ims_registrar_scscf: 200OK changes according to RFC3261
Added corrections for 200OK reply on Re-Registration according to RFC3261 - registrar respond with multiple bindings in case of multiple bindings. Added a new parameter skip_multiple_bindings_on_reg_resp for 200OK reply used for Re-Registration. Default value is 0. If set to 1 - registrar replies only with current contact, not with multiple bindings.
