Initial checkin of fsck_lfs. This version cannot do any repair (-p flag does nothing, and one of -p or -n is required) but can be useful as a diagnostic tool.

Various improvements to fsck_lfs, to wit: * Add lfs_balloc capability to the lfs library. * Extend the Ifile if we run out of free inodes when creating lost+found. * Don't roll forward if we have allocated a lost+found, to avoid conflicts when adding new files in roll-forward. * Make some messages slightly more verbose (e.g. include inode number, and use pwarn() instead of printf() so the messages include the device name when preening). * Change superblock detection/avoidance to use the offset table in the primary superblock, rather than looking at the contents. * Be more verbose about various operations when passed the -d flag, especially roll-forward. * Be more careful about dirops during roll forward, since the cleaner can sometimes write blocks from dirop vnodes. Detect and avoid this problem. * Always check the free list, even if given -i; if we're going to write it we have to check it first. * Mark inodes dirty when blocks are found during roll forward, so the inodes are written with the new block locations. * Update size of inodes if blocks beyond EOF are found during roll forward. * Fix segment accounting for blocks and inodes found during roll forward. * Report statistics on roll forward: how many new/deleted/moved files and how many updated blocks (or "nothing new"). * Don't care if the device being checked is really a device, if we have been passed the -f flag (to facilitate automated testing). * When writing to the disk, use the current time in the segment headers rathern than time 0. * When passed the -i flag, locate the partial segment containing the Ifile inode and use that to calculate lfs_offset, lfs_curseg, lfs_nextseg. (Again for automated testing.)
