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.

This is a performance-only hint that no one but fuzzers
is using. It's even explicitly filtered out in Android.
The fuzzers have noticed they can trick us into allocating
uninitialized memory and treating it as opaque, blending
uninitialized pixels, etc.
Since no one's using this, we can just kill the bit.

After this CL, we have 3.5 options for fuzzing ImageFilter
1. Create it from API calls and then draw it
fuzz -t api -n ImageFilter -b [input]
2. Deserialize a fuzzed stream into an ImageFilter (this is
what Chromium's filter_fuzz_stub does)
fuzz -t filter_fuzz -b [input]
3. Create an ImageFilter from API calls, serialize it, apply
some mutations to the stream, deserialize it, then draw it.
fuzz -t api -n SerializedImageFilter -b [input]
3.5 Create ImageFilters as part of our more general canvas
fuzzers.
fuzz -t api -n RasterN32Canvas -b [input] (and others)
Previously, the SerializedImageFilter had its own, slightly
stale and prone to stack-overflow way of making an image filter.
This CL re-uses what we already do for Canvas fuzzing and removes
that dead code.
Additionally, there is a way to easily generate a corpus
for the filter_fuzz type, via SerializedImageFilter.

This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

On desktop, this saves just over 5% of the time in the SkSL compiler.
As written, the code will now build either way, so it's much easier to

required).

Previously, SkGifCodec treated an error in the LZW data as incomplete,
since we can still draw the partially decoded image. But a client doing
incremental decodes needs to distinguish this from truly incomplete
data. In the case of an error, the client should not attempt to provide
more data and decode again.
Add kErrorInInput, and return it when SkGifCodec sees a fatal error.
Treat it the same as kIncompleteInput when it comes to filling and DM.
