The basic plan here is to fix reloads to be more stable
using read/parse/verify/build/commit stages, so that any errors
will not leave corosync in an unstable state. This should
also make the code more maintainable as currently the verify/commit
stages are horribly intertwined.
Also:
- Fix local_node_pos not being updated in the new map during validation
(broke adding and removing new nodes in the middle of the list).
- Fix reconfiguration so that nodes are indexed by nodeid and not their
position in the list. This is an old bug that's just been carried
over
