Review request for mesos and Joseph Wu.


Addressed Benjamin's feedback.

Summary (updated)

Avoided copying `Owned` pointers in the default executor.

Repository: mesos

Description (updated)

`Owned` pointers are copied in multiple places of the default executor.
This violates the semantic of owned pointers and works only because
`Owned` is currently implemented with `shared_ptr`, it would otherwise
lead to double-freeing the pointers.

This patch changes those places to use references to the original
`Owned` objects or raw pointers instead of copies.

Diffs (updated)
