This commit is the next step in integrating `wasm32-wasi`, `wit-bindgen`, tests, and components all together. Tests are now again compiled with `wasm32-wasi` and use a repo-specific adapter module (with support from bytecodealliance#338) to support transforming the final module into an actual component. In supporting this feature the support from bytecodealliance#331 is refactored into a new `extract` Rust module so the functionality can be shared between the ingestion of the main module as well as ingestion of adapter modules. Adapter modules now are also supported on the CLI as a standalone file without having to specify other options. Note that the actual `wasi_snapshot_preview1.wasm` adapter is non-functional in this commit and doesn't do anything fancy. The tests in this repository don't really need all that much and I suspect all we'll really need to implement is `fd_write` for fd 1 (as that's stdout).

In the interest of decoupling I'll work on that in parallel, github actions is having a fit right now and not actually running so it'll take a bit to land the wasmparser changes and for now the custom sections are otherwise harmless. |
