arogue7, xrogue: improve the handling of the arguments to fuses. fuse() now expects a pointer as the argument to a fuse function. If this is one of the functions that takes int, fuse() follows the pointer and stores that value in the f_list slot, in the integer field of the argument union. When the fuse goes off, do_fuses() recognizes the function and passes it the integer field instead of the pointer. This has the disadvantage of hard-coding the functions that require int in daemon.c, but since the int is copied into f_list, it no longer has to be in static or global memory, which simplifies several files.
