Joe Tsai 56076c3080 io: reduce allocations in Pipe constructor
Rather than having PipeWriter and PipeReader a wrapper type on pipe,
make them have the same underlying memory representation and
rely instead of simply casting the same *pipe pointer
as either a *PipeReader or *PipeWriter to control the set of methods.

This reduces the number of allocations by 2,
going from a total of 6 down to 4 allocations.
