Exit with a nonzero status if we get killed by a SIGINT. POSIX.2
specifies exiting with a zero status if the file was copied
successfully, and with a nonzero status if an error occurred. We
are too sloppy to tell if the file was copied successfully when we
get killed by a SIGINT, but it is unlikely to have been. Added a
comment about related sloppiness (calling exit() from a signal
handler).

Boy, I'm glad we're not using sup anymore. This update would have been

Increase precision of duration to microseconds.
No heuristics to avoid overflow in calculation needed - just depend
on DBL_MAX being a bit larger than LONG_MAX.

Use double instead of `struct timeval' in dd.h so that everything
doesn't have to include <sys/time.h>.

Fixed style bugs in recent and old FreeBSD changes.

Previous commit broke dd(1)'s I/O summary when it's terminated by a
signal. Fix it by adding an explicit call to summary() in terminate()
(it was previously called implicitly by exit() because summary() was
registered with atexit()). summary() is supposed to be signal-safe--
it handles SIGINFO almost exclusively--so this should be safe.
