  Protocol between inotify clients and server:

Client sending query:
  1) send protocol version number
  2) send query type (string, 4 letters long)
  3) send query parameters:
     - For STAT, N+1 \0-separated strings:
        1) N different names that need checking
        2) 1 string containing all the status types to match
     - No parameter needed for DBUG

Server sending query answer:
  1) send protocol version number
  2) send query type
  3) send struct.pack'ed headers describing the length of the content:
      e.g. for STAT, receive 9 integers describing the length of the
      9 \0-separated string lists to be read:
       * one file list for each lmar!?ic status type
       * one list containing the directories visited during lookup
