Big optimization of doAnyOutstandingRetransmits
...
Retransmitting does not change the set of incomplete hosts, so there's
no need to use a map to store the current position in the outstanding
probes queue. Using a vector is much faster. Additionally, improper use
of std::map::find() and std::map::operator[] meant that the O(logN)
lookup was happening 4 times for a single host for each iteration
through the loop. Complexity for N targets is now O(N), not O(N logN)

Combine tryno and pingseq
...
UltraProbe's tryno and pingseq attributes were mutually exclusive,
encoded in the same places in packets, and did not need more than 7 bits
to store. This change combines them into a bitfield. This simplifies
some logic, since they do not need to be distinguished from each other.
Additionally, in cases where the tryno is encoded in the source port
number, no further checks or decoding need to happen beyond comparing
the destination port of the response to the source port of the probe.

Fix #2293 : assertion failed probe->tryno == maxtries
...
When tying UDP payloads to tryno, we were exceeding the maxtries in
order to send all available payloads, leading to assertion failures.
Currently there are not more than 4 payloads for any given port; most
have none, many have 1, very few have more. So we will send them all at
the same time with the same source port/tryno.
