Summary:We found that moving the preloaded modules to the startup section of the RAM Bundle improves TTI quite a bit by saving lots of through the bridge calls and injecting multiple modules at once on JSC. However, doing this on a non hacky way required a lot of work. The main changes this diff does are:
- Add to `BundleBase` additional bundling options. This options are fetched based on the entry file we're building by invoking a module that exports a function (`getBundleOptionsModulePath`).
- Implement `BundleOptions` module to include the `numPreloadedModules` attribute as a bundle additional option. This value is computed by getting the dependencies the entry file has and looking for the first module that exports a module we don't want to preload. The `numPreloadedModules` attribute is then used to decide where to splice the array of modules.
- Additional kung fu to make sure sourcemaps work for both preloaded and non preloaded modules.

Summary:Changing app state back to 'background' for UIApplicationWillEnterForegroundNotification.
On iOS we use the 'background' app state to determine whether a notification was tapped to foreground the app vs. received while app was already active. The PR https://github.com/facebook/react-native/pull/6379 changed RCTAppState so that it returned 'active' when app was being foregrounded from a notification; this changes it back to 'background' so that we can distinguish between the two cases again

Summary: For RAM bundling we don't want to hold the entire bundle in memory as that approach doesn't scale. Instead we want to seek and read individual sections as they're required. This rev does that by detecting the type of bundle we're dealing with by reading the first 4 bytes of it. If we're dealing with a RAM Bundle we bail loading.

Summary:Because the source of truth for backgroundColor is the shadow view, it's possible for the default RCTView backgroundColor to get overwritten by the current shadowView backgroundColor when the view is first created. This overridden value will then be used as the default whenever the background color is reset, which may not be be appropriate for other components that use RCTView.
This diff fixes the bug by ensuring that the view props (and therefore the default color) are set *before* the background color is propagated from the shadowView.

Summary:In order to ensure that the docked sticky header in a ListView receives touches correctly, RCTScrollView has a custom hitTest implementation that checks the sticky headers for touches prior to checking any other views.
There was a bug in this implementation that meant that sticky views would get touch priority even if the touch was outside the bounds of the scrollView. This meant that sticky headers that scrolled off the top of the list would intercept touches intended for views placed above the scrollView.
This diff fixes that bug by checking that the touch is inside the scrollview before checking for sticky header touches. I've also limited the custom hit test logic to just the currently docked header, as the other sticky header views do not require special treatment.

Summary:This rev adds support for production sourcemaps on RAM.
When we inject a module into JSC we use the original `sourceURL` and specify the `startingLineNumber` of the module relative to a "regular" bundle. By doing so, when an error is thrown, JSC will include the provided `sourceURL` as the filename and will use the indicated `startingLineNumber` to figure out on which line the error actually occurred.
To make things a bit simpler and avoid having to deal with columns, we tweak the generated bundle so that each module starts on a new line. Since we cannot assure that each module's code will be on a single line as the minifier might break it on multiple (UglifyJS does so due to a bug on old versions of Chrome), we include on the index the line number that should be used when invoking `JSEvaluateScript`. Since the module length was not being used we replaced the placeholder we have there for the line number.

Summary:At the moment, to initialize a React Native app, the entire JS bundle needs to be loaded. Parsing JS code takes a while which makes paying for every feature the app has very expensive on start up. Even worse, as the bundle gets bigger and bigger because the app has more and more features, start up time becomes slower.
This rev introduces the few remaining pieces of infrastructure to load JS modules incrementally. This way, on start up we only inject into JSC the modules we actually need. More importantly, by using this piece of infrastructure, the app start up time won't be affected as the JS bundle increases it's size.

Summary:Currently, an empty `<ScrollView />` on iOS always throws the warning "Sticky header index 0 was outside the range {0, 0}".
This is because the error-reporting code relies on the assumption that `stickyHeaderIndices` exists, and when it doesn't the error check thinks there's an index when there really isn't.
Note that this only changes error reporting and won't affect apps out of debug mode.
**Test plan**
I created a sample app and included an empty `<ScrollView />`. Without this change the "Sticky header..." warning was displayed on every run through. With this change implemented, the warning went away.

Summary:When a component prop is set to null/undefined, and doesn't have a default value specified in `getDefaultProps`, the null value is sent over the bridge as a sentinel to reset to the original native value.
On iOS this is handled by creating a default view instance for each view type. The default view is then used to look up the unmodified value for any prop that is reset.
This is rather expensive however, as it means that for complex views (e.g. WebView, MapView), a minimum of two instances will be created even if only one is needed, and the default view will remain even after all actual view instances have been released.
This diff replaces the default view mechanism with a system where the default value of each prop is recorded the first time it is set. This avoids the need to keep an extra copy of the whole view.
The only exception is for props that use the `RCT_CUSTOM_VIEW_PROPERTY` macro, which includes the default view as part of the interface. To avoid a breaking change, a default view will still be created for views that use this macro, but only if they are sent a null value (so very rarely, in practice). In a future update we may deprecate or replace `RCT_CUSTOM_VIEW_PROPERTY` if there are significant benefits to doing so.

Summary:Fixes the RefreshControl layout after a screen rotation. See #6311 for a more detailed explanation. I fixed it by adjusting the frame of the RefreshControl in `layoutSubviews` of the parent ScrollView.
While working on fixing this I noticed that when doing a 'pull to refresh' and then not scrolling and wait for it to end the next one will not behave like the first one (it will require pulling further down for the spinner to start spinning). I fixed that too by scrolling the scrollview back to 0 manually before calling `UIRefreshControl.endRefreshing`.
**Test plan (required)**
Tested using the UIExplorer RefreshControl example.
When doing a pull to refresh and then rotating the screen the RefreshControl must stay positioned properly.
Doing multiple consecutive pull to refresh without scrolling after should all behave the same.

Summary:The UICollectionView example is actually my use-case, which is discussed in a
bit more detail [here](https://github.com/alloy/ReactNativeExperiments/issues/2).
----
This is useful when wrapping native iOS components that determine their
own suggested size and which would be too hard/unnecessary to replicate
in the shadow view. For instance a `UICollectionView` that after layout
will update its `contentSize`, which could be used to suggest a size to
the shadow view.
The reason for adding it to -[RCTShadowView setFrame:] is mainly so it
can be used via the existing -[RCTUIManager setFrame:forView:] API and
because it might not be a feature you want to expose too prominently.
An origin of `{ NAN, NAN }` is used as a sentinel to indicate that the
frame should be used as a size suggestion. The size portion of the rect
may contain a `NAN` to skip that dimension or a suggested value for the
dimension which will be used if no explicit styling has been assigned.
Examples:

Also, the `RUN_RUNLOOP_WHILE()` macro did not actually assert when timing out, and the logic in `- [RCTBridgeTests tearDown];` was broken in such a way that tests would always take 5 seconds to run (and then timeout silently).
