Some errors have exit status values specified by POSIX and it is
therefore desirable to be able to set the exit status at the EXERROR
source rather than in main.c.

Now that eval handles EV_TESTED correctly, we can remove the
SKIPEVAL hack and simply use EXEXIT for set -e.

This change updates the BSD licence to the three-clause version since
NetBSD has already done so. This makes dash GPL-compatible.
It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file.
I've added "copyright by Herbert Xu" to most files.
Finally all CVS IDs and inclusion of sys/cdefs.h have been removed.
The latter is needed for support of klibc.

Let evaltree handle traps from cmdloop.
Reset evalskip after minusc is executed.
Stop executing traps once SKIPEVAL is seen.
