This changes how the `nsIStringInputStream` interface is initialized in C++ code to make it support larger stream sizes better. This involved moving away from using nsCString in some cases, as it has a maximum string length of approximately 2GiB. This also required changing the signature of one of the methods making it no longer JS-compatible. As the `setData` method was awkward to use from JS anyway, the method was split into two (one for C++ callers, and one for JS callers), and renamed. This required changes to the various JS callers.
