After pre-roll we know if there have been any mutations made to the IOS embedded UIViews. If there are any mutations and the thread configuration is such chat the mutations will be committed on an illegal thread (GPU thread), we merge the threads and keep them merged until the lease expires. The lease is currently set to expire after 10 frames of no mutations. If there are any mutations in the interim we extend the lease.
TaskRunnerMerger will ultimately be responsible for enforcing the correct thread configurations.
This configuration will be inactive even after this change since still use the same thread when we create the iOS engine. That is slated to change in the coming PRs.
* [flutter_runner] Reland "[flutter_runner] Improve frame scheduling"

* fix stuff
The compositor context owns the session connection. The creation of the
session connection also does the initial present to clear the node
hierarchy. This present was happening perviously on the platform task
runner while all subsequent presents were on the GPU task runner. This
has now been rectified so all presents are on the GPU task runner.
BUG: FL-288

Use fdio_ns_connect to connect to services in a namespace. For pure
persistant fidl services the old path of creating a file descriptor and
then opening a channel to that file descriptor doesn't work.
We should provide a way to directly connect to a service without first
treating it as a file.
Test:
* workstation.frank, reboot button on main menu works.
* astro, device_settings "erase user data" reboot works.

When |OS_FUCHSIA| is defined (even when |FUCHSIA_SDK| is defined as
well), use the Fuchsia SDK trace macros rather than the Dart timeline.
Reasons for doing this include:
Fuchsia's trace macros support categories. This allows one to
distinguish between (e.g.) "flutter" and "skia" trace events for trace
recording and trace visualization.
Fuchsia has existing in tree benchmarks that depend on finding certain
events under category "flutter".
See the Fuchsia performance mailing list discussion for more context.
* Use manifest file to better replicate the existing build
Also fix app/bin error
* Add remaining shit
* patch in the remaining stuff
* Update BUILD.gn
* Basic structure for flutter_jit_runner far
- Added a package_dir gni that copies the dir structure.
- Doesn't support a lot of the existing functionality.
- Added a script to copy paths.
* pick libdart based on flutter mode
* fix licenses
This is part of a bigger change that will facilitate us
to act on this `RasterStatus`. The specific case is where
after pre-roll we might decide to want to merge the threads
and re-submit the frame -- `RasterStatus::kResubmit` can then
let us achieve this result.

This re-enables unhandled Dart error handling in Flutter applications,
which was removed in a76b958.
The error handling as originally landed was unsafe. Specifically, in the
case where the unhandled error handler was triggered during shutdown,
there was a race condition which could cause a crash in the following
scenario:
1. Runner::OnApplicationTerminate() is triggered, which posts a task to
the application's platform thread will free the Application instance
and terminate the platform thread.
2. Before that task is serviced, the unhandled error handler is called
(by hooks.dart -> window.cc -> ui_dart_state.cc) on the UI thread.
3. The kill task is serviced and the Application dtor and Thread::Quit()
are called, terminating the platform thread.
4. The unhandled error handler attempts to post a task to the platform
thread, whose thread was killed in step 3. This triggers a crash.
Fixing this requires a mechanism for the message loop to know that the
associated thread has been terminated out from under it.
This patch adds mitigation for this scenario, but remains
non-threadsafe/racy. We pass the unhandled error handler a weak pointer
to the Application and check it before posting a task to the platform
thread. This has two issues:
1. WeakPtr isn't threadsafe, and assumes that all operations occur on a
single thread. We're checking its value (which is mutated on the
platform thread) on the UI thread without synchronization.
2. Even with a guarantee that the WeakPtr state were synchronized,
there's a window between when we check the weak pointer and when we
post to the platform thread in which application shutdown and thread
destruction may occur.
This unsafe mitigation is being landed in order to unblock a high
priority bug (FL-256) on a short schedule, and a proper refactoring will
be required to make this properly threadsafe.

This informs the vulkan driver that we're creating an image

decide to use different memory requirements based on the if
memory for the image can be exported or not.

* Scenic `Metrics` no longer supports operator==; instead we use
`fidl::Equals()`.
