Changes to all parts of the project:

Size optimizations.
Added a define (EXCLUDE_FROM_XTIDECFG) to exclude unused library code from XTIDECFG.
Tried to minimize time spent with interrupts disabled.
Some minor attempts to improve speed (reordering instructions etc).
Tried to improve readability, did some cleanup and fixed some errors in comments.
