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
* use autoconf to check if X509_VERIFY_PARAM_set1_host is available,
  rather than OpenSSL #defines that are not used consistently among
  OpenSSL-like libraries.

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

sc_ally:
* fix example in manual page
* dump 3: when merging routers in a transitive closure, remove the
  obsolete router from the dump list.
* if an address is repeated in the input file then complain

sc_bdrmap:
* document -C csum in sc_bdrmap.1
* allow duplicate prefixes in the IXP file
* add initial support for UDP paris traceroute, as an alternative
  to the ICMP paris traceroute bdrmap uses by default.
* document updates in sc_bdrmap.1

sc_ttlexp:
* add -O noreserved
* bugfix reading from stdin, file handling
* document updates in sc_ttlexp.1

sc_uptime:
* add an optional -I interval parameter which controls how frequently
  we want an address to be probed.  add logic to exit early if we are
  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.
* report some measure of progress on import
* 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
