- update to version 20230605:
  * HEADSUP: if you previously used -e pidfile to record the pid of a
  running scamper process, there is a good chance that the pidfile is
  owned by root.  scamper now attempts to write this file using the uid
  that started scamper, and will not be able to write it if scamper is
  not started by root (it should not be, rather the scamper binary
  should be setuid root).  Please delete the existing pidfile, or change
  its ownership, prior to restarting scamper, or scamper will not start.
  * scamper:
  * 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:
  * 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.
  * 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.

  * add -O skipnameverification option to tell sc_remoted to verify
    scamper presents a certificate signed by the CA, but do not do
    name verification

- Drop libscamperfile1 provides from the lib subpckage:
  libscamperfile.so.2 is not a drop-in replacement for anything
  that linked libscamperfile.so.1, and as such the provides is
  invalid. The obsoletes is technically wrong, but is there to fix
  the upgrade path of a wrongly-packaged libscamperfile.so.2 in a
  libscamperfile1 package.

  * scamper:
  * json output format for tracelb (MDA traceroute)
  * print an error message if an output file cannot be opened
  * document (in warts.5) the offset variable in a warts traceroute record,
    and scamper_trace_dtree_t

  * don't crash on a zero length file, or other conditions where sf->type
    is SCAMPER_FILE_NONE
  sc_ally:

    probing on with -I and there is a list of low-priority probing
    that is not empty, so that sc_uptime can meet the probe interval.
  * add the ability to expire addresses out of the database after they
    have not been seen in traceroute for a while, and they do not
    respond with an incrementing IPID value, with optional -E expiry
    parameter.
  * loading addresses into the state database is now a separate step (-a)
  * add a -c option to create and initialise a database file
  * add do-not-probe support
  * replace import code that used a row for each sample with a blob that
    stores multiple samples per blob.

  * build monotonic sequences which allow patterns in responses to be
    more easily identified, so that reboots are not falsely inferred
    in the cases of multiple counters, 16 bit counters, and routers
    that start each sequence after a PTB with a new IPID.
  * add an -O verbose to dump IPID sequences
  * document updates in sc_uptime.1

  * add cycle-start and cycle-stop json record implementations.
  * fix traceroute json record: the hop transmit time value it reported
    was junk.

  * quality assurance on research paper cites in manual pages.
  * spelling errors noticed by Iain R. Learmonth.
  sc_ally:
  * add feature to dump inferred aliases from the collected data.

  - -disable-threads configure option is not supplied.
  sc_uptime:
  * new scamper driver to infer IPv6 device reboot windows if the device
    returns an incrementing identifier field in the IPv6 fragmentation
    header.  the driver is not built by default, as it expects sqlite3.
    use --with-sc_uptime configure option to build.

- update to 20161204a
  * More fixes to libscamperfile caught with fuzz testing.  corrupt
  warts files provided by Greg Ward of Dyn
  * if targets or commands are specified in a file, and that file
  ends after all probing of commands in that file has completed,
  finish the source, allowing scamper to exit.  this scenario is
  most likely when stdin is the input file.  Reported by Alex
  Colvin of Dyn
  * use select/poll/epoll/kqueue to look for read events on stdin files
  * malloc enough memory for a prefix6_t in the prefixtree code.  reported
  by Sebastian Wagner via gcc7.  only sc_bdrmap uses that code
  * increase size of string buffers for some ping and trace fields for text
  output to silence gcc7 warning.
  * allow source IP address to be null when outputting a trace with json
  * update sc_tbitblind.1 man page to show correct use of scamper's IPFW
  firewall support, which changed in the 20161204 release
  * fix unlikely unaligned access when computing checksums with IPv6
  addresses

- update to 20161204
  * add remote control socket support to scamper.  scamper can be
  configured to connect to a remote controller at run time to
  allow remote systems to control a scamper instance.  the
  remote controller is handled by the sc_remoted utility, and
  is documented in the sc_remoted manual page (see below).
  * fixes to libscamperfile caught with fuzz testing.  corrupt
  warts data files provided by Greg Ward of Dyn.
  * add a PATRICIA trie implementation based off Sedgewick's
  Algorithms in C++ book.  this improves the performance
  of scamper compared to holding addresses in splaytrees.
  * improve speed of warts(5) code.
  * improve speed of scamper_writebuf by allocating pagesize blocks
  at a time.
  * begin to document ping warts records in warts(5).
  * fix debug printf implementation so that all features will
  be built in as long as --without-debugfile is not used.
  backported to 20141211g.
  * silence compiler warnings from Microsoft Visual Studio.
  backported to 20141211g.
  * sc_prefixscan:
  * add a utility, sc_prefixscan, that provides a convenient
    interface to scamper's prefixscan alias resolution method.
    https://www.caida.org/tools/measurement/scamper/man/sc_prefixscan.1.pdf
  * sc_radargun:
  * add a utility, sc_radargun, that provides a convenient
    interface to scamper's radargun implementation.
    https://www.caida.org/tools/measurement/scamper/man/sc_radargun.1.pdf
  * sc_remoted:
  * add a utility, sc_remoted, that provides an interface to a
    collection of remote scamper instances.
    https://www.caida.org/tools/measurement/scamper/man/sc_remoted.1.pdf
  * sc_ally:
  * use writebufs so sc_ally is event driven and will not block.
  * add code to probe candidate sets in pairs, with transitive
    closure to save probes.
  * allow inter-probe gaps of less than 1 second.
  * sc_attach:
  * add support for remote control sockets.
  * add an option to randomise the order tasks are run.
  * sc_speedtrap:
