Original change's description:
> [zircon][sampler] De Alloc Buffers Between Sessions
>
> This patch allows us to safely deallocate the buffers once there are no
> longer any references to them. We achieve this by reference counting the
> buffers, ensuring that we only give out references while the session is
> running, then waiting for all references to be returned before
> deallocating the buffers.
>
> Test:
>
> fx run-boot-test  core-tests --test-filter 'ThreadSampler.*'
> fx run-boot-test  kernel-unittests-boot-test --kernel-unittest thread_sampler --symbolize
> fx test profiler
>
