Subject: [PATCH] wasi: rename __wasi_unstable_reactor_start()

Upstream WASI has renamed __wasi_unstable_reactor_start() to
_initialize(). This commit updates Node's WASI implementation to
reflect that change.

 Attempt to begin execution of `instance` by invoking its `_start()` export.
 If `instance` does not contain a `_start()` export, then `start()` attempts to
-invoke the `__wasi_unstable_reactor_start()` export. If neither of those exports
-is present on `instance`, then `start()` does nothing.
+invoke the `_initialize()` export. If neither of those exports is present on
+`instance`, then `start()` does nothing.
 
 `start()` requires that `instance` exports a [`WebAssembly.Memory`][] named
 `memory`. If `instance` does not have a `memory` export an exception is thrown.
