Add rights for get/set options. Update message pipe and data pipe APIs.

Rationale for having separate get/set options rights: Otherwise, you can
control the abilities to read from a data pipe consumer and set its
options independently, but the abilities to write to a data pipe
producer and set its options are tied to a single right.

Still to do separately: I still have to update docs for other APIs.
Also, I can't really test these in a reasonable way until I've
implemented MojoGetRights() and MojoReduceRights().
