merged changelog is as follows:

scamper:
* use a random source port / ICMP ID in trace if -s 0.
* better parallelize pings to a single destination that use
  udp-dport, tcp-ack-sport, or tcp-syn-sport probe methods.
* document default value of source port consistently for all
  measurements that take a source port parameter in the man page.
* write a process ID that the user that started scamper can kill
  in the pidfile when using privsep.
* when using privsep, exit the unprivileged process if the privileged
  process exits (is killed)
* run as real uid from the start of scamper, for both privsep and
  not-privsep.
* fix bug where attempting to open an unsupported datalink would
  leave a freed scamper_fd_t in the fd_tree and fd_list, leading to
  a crash.
* fix double free triggered when a user provides an invalid dealias
  command.
* fix memory leak if the payload was specified twice to ping or trace
* rework pollfunc selection logic, use kqueue/epoll by default.
* remove _malloc_options = "AJ" as this only works on unsupported
  versions of FreeBSD.
* add additional paramaters to attach command to allow the user
  to override list and cycle parameters, documented in manual page.
* catch EAGAIN/EINTR from select/kqueue/epoll to allow gdb to attach
  and detach without flagging errors.
* for DNS replies for host command, record reply flags and rcode.
* add support for SOA and NS queries in host.
* add a JSON output for host measurements.
* do not let scamper emit warts to a tty.  check for isatty in
  configure.
* only allow -O and -z to be specified multiple times in a trace command
* only allow -O to be specified multiple times in a ping command
* split command parsing logic out from task probing logic.  add
  fuzzing cradle for parsing logic for all measurement types, and
  basic unit tests for dealias, ping, and trace parsing logic.
* autodetect output type by file extension if output type is not
  explicitly specified on the command line.

libscamperfile:
* add ability for scamper and all utilities to read warts and arts
  files compressed with bzip2 and xz, if libbz2 and liblzma are found
  by configure.
* add ability for scamper and all utilities to write warts files
  compressed with gzip, bzip2, and xz, if zlib, libbz2, and liblzma
  are found by configure.
* remove all struct definitions from libscamperfile (e.g.
  scamper_trace, scamper_ping, scamper_addr, etc).  provide typedefs
  for each (scamper_trace_t) and _get() functions that return the
  field requested.  This change will allow hopefully allow
  libscamperfile's version to stabilize.  all scamper utilities now
  use these get functions.
* shift some functions that were previously implemented in
  libscamperfile into the one place they were used, if they were only
  used in (for example scamper / sc_analysis_dump / other scamper
  utility).  delete other functions that were not used anywhere in
  the public scamper release.
* tidy up libscamperfile code.

libscamperctrl:
* fix bug by ensuring line_off is always valid after the read.
* catch EAGAIN from select.
* add kqueue support.
* add scamper_attp_* routines to allow applications to specify
  list and cycle parameters.
* for scamper_inst_do, take a parameter to keep with each task.
* add scamper_task_getparam function to get the parameter.
* add scamper_task_getcmd function to get the command associated with a task.
* use TYPE_FATAL instead of TYPE_ERR in application callback when
  scamper_inst_read encounters a fatal error, only use TYPE_ERR when
  scamper does not accept a command.

sc_prefixprober:
* new driver to conduct measurements (ping, trace, tracelb) to an
  address in each prefix.

sc_ally:
* use scamper_file_t outfiles, add ability to write gz/bz2/xz files.
* ask for cycle-start and cycle-stop records, write them out.
* improve use of libscamperctrl.

sc_hoiho:
* add support for VP geohints, document.
* silence -Wshadow.
* silence warnings related to assignments that are not used.

sc_ipiddump:
* fix memory leak when user specifies invalid command line options.

sc_filterpolicy:
* ask for cycle-start and cycle-stop records, write them out.
* improve use of libscamperctrl.

sc_pinger:
* signal done to get cycle stop record.
* improve use of libscamperctrl.
* document remote socket option.

sc_prefixscan:
* use scamper_file_t outfiles, add ability to write gz/bz2/xz files.
* ask for cycle-start and cycle-stop records, write them out.
* improve use of libscamperctrl.

sc_remoted:
* catch EAGAIN from select.

sc_speedtrap:
* ask for cycle-start and cycle-stop records, write them out.
* improve use of libscamperctrl.

sc_uptime:
* silence -Wshadow.
* silence warnings related to assignments that are not used.
* fix memory leak in up_reboots_doone.

sc_warts2json:
* fix memory leak with cycle start/stop records.
* emit json for host records.

sc_wartscat:
* print useful error messages when encountering an error.
* add ability to merge neighbourdisc, tbit, sting, sniff, and host.
* fix ability to write compressed warts files.

misc:
* silence -Wsign-compare and -Wtype-limits
* tidy usage statements for sc_uptime and sc_tbitpmtud
* document use of '-' to read from stdin and write to stdout
  in sc_wartsfilter.1
