* generic/tclDictObj.c: Changed the underlying implementation of the
hash table used in dictionaries to additionally keep all entries in
the hash table in a linked list, which is only ever added to at the
end. This makes iteration over all entries in the dictionary in
key insertion order a trivial operation, and so cleans up a great deal
of complexity relating to dictionary representation and stability of
iteration order.
