eapi: Improve sub-slot and slot operator documentation, bug #446740
Add sub-slots to the Slotting chapter. Update the slot name sections
to match current portage versions (as noted by Arfrever). Add slot
operators to the Dependencies chapter, and describe sub-slot
dependencies (as suggested by Arfrever). Rephrase the slot operator
documentation in the EAPI Usage chapter to be a bit more readable
and a bit less PMS-like, explain sub-slot dependencies in more detail,
and add brief examples.
