Added a unit test too.

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).

That GM has a path with 16k points, arranged in a rectangle. When we try
to draw it in Ganesh, we first check to see if it's a (closed) rectangle.
We eventually decide that it is a rectangle, but not closed, so it gets
passed along. Then we construct a GrShape, which tries to simplify the
shape, again asking if it's a rectangle...
Each isRect query was iterating over the 16k verbs, and for each one,
calling atVerb(i). That, internally, calls verbs(), which calls validate()
in debug builds. So we were walking all 16k points 16k times (to ensure
the bounds were correct). The end result is that the GM took over 11
seconds to draw, and now takes 3 ms.

As a part of serializing SkPaths, I want to be able to know (without
asserting) whether or not a path is valid so that I can discard
potentially malicious deserialized paths.
Currently, SkPath(Ref) both just have asserting validation functions
which can't be used externally. This patch adds accessors that don't
assert.

Note that this does not clean up the users of this function, which
may themselves be subject to other overflow issues.
