The integer signals whether there is actually a caller or not. It will be 1 if there is a caller, 0 if no caller, and the contract is the first in the call chain. This allows for contracts to more easily handle the situation in which they're the first to be called, a situation which happens often downstream in e.g. queries.

We remove the concept of a
ContractIdbeing "uninitialized" and all related functionality, and in its place put in an improved ABI, using an integer to signal whether there is a caller or not. These two concepts are semantically equivalent, with the exception that in the former the contract at "zero"ContractIdis not a possible caller - instead being considered "uninitialized".As a consequence, we can return
Option<ContractId>frompiecrust_uplink::caller, which is a much clearer and more ergonomic API.
