libnm: fix up class struct reserved slots

Add reserved slots to those classes that were missing them (or had run
out), and sync up the number of slots across classes:

  - 8 slots for "important" classes, abstract base classes, and
    classes we expect we might need to add new virtual methods or
    signals to later.

  - 4 for everything else

Also, rearrange the class elements in a few places into standard order
(signals first, then methods).
