Rework pflowioctl() lock dances. Release netlock and take `sc_lock' rwlock(9) just in the beginning of pflowioctl() and do corresponding operations in the end. Use `sc_lock' to protect `sc_dying'. We need to release netlock not only to keep locks order with `sc_lock' rwlock(9), but also because pflowioctl() calls some operations like socreate() or soclose() on udp(4) socket. Current implementation has many relocking places which breaks atomicy, so merge them into one. The `sc_lock' rwlock(9) is taken during all pflowioctl() call, so `sc_dying' atomicy is not broken. Not the ideal solution, but better then we have now. Tested by Hrvoje Popovski. Discussed with and ok from sashan |

Make `fuse_rd_filtops' mpsafe. Introduce `fd_lock' rwlock(9) and use it for `fd_fbufs_in' fuse buffers queue and `fd_rklist' knotes list protection. Tested by Rafael Sadowski. Discussed with and ok from bluhm |
