unique_ptr and rvalue-reference updates from WP

I'm going to be offline until next week so here's what I have so far.
This adds the rvalue-references and unique_ptr changes from 20.7.12.2 in the
current WP, n2691, but I might have missed something.

While adding the new swap() overloads I realised we need to specialize swap()
for shared_ptr as well as __shared_ptr, because a user can detect the
difference by taking the address or explicitly specifying the template
parameters (the __shared_ptr overloads have an extra template param for the
lock policy.)

tested linux x86_64
