ash: exec: Stricter pathopt parsing

exec: Stricter pathopt parsing
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.
