Deal with ref after free found by ASAN when a function redefines
itself, or some other function which is still active.
This was a long known bug (fixed ages ago in the FreeBSD sh) which
hadn't been fixed as in practice, the situation that causes the
problem simply doesn't arise .. ASAN found it in the sh dotcmd
tests which do have this odd "feature" in the way they are written
(but where it never caused a problem, as the tests are so simple
that no mem is ever allocated between when the old version of the
function was deleted, and when it finished executing, so its code
all remained intact, despite having been freed.)
The fix is taken from the FreeBSD sh.
XXX -- pullup-8 (after a while to ensure no other problems arise).

christos | Fixes from David Laight:
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
(so I could unset -e PS1 before running the test shell...)

christos | Rename ALIGN to SHELL_ALIGN and simplify macro so that it does not have side
effects, and add double to it, so that it aligns doubles correctly too. This
is just a workaround to fix the sparc64 problem where ALIGN() is now defined
in some include file to be 16 instead of 8. Thanks to martin for debugging this.
