minor issues and adds a few new features. Details are in the following commits, below is the summary and pull details at the end. Shao - any chance to peek over them ? Most of those are relatively simple changes and well tested, though of course something might have slipped my attention.

1) code split and move Iterator related functionality is yanked from chain.c and moved to iterator.{c,h}. Both are moved to com32/chain and this way chain.c is ready for further splitting. Alternatively, partiter could be moved to com32/lib at any time in the future. It's potentially useful for other modules (e.g. if someone wanted to code partition dumper or editor). 2) Iterator updates
