* scamper:
* handle many ports in BPF compiler better.
* remove cycles, autoreload features from file input sources.
* do not compile in support for select(2) by default (saving CPU and
memory in the default use).
* normalize kqueue(2) / epoll(2) code paths.
* use IP_RECVIF on platforms (FreeBSD) that don't have IP_PKTINFO.
* remove sig_tx_ip_src from task signature structure, nothing used it.
* add holdtime (-H) parameter back to scamper, will controls the
length of time that scamper will hold task signatures before
allowing a follow up measurement to use the same signature. 5
seconds by default, disable with zero (to save memory and CPU).
* fix compilation when platform has IPV6_PKTINFO but not
IPV6_RECVPKTINFO setsockopt (old platforms).
* replace calls to getaddrinfo AI_NUMERICHOST with calls to inet_pton
(fixes complilation on old MacOS, and is probably the faster
solution generally).
* increase pps-max (scamper -p) to 50,000.
* adjust timestamps using datalink timestamps when using
trace -N <squeries>.
* reduce memory use in storing traceroute state.
* remove per-measurement pktbufs, to save a tiny amount of memory.
* refactor BPF compiler to make it more obvious what is going on.
* refactor ping task signatures to make it more obvious what is going
on.
* refactor scamper's timeout calculation to make it more obvious what
is going on.
* move output of done tasks into its own function to make it more
obvious what is going on.
