Outer projects can just set() the option / setting before calling add_subdirectory() on Dawn.
Also provide a build directory for Dawn's third_party dependencies. Allows the outer project to specify a third_party directory that's out of the dawn tree.

Enabling particular fuzzers requires that certain other CMake options
are enabled. For example, enabling the SPIR-V Tools fuzzer requires
enabling the CMake option for building spirv-fuzz. This change uses the
FORCE parameter to force the CMake cache to be overridden in such cases.
The change also adds FORCE to other options where it seems appropriate,
and improves some doc strings associated with CMake options.

This change adds a new tint fuzzer that uses SPIRV-Tools to fuzz SPIR-V binaries.
The fuzzer works on a corpus of SPIR-V shaders. For each shader from the corpus it uses
one of `spirv-fuzz`, `spirv-reduce` or `spirv-opt` to mutate and then runs the shader through
the Tint compiler in two steps:
- Converts the mutated shader to WGSL.
- Converts WGSL to some target language specified in the CLI arguments.
The list of all supported CLI arguments and their description is in the cli.h file.

With all tests converted to WGSL we only use shaderc to assemble SPIRV
assembly to binary. shaderc requires glslang but we don't use it at all.
By using SPIRV-Tools directly to assemble SPIR-V, we can remove both the
shaderc and glslang dependencies.

This reverts commit 9fdbb74072.
Reason for revert: The SPIRV-Cross GN files have a bug which is fixed upstream, but Skia is on an old version of SPIRV-Cross so they don't have the fix. So, the build fails when rolling Dawn into Skia complaining about unknown `-fno-exceptions` on the windows bots. Need Skia to either move to vulkan-deps, or roll their spirv-cross forward before this can re-land.

The third_party/khronos folder is directly commited into the Dawn repo.
This means it isn't really move-able to a different third_party folder
but it still uses the `DAWN_THIRD_PARTY_DIR` variable. This makes it
difficult to change where the rest of the third party code lives.
This CL changes the `third_party/khronos` references to use

The basic change was to copy-paste targets in the new BUILD.gn files and
fixup paths / add includes. There's a couple more changes that had to be
done at the same time:
- Multiple files need to know if GLFW is supported so the variable was
moved to dawn_features.gni.
- The gtest_and_gmock target used to abstract between Dawn's copy of
GTest/GMock is only needed by tests and was moved in src/tests/BUILD.gn.
- A leftover dawn_end2end_tests target is left in the main BUILD.gn
file that is an exact copy of the on in src/tests/BUILD.gn. This is
because the GN path is hardcoded in Chromium's isolate_map.pyl that also
can't support GN groups. The only way to move a target I could figure
out was to duplicate it temporarily.

For some unknown reason, during the Chromium build, the

nothing actually references is (as is the case for "is_fuchsia ==

This ends up in a build failure, since glfw doesn't support this

This CL is a work-around that makes the library empty for Fuchsia
instead. Note that this is never linked into anything so should

The Fuchsia platforms relies on a number of Vulkan extensions
that have not been upstreamed to Khronos yet, and thus are not
part of the official Vulkan headers (i.e. <vulkan/vulkan.h>).
This CL adds a new header under src/common/ that contains these
declarations, extracted from the Fuchsia source tree, and ensures
they are included automatically from <common/vulkan_platform.h>
This is necessary to support certain features when building
Dawn on Fuchsia.
IMPORTANT NOTE: Some of the things declared in this header will
change once everything is upstreamed, which will require updating
the source code using them. For example,
VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_TEMP_ZIRCON_EVENT_BIT_FUCHSIA
Will likely be renamed officially as:
VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_ZIRCON_EVENT_BIT
And will be assigned a new value by Khronos.

This CL adds in fuzzers for SPIRV-Cross for HLSL, GLSL, and MSL
outputs. These fuzzers live in Dawn because there is not appropriate
location in the Chromium source repo for them and it is unlikely they
would be land-able in the SPIRV-Cross repo, because it is not coupled
with Chromium's build system and thus Clusterfuzz so would be
effectively dead code. Dawn depends on this code, but it is also
integrated into the Chromium build system, so this was the best place
I could find for them
The code under fuzz unfortunately uses exceptions/aborting as its
error reporting mechanism. This is an acknowledge short coming and
there are efforts to remove this behaviour. To work around this and
reduce the number of false positives found by the fuzzers, a signal
trap has been implemented which will be removed once the code under
fuzz has been updated.
The trap replaces the existing signal handler and silencing signals
while running the code under test. This allows the code under test to
call abort() and not crash the fuzzing process. Theoretically, only
SIGABRT should need to be trapped, but something is causing the signal
from abort() to be converted to SIGSEGV when running under ASAN.
This signal trap has been tested with the fuzzing/sanitizers by
intentionally inserting bad calls that will occur after a few thousand
test cases. It was confirmed that the fuzzer detected the issue and
stops fuzzing.
The alternate to implementing this signal trap would be to turn on
exceptions for the fuzzer. This was attempted, but proved to be
fruitless due to what was reported as an ODR issue, but couldn't
couldn't be silenced. The likely underlying issue was a pre-built
library or other object being built without exceptions was causing
different versions of symbols or the exception version of the standard
library not being instrumented by ASAN. Given the majority of Chromium
eco-system turns off exceptions, fixing this issue would not be
helpful to the larger community and was looking like it would require
significant effort.

As a byproduct, Empty.cpp is no longer needed and is removed.
Also moves the TerribleCommandBuffer to utils:: because it isn't part of
the implementation of the wire, renames dawn::wire to dawn_wire, moves
src/wire to src/dawn_wire and puts the interface of dawn_wire in
src/include/dawn_wire.
The interface exposed by libdawn_native is declared in the new headers
living in src/include/dawn_native so that they both the users and the
libraries use the DAWN_NATIVE_EXPORT macros.
This was because the clip space of OpenGL has an inverted Y compared to
other APIs. This commit:
- Updates SPIRV-Cross to the latest version
- Uses the new vertex.flip_vert_y option in ShaderModuleGL
- Enables tests that are now passing in GL.
* clang/gcc: enable -pedantic warnings
* suppress a GCC-specific warning in stb_image
* And some clang-specific warnings
* -Wconversion (clang) -Wold-style-cast (clang+gcc)
and fix a few warnings that show up with these (and a few more with
-Wconversion on gcc, even though that's not enabled by default)
* bunch more warnings
* fixes
* remove merge error
Adds the swap chain interfaces to the API without changing the behavior
of anything else. This includes the C APIs for applications to provide
swap chain implementations. Also adds stub implementations on every
backend.
This helps Visual Studio users have less clutter in their solution
explorer. This also updates spirv-tools to a newer version that folders
itself. This also updates spirv-headers so that spirv-tools compiles.
Visual Studio 2017 is able to build CMake-based projects directly be
opening the folder containing the CMakeLists.txt. However when doing
this shaderc is not able to find the Python executable (it uses
find_program instead of the special Python CMake module). Help shaderc
by setting the PYTHON_EXE variable before including its CMakeLists.txt
For shared library to work on Windows to work, we need to add
declspec(export) and declspec(import) annotations to the symbols to
export. This fixes the problem by making all libraries static on
Windows, but we'll need to revisit and do proper symbol exports.
