which fills in a caller-supplied buffer.
Create "_buf()" versions of various "to_str" routines for various
address types, and create a routine to map SNA FIDs to strings, and use
them to finish up "address_to_str_buf()".
Get rid of the declaration of "sna_fid_type_4_addr_to_str()" in
"packet-sna.h", as that routine has been swallowed up in
"sna_fid_to_str()".
