Add APIs for t(ree) alloc(ated) memory management.
These APIs allocate memory like malloc, but track those allocations via
a parent-child relationship, or tree. If the parent is freed while it
still has children, a panic will be triggered. This effectively gives
you the ability to limit the lifetime of an allocation by ensuring the
child allocation lifetime will be strictly less than the parent
allocation lifetime.
