Change class inchash to move into a inchash namespace as requested.
The class is now inchash::hash
Rename iterative_hstate_expr to inchash::add_expr
... and convert existing users. It wasn't possible to use hash::,
because that lead to name space conflicts with cp and objc.
So class inchash is now inchash::hash and iterative_hstate_expr
