Ensure that a Mozart EntityNode (that corresponds
to an ExportNode) is always released on the
Rasterizer thread.

MZ-259

This reverts commit 86591145.

* Update to new Dart FIDL bindings API.

Fixes https://github.com/flutter/flutter/issues/11586

Without this, the cull rect calculated by an SkPicture may be truncated
to integer pixel coordinates.  The raster cache relies on a precise cull
rect in logical coordinates.

See https://bugs.chromium.org/p/skia/issues/detail?id=6954

Both dart:core and dart:_internal export Symbol. 

This is silently ignored by the VM but some tools (e.g. fasta) report a warning when processing dart:ui sources.

See https://github.com/dart-lang/sdk/issues/30127 for more details.

* fix (with squashed debug stuff)

* clean up

Compute the necessary texture resolution using more accurate scaling
information provided by Mozart scene node metrics events instead of the
device pixel ratio provided by the Mozart view properties (which we
might remove in the future).

This allows us to allocate smaller textures when a Flutter view is
being scaled down.

* Fix Flutter loading from dill files.

* Remove disable of causal async stacks.

* Include mirrors patch files as they are needed for release/profile gen_snapshot

* Free the bytes

* Add FTL_DCHECK

Will make debugging layer trees with PhysicalLayers easier.

Revert "Revert "Reland "Run Flutter on iOS and Android with color correct Skia (#3826)" (#3878)" (#3895)

This reverts commit 1db18a40.

See https://github.com/dart-lang/sdk/issues/29971

This reverts commit 2d9155e1.

Fixes a regression with semitransparent images (flutter/flutter#11169)

This action is triggered when the user swipes (in accessibility mode) to the last visible item of a scrollable list to bring that item fully on screen.

iOS implementation to follow.

Roll Dart to f445c318184b30b3db997ac27f357bcb5d45670a.

Fuchsia issue TO-365

Fixes https://github.com/flutter/flutter/issues/11007

Fix target name for flutter_patched_sdk so it doesn't conflict with patched_sdk target name, doesn't confuse ninja with depfile defined as .d (#3834)

* Revert "Revert "Reland "Run Flutter on iOS and Android with color correct Skia" (#3818)" (#3823)"

This reverts commit db8d8a99.

* Fix test code to match internal API change

* Build Flutter patched-sdk with kernel artifacts

* Switch to new dart_host_toolchain argument mechanism to let dart patch_sdk know of host_toolchain.

* Update dart dependency

* Updated licenses

* Rename dart dependencies tag so they have just 'dart_'-prefixed dart's names.

* Fix indentation and line breaks for newly added deps.

* Add toolchain for windows host

* Update dart revision

* Licenses

* Update licenses

* Revert changes to licenses_third_party

* preserve Window callback zones

Run Window callbacks in the zone they are registered in. This is consistent with how other native API work, such as `scheduleMicrotask`, `Timer`, and `dart:io`. This also enables the developers to use the `Zone` API to capture and log unhandled Dart errors.

* refactor wrapping

* new line

* fewer if checks; group getters/setters/fields

* inline _invokeOnPointerDataPacket

This reverts commit 2650f529.

* Revert "Revert "Run Flutter on iOS and Android with color correct Skia (#3743)" (#3775)"

This reverts commit cfe70e07.

* Enable sRGB on IO thread, too

* Add 4444 as a fallback rendering mode

* Use bare ptr to SkColorSpace (not sk_sp) in PrerollContext

This attempts to make the Canvas API and some related features more
likely to throw a Dart exception than crash when exposed to bad input.

Depends on rolling tonic to
https://fuchsia-review.googlesource.com/c/35742/ which this patch does
not yet do, but I wanted to put it up for review to see if it was even
a reasonable approach.

This allows the shell to be built normally for a Fuchsia host.

* Revert "Fix licenses_lib golden file (#3798)"

This reverts commit d8ac43c3.

* Revert "Remove ParagraphConstriants (#3796)"

This reverts commit 8ccf767f.

* Revert "Reland "Initial integration of libtxt with Flutter alongside Blink." (#3793)"

This reverts commit 3c049219.

ASL was deprecated in iOS 10 and started causing SIGPIPE issues in iOS
10.3. Under the iOS 8 SDK, syslog() stopped working as of iOS 10.3
devices, with the result that ASL stdout/stderr forwarding was the only
means of logging. The engine now builds against the iOS 10 SDK, with
deployment target of iOS 8. Under this SDK, syslog() works correctly
across all supported OS versions.

NOTE: This is a temporary fix to get developers unblocked. While this
does fix the SIGPIPE issue and put iOS logging on par with the Android
solution, the intent is to move to a dedicated communication channel
with flutter_tools that isn't log-based.

* Transition to Hybrid lib/txt and blink text system.
