The SkFontData type is not exposed externally, so any method which uses it can be updated to use smart pointers without affecting external users. Updating this first will make updating the public API much easier. This also updates SkStreamAsset* SkStream::NewFromFile(const char*) to std::unique_ptr<SkStreamAsset> SkStream::MakeFromFile(const char*). It appears that no one outside Skia is currently using SkStream::NewfromFile so this is a good time to update it as well.
