When we enter a subshell we need to drop the saved redirections
as otherwise a subsequent unwindredir could produce incorrect
results.
This patch does this by simply clearing redirlist. While we
could actually free the memory underneath for subshells it isn't
really worth the trouble for now.
In order to ensure that this is done in every place where we enter
a subshell, this patch adds a new mkinit hook called forkreset.
The calls closescript, clear_traps and reset_handler are also added
to the forkreset hook.
This fixes a bug where the first two functions weren't called
if we enter a subshell without forking.

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.
