isisd: fix crash on "no router isis" (BZ#536)
The crash is due to threads accessing data that gets destroyed during the removal of the configuration. * isis_circuit.c: Destroy adjacencies to stop adjacency expiry thread. Stop PSNP threads. * isisd.c: Change state of circuit back to INIT and reassign the circuit structure to isis->init_circ_list rather than destroying the circuit data structure. Stop SPF threads. Stop LSP generation threads. * isisd.h: Add pointers to LSP threads into area structure in order to stop them in isisd.c * isis_lsp.c: Store pointer to LSP thread in area structure. * isis_pdu.c: Stop PDU generation for a circuit with a removed area. * isis_pfpacket.c: Stop processing received PDUs for a circuit with a removed area.
