Reduce RAM usage in CMS

Browse source 
Add support for direct pointers to readonly values rather than using
intermediate OSD_XXX_t types.
Use direct pointers on all readonly values.
Make sure all intermediate value/step holders are in flash rather
than ram, since they're never modified.

This saves another 352 bytes of RAM (mostly on data, a few on bss).
