Fixes review comments 2. Increase QEMU_PLUGIN_VERSION to 1 for compat QEMU_PLUGIN_VERSION 0 3. Revise the loader to support for version 0 and 1 4. By export function qemu_plugin_initialize in plugin, and call it in loader= , so we have no need call it in every plugin. And also provide a standard implem= entation, anyway, use can also override it. Add this feature on msys2/mingw by using glib provided cross-platform dlsym f= unctional.
