Components that log each wasi:http call at the TRACE level, with the 'componentized-trace' context: * trace-types: wasi:http/types * trace-client: wasi:http/types and wasi:http/client * trace-handler: wasi:http/types and wasi:http/handler * trace: wasi:http/types, wasi:http/client and wasi:http/handler * trace-componentized-client: componentized:http/client Each component exports only the interfaces it traces, so it imports nothing more from the host than it needs. Traced client and handler calls take the traced request and response resources, so they can't be composed from trace-types with wac. Instead, the four wasi:http components compile the shared sources in crates/trace with cargo features that select the world. Resources are logged by the last four hex digits of their upstream handle, prefixed with `&`, e.g. `SELF=&002a`. Tests run each component in wasmtime with wasi:http from wasmtime-wasi-http. Requests sent upstream are recorded and answered with a canned response, without the network. Body streams passed through from the host can't be read by the harness, so the tests check status and headers.
