This patch replaces the cmdenviron mechanism for temporary command
variables with the localvars mechanism used by functions.
This reduces code size, and more importantly, makes the variable
assignment take effect immediately as required by POSIX.

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

Removed obsolete extern declaration on funcnest. This conflits with the
correct static definition.
Changed memtodest prototype to use char * instead of unsigned char *.
Perform the unsigned char cast inside memtodest 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.

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

This allows SKIPEVAL and SKIPFUNC to coexist which is needed for eval return 1.
