Fix "frame variable" to show all variables defined in functions and any contained lexical blocks, even if they are static variables. 

For code like:

int g_global = 234;
int g_static = 345;
int main(int argc, char **argv)
{                     
    int a = 22333;
    static int g_int = 123;
    return g_global + g_static + g_int + a;
}


If we stop at the "return" statement, we expect to see "argc", "argv", "a" and "g_int" when we type "frame variable" since "g_int" is a locally defined static variable, but we don't expect to see "g_global" or "g_static" unless we add the -g option to "frame variable".
