* Update to mojo ba13534f2b2af27a1d73e176f7406dbab25f8e14
* Fix build for updated mojo
* Fix android build. Undo some of the mojo roll.
* Fix iOS build.
Previously we enabled accessibility unconditionally on iOS, which is more
expensive than necessary. We still enable it unconditionally on the simulator
because there's no API for determining whether accessibility is needed on the
simulator.
These classes now use the same terminology and work in the same way.
Also, change semantics.mojom to use an enumeration of actions instead of
having a separate method per action. This will hopefully scale better.
1) Add ability to specify a system UI overlay style, to
provide a hook into the style of the status bar icons on iOS.
2) Migrate the Activity service's task description API to the
system chrome platform service. The old API will be removed
once the Flutter repo is updated to use the new API after an
engine roll.
flutter/flutter#3544
This patch makes the FlutterViewController interface more idiomatic by not
retaining listeners. It's the callers responsibility to make sure the lifetimes
work out.
Earlier, the dynamic service loader was part of the main application
bundle. But now, we package it into Flutter.framework and let the user
control "main". The old path was looking for the manifest in the wrong
spot.
* Move node implementation to Objective C
This changes AccessibilityBridge::Node (C++) to be AccessibilityNode (objc)
in order to have the nodes returned directly as ui accessibility elements.
This buys us a few things:
1) We can now return an element tree instead of a flat list, thus negating
the need to maintain a global rect and global translation
2) We use less memory since we don't need to instantiate both nodes and
their ensuing accessibility elements
3) accessibility elements can now implement the methods necessary to respond
to events like user scrolling

After this patch, main_ios.mm now consumes Flutter.framework via public APIs.
This patch prepares us to move Flutter on iOS over to consuming
Flutter.framework as a binary artifact.
All the headers for Flutter.framework are now in framework/Headers and all the
source files for Flutter.framework are now in framework/Source. Previously it
was unclear that FlutterAppDelegate and main_ios.mm weren't part of
Flutter.framework. (They still build as part of the framework, but that's
something I'll fix in a later patch.)
