Jilles Tjoelker eb33e843b8 sh: Fix crash when undefining or redefining a currently executing function.
Add a reference count to function definitions.
Memory may leak if multiple SIGINTs arrive in interactive mode,
this will be fixed later by changing SIGINT handling.

$FreeBSD$

This directory tree contains tools used for the maintenance and
testing of FreeBSD.  There is no toplevel Makefile structure since
these tools are not meant to be built as part of the standard system,
though there may be individual Makefiles in some of the subdirs.

Please read the README files in the subdirs for further information.
