[#15,!10] Minor changes to eliminate warnings under GCC 9

added release note

common/parse.c
    parse_warn() - upped format buffer size to squelch warning

includes/dhcpd.h
    struct interface_info - bumped name size by 1 to squelch warning

relay/dhcrelay.c
    request_v4_interface() - replace strncpy with memcpy to
    squelch warning (len is already checked above it)

server/confpars.c
    parse_failover_peer() - pass token value into log_fatal
    calls rather than null pointer
