Refer to https://github.com/WebAssembly/WASI/blob/main/design/application-abi.md to check the WASI ABI compatibility: - Command (main module) may export _start function with signature "()" - Reactor (sub module) may export _initialize function with signature "()" - _start and _initialize can not be exported at the same time - Reactor cannot export _start function - Command and Reactor must export memory And - Rename module->is_wasi_module to module->import_wasi_api - Refactor wasm_loader_find_export() - Remove MULTI_MODULE related codes from mini_loader - Update multi-module samples - Fix a "use-after-free" issue. Since we reuse the memory instance of sub module, just to protect it from freeing an imported memory instance
