Since TypeScript 2.9.  We are already using noUnusedLocals in
tsconfig.json.

This better disambiguates with the msg_generated.ts module, which in JS
we call "fbs", but would be better called "msg".

Adds deno.listen(), deno.dial(), deno.Listener and deno.Conn.

This behavior was fixed by #885.

We need this specific version because ts-simple-ast depends on it. See
https://github.com/denoland/deno/pull/729#issuecomment-426352887

Renames:
deno.platform -> deno.platform.os
deno.arch -> deno.platform.arch

Removes unsupported operating systems and CPU architectures from the
types. Uses the string "win" instead of "win32".

These tests weren't running because with the old timer implementation
time-outs were sometimes lost, and the test harness uses setTimeout
to throw errors after a test has failed.

Fixes #878.

Closes #682.

The benchmark was added in b7fd6e but was not surfaced in the UI.

TODO: The tests should have failed and caught this situation.

Fixes #857

Use tokio_io::io::read() and tokio_io::io::write_all()
instead of poll_fn() as suggested in the Tokio gitter.

Add docs to src/resources.rs.

Fixes #872

Fixes #865.
