Allow multiple hostnames/addresses separated by comma to be specified
with the -h option. Hostnames are resolved to up to 16 addresses. When
connecting to an address fails or no reply is received, try the next
address in the list.
Set the default value for the -h option to 127.0.0.1,::1.
This is to make sure chronyd will see the remote address as 127.0.0.1
and allow access even when localhost resolves to an address of a
non-loopback interface.
