   #   read_profile
   #
   #   Returns a set of specific entries from a user's profile file.
   #   this is a utility function that is used by both get_profile_entry and
   #   get_profile_entry_encrypted.
   #
   # Parameters:
   #    udom       - Domain in which the user exists.
   #    uname      - User's account name (loncapa account)
   #    namespace  - The profile namespace to open.
   #    what       - A set of & separated queries.
   # Returns:
   #    If all ok: - The string that needs to be shipped back to the user.
   #    If failure - A string that starts with error: followed by the failure
   #                 reason.. note that this probabyl gets shipped back to the
   #                 user as well.
