Handling of ngx_int_t != intptr_t case. Casts between pointers and integers produce warnings on size mismatch. To silence them, cast to (u)intptr_t should be used. Prevoiusly, casts to ngx_(u)int_t were used in some cases, and several ngx_int_t expressions had no casts. As of now it's mostly style as ngx_int_t is defined as intptr_t.
