Time remaining estimates are now based on a moving average work unit
completion rate instead of percent completion of the entire task. This
better fits tasks that may increase the number of work units as time
goes on (such as increasing the number of retries for any given probe)

Avoid passing empty string to nsock_pool_set_device
...
Nsock checks for NULL, but not for empty string. Rather than making
Nsock decide, each app will decide whether to call
nsock_pool_set_device, with all currently skipping the call if device is
an empty string.

mass_dns: only scale back for initial requests
...
Some requests just take longer; they may have lots of recursion or a
slow authoritative server. That won't change on retransmissions, so if
we treat all requests and retransmissions equally, we get a long tail of
retransmits with smaller and smaller capacity (parallelism). Instead, we
will use the initial-request period to determine server capacity and
then not change it during the retransmit phase.
