padvance_magic() returns -1 when there are no more paths left, not
zero.

This fixes "you have mail" showing right after checking and deleting
mail, resulting in a modified but empty mailbox. Also somehow fixes
"you have mail" always showing 3(!) times.

This patch changes the parsing of pathopt. First of all only
%builtin and %func (with arbitrary suffixes) will be recognised.
Any other pathopt will be treated as a normal directory.
Furthermore, pathopt can now be specified before the directory,
rather than after it. In fact, a future version may remove support
for pathopt suffixes.
Wherever the pathopt is placed, an optional % may be placed after
it to terminate the pathopt.
This is so that it is less likely that a genuine directory containing
a % sign is parsed as a pathopt.
Users of padvance outside of exec.c have also been modified:
1) cd(1) will always treat % characters as part of the path.
2) chkmail will continue to accept arbitrary pathopt.
3) find_dot_file will ignore the %builtin pathopt instead of trying
to do a stat in the accompanying directory (which is usually the
current directory).
The patch also removes the clearcmdentry optimisation where we
attempt to only partially flush the table where possible.

Many callers of padvance immediately free the allocated string
so this patch moves the stalloc call to the caller. Instead of
returning the allocated string, padvance now returns the length
to allocate (this may be longer than the actual string length,
even including the NUL). For the case where we would previously
return NULL, we now return -1.

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.
