- Changed apistatusd.conf: set server.host default value to 0.0.0.0 to
improve error messages; needs checking if this disabled ipv6
- Changed apistatusd.conf: renamed default client.cert filename to
improve meaning
- Fix create_ssl_context: context.options was reset by misuse of `=`
instead of binary or assignment `|=`
- Changed main/socket-creation: disabled keepalive
- Fix main/connection/pre-ssl-handshake: set missing tls handshake
timeout; code went into infinite waiting block
- Some cleanup
