Message:

improve run-time termination

  • get rid of exit()
  • get rid of _exit(), use the common exit()
  • get rid of core(), use the common abort()
  • make main() more fail-safe (call abort() on unhealthy conditions), call async_sess_init() explicitly
  • add several libc-private headers for cleaner environment
  • use SYS_TASK_EXIT in exit() and abort()
