Issue flutter/flutter#9594
* 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
**This is a breaking change on iOS**
Previously, the `paused` state was entered when the application resigned
active status. `inactive` now maps to this status. `paused` now maps to
an app that has been backgrounded.
`inactive` is currently emitted on iOS only and corresponds to iOS's
foreground inactive state.
Current state transitions are:
`resumed` <--> `inactive` <--> `paused`
suspending is currently emitted on Android only and corresponds to the
transition to Android's stopped state.
Current state transitions are:
`resumed` <--> `paused` --> `suspending` --> `resumed`
These transitions may change in future.
* This allows the tests to add their own FLX files but still use consistent fonts.
* The test fonts are only embedded on the desktop test shells. The option is not available on mobile platforms.
* Right now, all fonts will resolve to the test font. If we want tests to be able to use the fonts they embed in FLX files but use the test font for platform fallbacks, we will need to add font selector fallbacks. I can do this in an another patch. So far, there are no users of this functionality.
After this patch, platform messages now take the same path through the system
that semantics data does (on Android). Support on iOS will be in another patch.
This patch prepares us to switch sending semantics information over mojom to
using dart:ui directly. Currently the recorded information is dropped on the
floor, but that will improve in future patches.
We now use JNI rather than Mojo to transport pointer data from Java to Dart.
Also, fill in a few more of the pointer data fields from information in Java.
Rather than using mojom to encode pointer data, we now encode and decode it
manually. A future patch will remove the mojom codepath once the framework is
updated.
* Namespaces have been updated to reflect the move from //flutter/sky/shell to //flutter/shell.
* shell/BUILD.gn file has been split into smaller GN files for each subcomponent of the shell (common, GPU, diagnostic, testing).
* GN dependencies have been rewritten to stop exposing common shell dependencies as public. Duplicates have also been removed.
* GPU subcomponent has been updated make it more suitable for Vulkan integration.
* The GLFW backend has been resurrected.
