This should make reproducing certain fuzzes easier between oss-fuzz
and a typical dev's desktop.
This was the most straight-forward way I could think of to
accomplish this. An ideal solution would "compile" a set of
fonts that was not the test set and embed it, but I lack the
domain knowledge to craft such a set.
If this method works ok, we can explore making the font set
more robust and varied.

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.)

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.

I think this originally was done due to int / unsigned
differences between Linux in Windows. In hindsight, that
was short-sighted.

Fuzz SkAndroidCodec to help to catch errors in both incrementalDecode
and scanlineDecode. Try a variety of sample sizes, but cap it at 64.
Though sometimes larger sample sizes are used, the lower ones tend to
more common. Also draw the resulting bitmap to verify that we
initialized all pixels.
Independently test incrementalDecode to ensure that it initializes
rowsDecoded.

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.

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.
