34241299d1 Control growth of FuzzNicePath with chain of path transforms
The test case was producing a stack trace of sequential path transforms.
While each individual call would check to see if the path is too big
and return, the resulting path kept getting continually bigger as we
transformed it again and then popped the stack. This CL changes it to
skip the transform op if the returned path is already too big.

db1d93f3b4 Stop timeout in api_mock_gpu_canvas.
Large paths can lead to large processing times for path effects and
hence timeouts.

Also re-enables ShrinkToFit test until that code is finally removed,
but using the PathPriv interface instead.

This simplifies the fuzzer (since the important logic
is in FuzzCommon.cpp).

f1f1e7dd36 Hide shrinkToFit -- not needed now that we have pathbuilder
Step one is to make it private -- only skottie needs it at the moment
Stpe two is to modify pathops to use builders, and then we can likely
remove it shrinkToFit entirely (since builder.snapshot() is already snug).

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

3d6b438b99 remove legacy pathref validation
Chrome added a public method to validate SkPathRef,
but always called it when validating SkPath. We did too.

Remove the SkPathRef entry point, validate SkPathRef
when validating SkPath, and remove Skia's callers.
(Chrome has already been fixed.)

f88f5ef109 simplify nextRange(), fold in nextEnum()
Doesn't look like we need to distinguish these if we just
write them as the simple

   1) load the right number of bytes
   2) clamp to [min,max]

This makes enum fuzzing independent of its underlying type, and may make
it easier to see the mapping from fuzzed byte stream to
nextRange()/nextEnum() values.

7ffa40cedb FuzzPath -> FuzzNicePath
This CL renames FuzzPath() to FuzzNicePath() to remind us that it's
meant to create paths that a user could reasonably want to create
in good faith, to pass to Skia via its API, etc.

Then, add fuzz_nice_rect(), and have FuzzNicePath() use that to create
its rectangles and use FuzzNiceMatrix() to create its matrices, just
like we already use FuzzNiceRRect() to create rounded rectangles and
FuzzNicePath() itself to create sub-paths.

Using fuzz_nice_rect() should be the fix for the attached bug.
Using FuzzNiceMatrix() is by analogy, more preemptive.

While we're at it, rename BuildPath to FuzzEvilPath, so the contrast
with FuzzNicePath is more clear.

Update the assertions that we create a valid path in FuzzNicePath()
to tell us where things went wrong if they do.

bc9a1a837d Make fuzz::next overloads more consistent
Some oss-fuzz bugs (like the linked one) would not reproduce
in Skia proper due to the fact that there were subtle overloads
of the various Fuzz::next() methods in FuzzCanvas.cpp that
were pulled in in Skia proper, but not oss-fuzz.

This puts all of them in to FuzzCommon.h and makes the
matrix and rrect ones opt-in (fuzz_matrix, fuzz_rrect).

Additionally, this renames fuzz.cpp -> FuzzMain.cpp so we
can properly include Fuzz.cpp in oss-fuzz without
having two mains.
