redboot patches

Hi, we are using RedBoot with MCUs with embedded Flash to load the code into
that embedded Flash and execute from there. For those targets there are usually
two constraints with Redboot:
- internal Flash blocks are not of uniform size and therefore adresses are more
difficult to calculate (walk the table instead of a simple division)
- internal RAM size is very limited, often static memory allocation is
prefered.

The patches in the attachement address those two restrictions.
