Class WasmScopeAbi

Language-neutral AngularTS scope ABI for raw Wasm clients.

The ABI exchanges strings and JSON-compatible values through guest linear memory. Guest modules provide ng_abi_alloc and ng_abi_free; AngularTS uses those exports whenever it needs to place callback or return payloads in guest memory.
