  o Minor features:
    - Check for and recover from inconsistency in the microdescriptor
      cache.  This will make it harder for us to accidentally free a
      microdescriptor without removing it from the appropriate data
      structures.  Fixes issue 3135; issue noted by wanoskarnet.
Track where microdescs are referenced to prevent free errs On IRC, wanoskarnet notes that if we ever do microdesc_free() on a microdesc that's in the nodelist, we're in trouble. Also, we're in trouble if we free one that's still in the microdesc_cache map. This code adds a flag to microdesc_t to note where the microdesc is referenced from, and checks those flags from microdesc_free(). I don't believe we have any errors here now, but if we introduce some later, let's log and recover from them rather than introducing heisenbugs later on.
