Previously reset was called after exitshell. This was changed
so that it was called before exitshell because certain state needed
to be reset in order for the EXIT trap to work.
However, this caused issues because certain other states (such
as local variables) should not be reset. This patch fixes this
by creating a new function exitreset that is called prior to
exitshell and moving reset back to its original location.

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.
