bors 3c89031e1f auto merge of #18613 : steveklabnik/rust/ownership_guide, r=huonw
This is a work in progress, but this should get *extensive* review, so I'm putting it up early and often.

This is the start of a draft of the new 'ownership guide,' which explains ownership, borrowing, etc. I'm feeling better about this framing than last time's, but we'll see.
