Runtime calls

Calls are categorized according to the dispatch origin they require:

1. User calls: the dispatch origin for this kind of call must be signed by the transactor. This is the only call category that can be submitted with an extrinsic.
2. Root calls: This kind of call requires a special origin that can only be invoked through on-chain governance mechanisms.
3. Inherent calls: This kind of call is invoked by the author of the block itself (usually automatically by the node).
4. Disabled calls: These calls can not be called directly, they are reserved for internal use by other runtime calls.
