Clean up the "Region 1" related definitions, and define load addresses, max load size, and max total size for as many boot block types as we can. (types = unified, primary, secondary). We can't always define all values for all boot blocks, though. Make CPP flags selection less gross. Use objcopy rather than headersize (yay, evil gets a stake to the heart!). Use a little shell script to verify that the sizes of the boot blocks are OK. Do not compile too much more of libsa than we actually have to.
