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()
