* Actually read CLI args in emscripten * Fix fetchfs manifest parsing, increase download chunk size The chunk size should probably be made a parameter in the future. The larger chunk size trades longer hitches for fewer hitches. * Add exec command driver and API functions for emscripten. Under WASMFS, stdin/stdout can't be customized the way they can with the JS FS implementation. Also, this approach frees up stdin/stdout and simplifies interaction with the command interface for web embedders. * fixup upload paths, show use of new emscripten cmd interface * Add JS library function names to EXPORTS as well as EXPORTED_FUNCTIONS for older emsdk versions
