Problems with static member initialization.

Note: I'm currently writing a fix for this bug, so don't waste time fixing it. I just wanted to create this issue so that I can link to it in the source code.

This code:

struct MyStruct {
    static int weirdvalue;
};
int MyStruct::weirdvalue = 123;

creates these bindings:

extern "C" {
    #[link_name = "\u{1}_ZN8MyStruct10weirdvalueE"]
    pub static mut MyStruct_weirdvalue: ::std::os::raw::c_int;
}
pub const weirdvalue: ::std::os::raw::c_int = 123;

The last line is wrong, there is no global variable just called "weirdvalue", there is only the variable "MyStruct::weirdvalue".

This creates problems with templates, because

template<typename typ>
struct MyStruct {
    static typ weirdvalue;
};
template<typename typ>
typ MyStruct<typ>::weirdvalue = 123;

generates

extern "C" {
    pub static mut weirdvalue: typ;
}

which fails compilation with cannot find type `typ` in this scope

Reproduce the issue with the two C++ examples and inspect the generated Rust bindings shown in the report. Done means static members retain their class-qualified identity and the templated case no longer refers to the out-of-scope typ.
