zebra: deal with irdp compile warnings
* zebra/irdp.h
* irdp_send_thread(): move prototype to common header file
* irdp_advert_off(): idem
* process_solicit(): idem
* irdp_read_raw(): idem
* send_packet(): idem
* zebra/irdp_interface.c

* in_cksum(): lib/checksum.h already provides prototype
* irdp_send_thread(): prototype moved away
* inet_2a(): idem
* irdp_advert_off(): idem
* b1, b2, b3, b4: get rid of global buffers for inet_2a()
* if_group(): add local buffer for inet_2a()
* if_add_group(): idem
* if_drop_group(): idem
* irdp_config_write(): idem
* Adv_new(): make static
* zebra/irdp_main.c
