- csplit didn't clean up if two signals arrived nearly simultaneously.
(sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]: Define.
(filename_space, prefix, suffix, digits, files_created, remove_files): Now volatile.
(caught_signals): New var.
(cleanup): Block signals while deleting all files.
(cleanup_fatal, handle_line_error, regexp_error):
Mark with ATTRIBUTE_NORETURN.
(create_output_file, close_output_file, interrupt_handler):
Block signals while changing the number of output files,
to fix some race conditions.
(delete_all_files): Do nothing if remove_files is zero.
Clear files_created.
(main): Don't mess with signals until after argument processing is done.
(main): Rewrite signal-catching code to make it
similar to other coreutils programs. When processing signals,
block all signals that we catch, but do not block signals that we
don't catch. Avoid problems with unsigned int warnings.
(interrupt_handler): Use void, not (obsolete) RETSIGTYPE.
(interrupt_handler) [defined SA_NOCLDSTOP]:
Use simpler "signal (sig, SIG_DFL)" rather than sigaction equivalent.

(sighandler) [defined SA_NOCLDSTOP]:
Use simpler "signal (sig, SIG_DFL)" rather than sigaction equivalent.
(sighandler) [!defined SA_NOCLDSTOP]: Reset signal
handler to self, not to SIG_IGN, since SIGTSTP can be received more than once.
(main): Use SA_RESTART, as that is simpler than checking for EINTR
failures all over the place.
Include <signal.h>.
(main) [defined SIGCHLD]: Set SIGCHLD handler to the default,
if -s is given, since System V fork+wait does not work if SIGCHLD
is ignored.

(first_call): Make it private to rpl_nanosleep, and have it
be zero initially as that's a bit faster.
(my_usleep): Round up fractional times instead of truncating them,
as this is the usual meaning for 'sleep'.
can override the one in --version output. This is needed solely
so that test.1 doesn't refer to `[' as the program name.
