Moved code initialising fsg_common structure to fsg_common_init() function which is called from fsg_bind(). Moreover, changed reference counting mechanism: fsg_common has a reference counter which counts how many fsg_dev structures uses it. When this reaches zero fsg_common_release() is run which unregisters LUN devices and frees memory. fsg_common_init() takes pointer to fsg_common structure as an argument. If it is NULL function allocates storage otherwise uses pointed to memory (handy if fsg_common is a field of another structure or a static variable). fsg_common_release() will free storage only if free_storage_on_release is set -- it is initialised by fsg_common_init(): set if allocation was done, unset otherwise (one may overwrite it of course).
