Include Peter Wemm's renaming and restructuring
Remove #ifdefs for FreeBSD 2.c Change from lkm to kld correct type of `flags' in calls to set_drive_state. set_drive_parms: handle anonymous drives correctly (remove them) drive VOP functions: use the PID of the original opener to fool the lock manager. open_drive: be quiet about failures (they're normal when scanning the partitions). close_drive: lock drive before closing. remove_drive: lock drive before deallocating. read_drive_label: set drive up when all is OK check_drive: Complete rewrite. Offload most of the code to the new vinum_scandisk format_config: use snprintf and %qd options to make much less emetic. Remove old supporting functions. vinum_scandisk: Moved here from vinum.c Almost complete rewrite, incorporating much of what was check_drive. We still don't have a general way to find the drives on a system, so get the user to supply the names via the `read' command. For each device, try each possible compatibility slice name (there's a danger of finding both /dev/da1h and /dev/da0s1h otherwise). Sort the partitions found in reverse order of last update time and read them in, setting the `update' parameter to parse_config and descendents. save_config: rename to daemon_save_config, since the function is now called by the daemon. Create a new function save_config which queues the request with the daemon. daemon_save_config: some mods to allow for the unfamiliar environment.
