    libsoup/soup-session.c: Don't Hardcode Paths on Windows
    
    On Windows, use g_win32_get_package_installation_directory_of_module()
    and g_build_filename() to acquire the localedir to find the translations
    on Windows, instead of relying on the LOCALEDIR which is hardcoded at
    compile time, so that the libsoup DLL can be relocated on Windows with its
    translations.  Therefore, we define a simple DllMain() which is used to
    acquire the proper HMODULE for the purpose.
