start migrating handles to fat pointers
CI will fail from this commit onward. Currently working: $ bootstrap translate init.linux 0[4-7]*.subx 080zero-out.subx -o a.elf && ./a.elf test $ bootstrap run a.elf test $ chmod +x a.elf; ./a.elf test Plan: migrate functions that used to return handles to pass in a new arg of type (addr handle). That's a bit of a weird type. There should be few of these functions. (Open question: do we even want to expose this type in the Mu language?) Functions that just need to read from heap without modifying the handle will receive `(addr T)` or `(handle T)` types as arguments. As I sanitize each new file, I need to update signatures for any new functions and add them to a list. I also need to update calls to any functions on the list.
