io/pointer: re-introduce PassOp

Browse Source 
A previous change merged PassOp with AreaOp under the assumption that
the pass mode would be set on a particular area. That assumption turns
out not to hold, so this change brings back PassOp as an independent
stack operation.

This is an API change: replace AreaOp{Pass: true} with a separate
pointer.PassOp operation.

Fixes gio#288
