Reland "[vm/ffi] Add common C types"
We're adding these types to `dart:ffi` rather than `package:ffi` so that they can be used with `FfiNative`s. Adds `NativeType`s for the following C types: * unsigned char * signed char * short * unsigned short * int * unsigned int * long * unsigned long * long long * unsigned long long * uintptr_t * size_t * wchar_t Because the C standard only defines minimum sizes for many of these types, future platforms might diverge from the typical size even if all platforms currently agree on a size. To avoid having to reification later, we define all types as AbiSpecificIntegers rather than typedefs, even if all current target platforms agree on the size. Closes: https://github.com/dart-lang/sdk/issues/36140 TEST=tests/ffi/c_types_test.dart Original patch in patchset 1. * Removes `Char` for now until package:win32 has rolled to 2.3.8 in Flutter. https://pub.dev/packages/win32/versions/2.3.8/changelog https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8824468064587445729/+/u/Android_Views_Integration_Tests/stdout * Adds `c_type.dart` in `ffi_source.gni` which should fix `IntPtr` missing when analyzing `path_provider_linux`. (However, I was unable to reproduce the issue locally.) https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8824468064571399025/+/u/run_test.dart_for_flutter_plugins_shard_and_subshard_analyze/test_stdout `/tmp/flutter_plugins.KZMNMC/packages/path_provider/path_provider_linux$ ~/flt/engine/src/out/host_debug/dart-sdk/bin/dart analyze --fatal-infos` Change-Id: I89130cccba285fc9c483bb53f5710a302f2b104f Cq-Include-Trybots: luci.dart.try:dart-sdk-linux-try,dart-sdk-mac-try,dart-sdk-win-try,vm-ffi-android-debug-arm64c-try,vm-ffi-android-debug-arm-try,vm-canary-linux-debug-try,vm-fuchsia-release-x64-try,vm-kernel-gcc-linux-try,vm-kernel-asan-linux-release-x64-try,vm-kernel-linux-debug-x64-try,vm-kernel-linux-debug-ia32-try,vm-kernel-mac-debug-x64-try,vm-kernel-mac-release-arm64-try,vm-kernel-nnbd-win-release-ia32-try,vm-kernel-nnbd-win-release-x64-try,vm-precomp-ffi-qemu-linux-release-arm-try,vm-kernel-win-release-x64-try,flutter-analyze-try,flutter-engine-linux-try,flutter-frontend-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/229156 Reviewed-by: Martin Kustermann <kustermann@google.com> Commit-Queue: Daco Harkes <dacoharkes@google.com>
