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 Change-Id: I61d3056251b87076be0578ccda300aa311c222ef Signed-off-by: Damjan Marion <damarion@cisco.com>
