[Libguestfs] [libnbd PATCH 0/2] Optimize h.pread_structured

Add some more safety against a non-compliant server with structured reads, and kill off another useless copy operation for a noticeable speedup when using h.pread_structured. However, I'm still trying to play with code to see if PyObject_GetItem(memoryview, PySlice_New(start, end, NULL)) can get me the same zero-copy python object but in a way that can survive as long as the original object lives, rather than forcing .release() at the end of the callback. Maybe I'll have a patch 3/2 later today.
