In XPIDL, the return type of AddRef and Release are nsrefcnt, which is defined as unsigned long. The first problem is that nsrefcnt is defined in XPIDL as unsigned long, but in C++ as uintptr_t. The second problem is that the actual return type of these methods in C++ is MozExternalRefCountType. This patch fixes the return type of these methods in XPIDL. However, due to MSCOM compatibility requirements this type is not expressible in XPIDL, so I added it as a new builtin type to XPIDL. In C++, it defers to the typedef and for Rust it uses u32 directly. I tried using the new Rust typedef I defined in refptr.rs, but it seemed like it was being used in places that didn't have refptr.rs available. I also deleted the incorrect definition of nsrefcnt in XPIDL. It is not used anywhere else in XPIDL files, and my previous patches removed all uses of this type definition from Rust. Note that this patch does not really change nsISupports.h, because this part of the file is ignored via an #if 0. However, this patch does clear the way for further work to start using the auto generated nsISupports.h instead of nsISupportsBase.h.
