vlib: stack trace and signal handler improvements

 - use libunwrap which seems to be industry standard
 - display traceback on console if running interactive or with syslog
   disabled (color output unless nocolor specified)
 - print hexdump of offending code
 - print library filename for each stack frame

Type: improvement
