scamper:
* fix regression from 20250106 where scamper might not write the final
  measurement result and hang indefinitely, if you are unlucky.
* add do-not-probe file support, with -O dnp=file option, documented
  in man page.  do-not-probe file support can be disabled with
  --disable-scamper-dnp configure option.
* let traceroute with PMTUD use ICMP-echo probes, document in man page.
* document existence of ping -O mss=val option in man page.

throughout:
* remove string_concaf from more places.

Python module:
* no change to the module.
* in python interface file (scamper.pyi), fix types of
  ScamperDealiasMidardiscRound.start and ScamperCtrl.do_midarest(addrs),
  and make ScamperCtrl generic in parameter type to help with static
  type checking.

sc_remoted:
* catch TERM signal (in addition to INT and HUP)
* write pidfile after becoming daemon, when -D is used
