### BREAKING CHANGES
* **reactivity:** Reactivity APIs adjustments:
-`readonly` is now non-tracking if called on plain objects.
`lock` and `unlock` have been removed. A `readonly` proxy can no
longer be directly mutated. However, it can still wrap an already
reactive object and track changes to the source reactive object.
-`isReactive` now only returns true for proxies created by `reactive`,
or a `readonly` proxy that wraps a `reactive` proxy.
- A new utility `isProxy` is introduced, which returns true for both
* **compiler-core:** should not generate CLASS/STYLE patch flags on components ([a6e2b10](https://github.com/vuejs/vue-next/commit/a6e2b1052a4d461767147a6c13854fcb4f9509d2)), closes [#677](https://github.com/vuejs/vue-next/issues/677)

### Code Refactoring

### BREAKING CHANGES
* **reactivity:** `markReadonly` has been removed.
* **runtime-dom:** Only props starting with `on` followed by an uppercase
letter or a non-letter character are considered event listeners.
* **runtime-core:** this.$emit() and setupContext.emit() no longer
return values. For logic that relies on return value of listeners,
the listener should be declared as an `onXXX` prop and be called
directly. This still allows the parent component to pass in
a handler using `v-on`, since `v-on:foo` internally compiles
* **compiler:** should not condense ` ` ([8c17535](https://github.com/vuejs/vue-next/commit/8c17535a470501f7f4ec3747cd3de25d9169c505)), closes [#945](https://github.com/vuejs/vue-next/issues/945)
