Hi all,

In preparation for adding block headers and enforcing endian order in
rtbitmap and rtsummary blocks, replace open-coded geometry computations
and fugly macros with proper helper functions that can be typechecked.
Soon we'll be needing to add more complex logic to the helpers.

v1.1: various cleanups suggested by hch

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

With a bit of luck, this should all go splendidly.
Comments and questions are, as always, welcome.
