493f89e577 [fuzz] Standardize, document, and backport fuzzing defines.
We had several defines around the code base that were not
very descriptive. Additionally, we had a patch of extra
runtime restrictions living in oss-fuzz that were applied
when fuzzing over there for some fuzzers.

This has all be consolidated and controlled via the defines
documented in site/dev/testing/fuzz.md

As such, we can remove one of the patches that is in oss-fuzz,
taking us closer to being able to fuzz in the CI/CQ.

PS 1 renames existing fuzz defines to the new schema.
PS 2-3 backports skia.diff from oss-fuzz and changes those
definitions to have the _GREATLY modifier.
PS 5+ further condenses the defines so that there is one
define for gating the runtime checks.

bcfc554fde Add GrDirectContext arg to SkImage::readPixels
Note: The polarity of the staging flag is inverted from usual because
a G3 dependency with no SkUserConfig.h relies on the legacy API.

Once this lands, we will migrate them and others, then remove the
staging API. The inverted staging flag is kind of nice, actually - I may
use that pattern in the future. It means less total CLs and it's just as
easy to flip the bit on or off during debugging.

a008b0fa8b Enable ClangTidy check readability-redundant-smartptr-get.
To my surprise, this even works with homegrown smart pointers (such as
SkTLazy).

https://clang.llvm.org/extra/clang-tidy/checks/readability-redundant-smartptr-get.html

Find and remove redundant calls to smart pointer’s .get() method.

Examples:

  ptr.get()->Foo()  ==>  ptr->Foo()
  *ptr.get()  ==>  *ptr
  *ptr->get()  ==>  **ptr
  if (ptr.get() == nullptr) ... => if (ptr == nullptr) ...

Keep the same default value, but add a (private) API to change it when

a4b9169fb6 Remove 'in' variables from SkRuntimeEffect
Runtime effects previously allowed two kinds of global input variables:
'in' variables could be bool, int, or float. 'uniform' could be float,
vector, or matrix. Uniform variables worked like you'd expect, but 'in'
variables were baked into the program statically. There was a large
amount of machinery to make this work, and it meant that 'in' variables
needed to have values before we could make decisions about program
caching, and before we could catch some errors. It was also essentially
syntactic sugar over the client just inserting the value into their SkSL
as a string. Finally: No one was using the feature.

To simplify the mental model, and make the API much more predictable,
this CL removes 'in' variables entirely. We no longer need to
"specialize" runtime effect programs, which means we can catch more
errors up front (those not detected until optimization). All of the API
that referred to "inputs" (the previous term that unified 'in' and
'uniform') now just refers to "uniforms".

940070122a add create ddl fuzzer
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

a5783f3858 Add SkRuntimeEffect Fuzzer
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.
