  -----------
  usrloc: Several fixes regarding contact IDs

    * always increment record.next_clabel modulo CLABEL_MASK
	(this is critical, because clabels are 14-bit wide, while an
	    unsigned short is 16-bit, so we'd overflow into the rlabel)
    * regen_broken_contactid: do not re-insert all contacts to DB if
            a single one is broken
    * do not update urecord contact labels on contact updates
	(the label may have rotated! by setting it to a high value,
	  we're almost encouraging a conflict once it rotates again)

(cherry picked from commit 93163b9eb84df8edad1a0b1ea283d8d13042aab0)
