Table*, int -> Node*
Gets i-th node in table's hashpart array.
(Question: why isn't there a corresponding function
to get the i-th node in table's arraypart array? or why
have this macro at all?)
L0014    #define gkey(n)		(&(n)->i_key.nk)
Node* -> TValue*
Gets node key's TValue.
L0015    #define gval(n)		(&(n)->i_val)
Node* -> TValue*
Gets node value's TValue.
L0016    #define gnext(n)	((n)->i_key.nk.next)
Node* -> Node*
Gets node following given node in chain of nodes.
