Major release with changes to naming and packet processing

Major changes

This version has additional self-healing code to recover if the system encounters a network error of if network packets are not being received. A monitoring goroutine will send a sigterm if IP packets are not received within a few minutes.

• api: new admin api to request logs
• api: new admin api to set log level
• packet: new processing of names via integrated mdns, llmnr, ssdp, nbns
• packet: auto detection of inactive network link and restart
• packet: save OS configuration if link errors encountered
• packet: experimental sleep proxy responder to attempt to identify Apple names earlier
• logging: use of fastlog - improve logging speed by 3-5 times with no memory allocation
• logging: force flush log to disk on exit and major errors to retain logs on reboot
• icmp6: more accurate options parsing
• nbns: integrated nbns processing without requiring external package
