This commit refactors the Wasmtime CLI tools to use `structopt` instead of `docopt`. The `wasmtime` tool now has the following subcommands: * `config new` - creates a new Wasmtime configuration file. * `run` - runs a WebAssembly module. * `wasm2obj` - translates a Wasm module to native object file. * `wast` - runs a test script file. If no subcommand is specified, the `run` subcommand is used. Thus, `wasmtime foo.wasm` should continue to function as expected. The `wasm2obj` and `wast` tools still exist, but delegate to the same implementation as the `wasmtime` subcommands. The standalone `wasm2obj` and `wast` tools may be removed in the future in favor of simply using `wasmtime`. Included in this commit is a breaking change to the default Wasmtime configuration file: it has been renamed from `wasmtime-cache-config.toml` to simply `config.toml`. The new name is less specific which will allow for additional (non-cache-related) settings in the future. There are some breaking changes to improve command line UX: * The `--cache-config` option has been renamed to `--config`. * The `--create-config-file` option has moved to the `config new` subcommand. As a result, the `wasm2obj` and `wast` tools cannot be used to create a new config file. * The short form of the `--optimize` option has changed from `-o` to `-O` for consistency. * The `wasm2obj` command takes the output object file as a required positional argument rather than the former required output *option* (e.g. `wasmtime wasm2obj foo.wasm foo.obj`).
