    every second, and then they get time to complete during a reload,
    this is a process that lingers with the old version during a version
  - Fix #13: Stray dot at the end of some log entries, removes dot
    after updated serial number in log entry.
  - Fix TLS cipher selection, the previous was redundant, prefers
    CHACHA20-POLY1305 over AESGCM and was not as readable as it
    could be.

    create, with hardening for the remote control tls context too.

    by Mykhailo Danylenko.
  - Initialize event structures before event_set, to stop uninitialized
    values from setting event library lists and assertions, that would
    sometimes also show after event_del.
