Stefan Reinauer has submitted this change. ( https://review.coreboot.org/c/em100/+/47842 )

Change subject: Rename do_exit_flag to exit_requested
......................................................................

Rename do_exit_flag to exit_requested

... and change the type to sig_atomic_t. Also, make it
globally available again (because it is indeed useful in
other parts of the code)
