Nathaniel Wesley Filardo 5bb556cb68 Convert alloc paths to capptr::Alloc<void> ...

The use of void* had let an overzealous unsafe_ptr() leak a pointer with address
space control to the client (in LocalAllocator::alloc_not_small, specifically).
Correct this to call capptr_chunk_is_alloc() (to capture our intent) and
capptr_to_user_address_control() (to do the bounding) and defer the conversion
to void* until the very periphery of the allocator, using capptr_reveal()
(again, to capture intent).
