This patch implements a .from_buffer(source, offset=0) class method from ctypes types. 'source' must expose a writeable buffer interface; the created ctypes instance will share the internal buffer of the source object; also it holds a reference to the source object to keep it alive. The usual problems with the buffer interface are not hidden. Open question: Should there be an additional 'copy_from_buffer' class method that accepts read-only buffer interface (as an alternative, an optional 'copy=False' parameter could be introduced)?
