Currently upon leaving a dotcmd the evalskip state is reset so
if a continue/break statement is used within a dot script it would
have no effect outside of the dot script.
This is inconsistent with other shells.
This patch is based on one by Jilles Tjoelker and only clears
SKIPFUNC when leaving a dot script. As a result continue/break
will remain in effect.
It also merges SKIPFUNC/SKIPFILE as they have no practical difference.

Instead of detecting EOF using the input layer, I'm going to
use the parser instead. In either case, we always have to read
ahead in order to complete the parsing of the previous node.
Therefore we always know whether there is more to come, except
in the case where we see a newline/semicolon or similar.
For the purposes of sh -c, this should be sufficient.

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.
