For the longest time, the libfuzzer binaries used by oss-fuzz
were just hacked onto the BUILD.gn file. This removes that patch
and makes them buildable from Skia proper.
After this, there should not be any modifications oss-fuzz needs
to do to a Skia checkout before it builds and runs.
Of note, oss-fuzz will define skia_use_libfuzzer_defaults to be
false so it can control those flags with more finesse (e.g.
fuzz with ASAN, fuzz with hong fuzz instead of libfuzzer). I
added on skia_use_libfuzzer_defaults so that a normal developer
gets something that works by default.

Golden SkSL outputs are intended to eventually replace the majority of
our unit tests, since they can automatically update themselves when we
change implementation details of the compiler.
If you change the compiler output without updating the Golden files, the
CheckGeneratedFiles housekeeper will be triggered. Set
`skia_compile_processors` or `skia_compile_sksl_tests` to true in your
GN args to regenerate them.
Almost all of the tests from SkSLFPTests.cpp and SkSLGLSLTests.cpp can
be migrated into separate unit-test .fp/.sksl files in a followup CL.
hcm@ has signed off on removing the copyright boilerplate preamble from
our unit test files.

This saves about 15kb of wasm code size (4kb gzipped), 11kb
of JS code size (2kb gzipped) and about 10ms
when creating a new surface (~35ms -> 25ms in a local test).
This also gates the webgl code more strongly (off unless you
really request it), since the headers won't be available
except in an emscripten environment.

Explanation: The sksl standalone compiler is used to convert the raw
(text) SkSL pre-includes into a "dehydrated" binary format. It also
(previously) depended on those files, as they were #included and used,
unless a special #define was changed. This created a dependency cycle
that we hid from GN (by lying about the outputs of the dehydrate step).
As a result, builds would never reach steady-state, because the compiler
would be rebuilt (due to the newer dehydrated files), and then the
dehydrated files would be rebuilt (due to the newer compiler).
This CL changes the logic so that the standalone compiler always uses
the textual pre-includes, and no longer depends on the dehydrated binary
files. Thus, to make any kind of change to the dehydrated files (whether
due to pre-include changes, or the encoding format itself), you just
need skia_compile_processors enabled. The dependencies are now honestly
communicated to GN, and we reach steady state after one build.
The NOTE above is because GN/ninja cache the dependencies of each
target, and will still think that the SkSLCompiler.obj linked into the
standalone compiler depends on the dehydrated files, at least until one
successful build, when it will realize that's no longer true.
Reland notes:
The bots originally rejected this CL, because SkSLCompiler was
hard-coded to load the text files from a relative path that assumed the
executable was in "<skia_checkout>/out/<some_dir>". That's not true for
bots, and it was fragile, even for users. Now, we use GN to directly
generate sksl_fp.sksl, and copy all of the other pre-includes to the
root out dir (working directory when running skslc). This means we
no longer need to generate the sksl_fp.sksl file into the src tree, and
the compiler can more safely assume that the files will be in the
working directory.

This speeds up compiler construction, because we no longer have to parse
and process a bunch of SkSL source code during startup.

This is an attempt to fuzz the usage of SkSurfaceCharacterization,
SkDeferredDisplayRecorder, and SkDeferredDisplayList.
This fuzzer first makes a surface and characterization from
GrDirectContext and then create a DDL and draw it on the surface.
The code is compiled with ninja and run with AFL at the speed around
600/sec
The future changes will include:
1. An alternative way to create DDL: first create the surface and
extract the characterization from that existing surface.
2.currently we just pass the ownership of the DDL into draw_ddl. In
the future we should add a version that retains ownership of the DDL
in order to fuzz the lifetime of the DDL.
3. Refactorize line 62-119

SkTypeface_FreeType uses SkFontData and makeFontData as a way to lazily
create FT_Face objects. Other SkTypeface types do not need this, so
remove it.

I spent a little time working on adding the --dylib JIT
mode to Windows where we'd shell out to Clang to make a .dll,
but then I remembered this VTune JIT API.
That dylib approach is nice for working with a wide range
of tools (perf, Instruments, gdb, etc.), but when your only
need is Vtune, this API is actually the best option. You
get your profiler aware of your JIT'd code with way less
overhead than the shell-then-dlopen approach.
If we need to expand to more tools I'll go make the dylib
mode work, but I think this is good enough to make me happy
on Windows for now.
This should look really similar to

The major improvement is that now the fuzzer is able to execute
the sksl code (before it just compiled it). The fuzzer will
reserve 256 bytes for providing uniforms to the shader;
meanwhile, the fuzzer will read the remaining bytes as sksl code
to create SkRuntimeEffect. It then creates a shader and executes
it by painting the shader on a canvas.
The code was tested locally with afl-fuzz, and the execution
speed was around 700/sec.
An alternative implementation would have been using Fuzz.h to
read bytes; I decided to go with sk_sp<SkData> since it has a
comparable format to other binary fuzzer and meets all the
functionality in this fuzzer.
For future changes, there are 2 important improvements to the
implementation:
1) Current shader does not have children shaders; thus,
makeShader() will fail if the SkSL ever tries to use an 'in shader'.
As pointed out in patchset 11, after creating the runtime effect,
effect->children().count() will tell you how many children it's
expecting (how many 'in shader' variables were declared). When you
call makeShader(), the second and third arguments are a
(C-style) array of shader pointers, and
a count (which must match children().count()).
Some helpful examples can be SkRTShader::CreateProc in
SkRuntimeEffect.cpp, make_fuzz_shader in FuzzCanvas.cpp.
2)
In this fuzzer, after creating the paint from a shader, the paint
can be drawn on either GPU canvas or CPU, so a possible way is to
use SkSurface::MakeRenderTarget to create GPU canvas and use a byte
to determine which canvas it will be drawn on.

Previously, doing an official build of Skia with Vulkan and particles
enabled would succeed in compiling all of skia.lib, then fail to find
Vulkan headers for two particle .cpp files (that reach GrVkVulkan.h
via SkSL headers).
