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).
