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 waitcmd no longer uses EXSIG we can remove it.

As it stands if we get an error before procargs gets called by main()
we'll try to print out a null pointer. This patch avoids this by
printing out "sh" instead.

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.
