* Handle double-height status bar on iOS

In certain cases, iOS displays a double-height status bar (e.g., when an
application is using device location or while in a call). In such cases,
iOS offsets the app view origin by 20px, reduces view height by 20px,
then overlays a 40px opaque status bar: 20px covering the newly opened
20px gap at the top of the screen, 20px covering the top 20px of the
view, which had previously been under the standard-sized status bar.

Flutter previously set top padding to the height of the status bar,
which resulted in 40px padding with a double-sized status bar. However,
the padding should match the portion of the status bar overlapping the
view, which is 20px.

Note that the final case is the one in which no status bar is shown and
padding should be zero.

* Only apply status bar padding on root views

Adapt to refactoring of snapshot APIs in the Dart VM.

Add MultiLicense license class

Generated by pub in tools/licenses for license aggregation.

fixes flutter/flutter#6865

The first 23 lines of the BoringSSL license contain informational text
including Buganizer issue numbers that is not part of the license text
itself.

* Add OpenSSL as supported licence type

Adds special handling for the OpenSSL licensed files under BoringSSL.
Specifically, some of the ARM assembly files in the latest Dart SDK are
dual-licensed with OpenSSL.

* Support blocks that ref by type with no copyright

The upcoming Dart SDK includes files (e.g., sha256-armv4.S) with a block
that specifies teh code is dual-licenced under OpenSSL, but doesn't
include a copyright date of its own.

The GPUSurfaceGL holds references to Skia objects that may own GL objects.
If the GL objects are destructed on the GPU thread after the EGL context has been
dropped, then the GL delete calls will not take effect.

Added a Paragraph.didExceedMaxLines property to query when this occurs.

Previously, search by license type only searched the contents of the
chain of direct ancestor subdirectories. This change broadens the search
to the full subtree of the current license root when no license is found
in the chain of direct ancestor directories.

On macOS diff -u6 results in:
  diff: `-6' option is obsolete; use `-U 6'
the latter syntax is supported on both Linux and macOS.

Add a couple missing newlines.

Not shipped to clients.

Fixes https://github.com/flutter/flutter/issues/7200

Add a getter for flutterView in FlutterActivity. This allows fullscreen flutter apps to extend FlutterActivity and do custom stuff with the flutter view. (#3324)

The API was updated recently so platforms can report memory usage for the
rasterizer to display as an overlay.

The Skia team says these APIs are outdated and should be removed. They
do not appear to have any clients.
