dpinger doesn't work with source IPs specifying a scope ID

Gateway Monitoring
Description
In the default DHCP6 WAN scenario where you're monitoring a link local gateway, the source IP passed to dpinger includes the scope ID. dpinger exits with "Invalid source IP address". It also fails and exits with "Invalid destination IP address" if the gateway IP includes the scope ID. That seems to get omitted from the monitor IP passed to dpinger in every circumstance, but should be permissible.
ping6 works with such source and destination addresses, such as:
ping6 -S fe80::250:56ff:feac:dd8c%vmx0 fe80::250:56ff:fea7:f865%vmx0
PING6(56=40+8+8 bytes) fe80::250:56ff:feac:dd8c%vmx0 --> fe80::250:56ff:fea7:f865%vmx0
16 bytes from fe80::250:56ff:fea7:f865%vmx0, icmp_seq=0 hlim=64 time=0.506 ms
I will add the ability to specify scope id as part of IP parameters.

dpinger runs now but the target also needs to be scoped, not just the source. Looking at the running dpinger command it does not appear to be using a scoped address for the target, and the gateway shows offline:
/usr/local/bin/dpinger -S -r 0 -i WAN_DHCP6 -B fe80::20d:b9ff:fe33:f71%re1 -p /var/run/dpinger_WAN_DHCP6_fe80::20d:b9ff:fe33:f71%re1_fe80::290:bff:fe37:a324.pid -u /var/run/dpinger_WAN_DHCP6_fe80::20d:b9ff:fe33:f71%re1_fe80::290:bff:fe37:a324.sock -C /etc/rc.gateway_alarm -s 250 -l 1000 -t 25000 -A 1000 -D 500 -L 20 fe80::290:bff:fe37:a324
If I kill that and start it with the target also scoped, it works:
/usr/local/bin/dpinger -S -r 0 -i WAN_DHCP6 -B fe80::20d:b9ff:fe33:f71%re1 -p /var/run/dpinger_WAN_DHCP6_fe80::20d:b9ff:fe33:f71%re1_fe80::290:bff:fe37:a324.pid -u /var/run/dpinger_WAN_DHCP6_fe80::20d:b9ff:fe33:f71%re1_fe80::290:bff:fe37:a324.sock -C /etc/rc.gateway_alarm -s 250 -l 1000 -t 25000 -A 1000 -D 500 -L 20 fe80::290:bff:fe37:a324%re1
