Summary:
This diff
- creates `XHRInterceptor` to intercept all XMLHttpRequest network operations in React Native by monkey-patching.
- enables `XHRInterceptor` in RN development tool "inspector".
This interception and inspector tool work well on both Android and iOS. And this supports interception on any network API based on XMLHttpRequest, especially the Fetch API.
By now, we can intercept 12 information fields of a XMLHttpRequest including method, url, data sent, status, response type, response size, requestHeaders, responseHeaders, response, responseURL, responseType and timeout.
Follow-up:
- Will add UIs in the inspector on top of this diff, to display all the network operation information. (Not in this diff just to make this shorter)
- Will extend this to gather other valuable information towards one XMLHttpRequest.
- Should support other network request APIs like WebSocket.

Summary:Set `Touchable.TOUCH_TARGET_DEBUG` to see colored borders/text to all touchables.
Different touchable types are color-coded differently.
If there is `hitSlop`, it will be rendered with an extra view with a dashed border of the same color (not visible on
Android because `overflow: 'hidden'`).
`Text` with `onPress` directly set is just colored.
Added some extra checks to `TouchableWithoutFeedback` since it could silently break if the child is not a native
component.
Also added better error output for `ensureComponentIsNative` so it's easier to track down issues. I really wish there
was a cleaner way to get the component and owner names consistently, it would help make good debug messages way easier
to write.

Summary:
These are the changes needed for full interop with the (as yet unreleased) new
version of React Devtools.
- the on-device inspector is minimized when devtools is open
- devtools highlight -> device and device touch -> devtools select works
- editing react native styles :)
Summary:
The `InspectorOverlay` component was getting unwieldy, so I broke it into three components:
- Inspector
- InspectorOverlay
- InspectorPanel
and added @flow types.
The inspector was also living under the `ReactIOS` directory, and I moved it
up into the `Libraries` directory, as the inspector will soon be usable [on
Android](https://phabricator.fb.com/D2138319).
All features of the inspector should remain functional, with the addition of
one feature:
- you can toggle "touch to inspect" by tapping the "Inspect" button at the
bottom of the inspection panel. When inspection is disabled, the panel remains, but you can interact with
the app normally without touches being intercepted
@public
Test Plan:
Open the inspector:
- touch to inspect things, verify that margin, padding, size and position are
reported correctly, and that the component hierarchy is navigable.
- tap the "Inspect" button, and verify that you can interact with the app
normally.
