channel closure.
This CL resets the state including cleaning up the buffers whenever
a fuchsia.ui.pointerinjector.Device channel closes due to some error.
Test: flutter_runner_tests
Eliminate a few uses of memset in the code, replacing them with C++
alternatives, like using initialiser list syntax and std::array + fill.
This avoids some double-hardcoding of array length in the code.
This adds a dart_entrypoint field to FlutterDesktopEngineProperties in
the public C Windows API, which mirrors that in the embedder API.
When a null or empty entrypoint is specified, a default entrypoint of
'main' is assumed. Otherwise, the app is launched at the top-level
function specified, which must be annotated with
@pragma('vm:entry-point') in the Dart source.
This change is backward-compatible for existing users of the Windows C API
and the C++ client wrapper API. To avoid breaking backward compatibility,
this patch preserves the entry_point parameter to FlutterDesktopEngineRun
in the public Windows C API as well as in the FlutterEngine::Run method
in the C++ client wrapper API. The entrypoint can be specified in either
the engine properties struct or via the parameter, but if conflicting
non-empty values are specified, the engine launch will intentionally fail
with an error message.
This change has no effect on existing Flutter Windows desktop apps and no
migration is required, because our app templates never specify a custom
entrypoint, nor was the option to specify one via the old method particularly
feasible, because the FlutterViewController class constructor immediately
invokes FlutterViewControllerCreate which immediately launches the engine
passed to it with a null entrypoint argument, so long as the engine is not
already running. However, running the engine without a view controller
previously resulted in errors due to failure to create a rendering surface.
This is a followup patch to https://github.com/flutter/engine/pull/35273
which added support for running Dart fixture tests with a live Windows
embedder engine.

Adds a new header, flutter_macros.h which includes a FLUTTER_DEPRECATED
macro that can be used to mark deprecated API as such, with a
hopefully-informative message, ideally describing the expected removal
version and any migration tips.
This will need to be #included in flutter_windows.h and flutter_linux.h,
but prior to doing so, we'll need to update the engine recipe to bundle
the new header, here:
https://flutter.googlesource.com/recipes/+/refs/heads/main/recipes/engine/engine.py#1457
No tests since this adds a compiler macro that will be used for future
C/C++ API deprecation once the above recipe change has landed;
specifically: FlutterDesktopEngineProcessMessages.

Fixes a minor whitespace inconsistency on the documentation for
FLUTTER_EXPORT.
No test change since there is no change to code semantics.

This PR takes a step back and changes the GTK IM client window back from FlView to GtkApplicationWindow as it was before #33111. The window was originally changed to FlView to make the code testable by cutting a dependency to gtk_widget_translate_coordinates(). The change was hard to revert because there were several conflicting changes on top. Therefore, this PR introduces an FlTextInputViewDelegate to be able to provide coordinate mapping in a testable way.

This adds support for running end-to-end tests that use a live engine to
run Dart test fixtures. This enables testing the public Windows C API in
//flutter/shell/platform/windows/public/flutter_windows.h
This only adds support for a single test entrypoint (main). A followup
patch will add support for this. See:
https://github.com/flutter/flutter/issues/93537
Issue: https://github.com/flutter/flutter/issues/87299
All Flutter engines in the same process share a common Dart VM, which is
launched with the start of the first engine in the process and should be
terminated when the last engine in the process has been deallocated.
Formerly, it was not possible to cleanly shut down and restart the VM in
a process, but this was resolved in the Dart SDK and a flag exposed in
flutter/engine#10652. Since some embedders take advantage of the fact
that the VM remains running after engine shutdown, this flag is not
enabled by default, however it should be enabled for the Windows
embedder, which we control.
No tests added since this is not testable via any API to which the
Windows embedder has access. The behaviour of this flag is tested in the
embedder API tests in `EmbedderTest.VMShutsDownWhenNoEnginesInProcess`
in shell/platform/embedder/tests/embedder_unittests.cc.

In flutter/engine#35106, I landed a parameter type fix for the
declaration of FlutterDesktopEngineGetTextureRegistrar in our public
Windows C API. I also added a unit test that called this function.
That function (and all others) in our public Windows API is marked
FLUTTER_EXPORT, which resolves to __declspec(dllexport) or
__declspec(dllimport) depending on whether FLUTTER_DESKTOP_LIBRARY is
defined. It can be defined by adding the following build config:
//flutter/shell/platform/common:desktop_library_implementation
If the function is marked as an import, we get linker warnings that
we're importing a function that's defined in the same executable image.
This patch resolves this by marking the functions as export.
An alternative fix would be to support a third macro resolution that
resolves to nothing in the presence of some definition like
FLUTTER_NO_EXPORT; however, since flutter_export.h is a public header,
I'd prefer not to complicate it further, and this is a unit test that
can't be linked against either way.

No new tests since this simply fixes a link warning message in unit tests.
