Unify several ways to tracking backend type
Add a new global variable MyBackendType that uses the same BackendType
enum that was previously only used by the stats collector. That way
several duplicate ways of checking what type a particular process is
can be simplified. Since it's no longer just for stats, move to
miscinit.c and rename existing functions to match the expanded
purpose.
