Depending on mode it may cancel all drive operations, wait for all drives
to become idle, exit(1). It may also prepare function
burn_drive_get_status() for waiting and performing exit(1).
If text is not NULL then it is used as prefix for pacifier messages of
burn_abort_pacifier().
If parameter handle may be NULL or a text that shall be used as prefix for
pacifier messages of burn_abort_pacifier(). Other than with an application
provided handler, the prefix char array does not have to be kept existing
until the eventual signal event.
Before version 0.7.8 only action 0 was available. I.e. the built-in handler
waited for the drives to become idle and then performed exit(1) directly.
But FreeBSD 8.0 sometimes pauses the other threads until the signal handler
