Add support for UFS2. UFS2 is an enhanced FFS, adding support for 64 bit block pointers, extended attribute storage, and a few other things. This commit does not yet include the code to manipulate the extended storage (for e.g. ACLs), this will be done later. Originally written by Kirk McKusick and Network Associates Laboratories for FreeBSD.

Add support for non-native byteorder FFS, and converting byteorder. Also, be a bit more conservative with the clean flag: don't mark the FS clean when we know there may still be errors (user anserwed 'n' to a question, or fsck says "you must rerun fsck").

In pass 5, check alternate superblocks for consistency with the current in-core master superblock, and fix them up if they're incorrect. Move the code that writes the alternate superblocks if (cvtlevel || doswap) into pass 5 for efficiency. Reviewd by Charles Hannum, and used by me to fix up a curdled file system.

The reconnect algorithm was historically O(n^4). Some years ago I made it O(n^2). Someone helpfully made it O(n^4) again. Today I'm making it O(n). If that's not good enough, I don't know what else to do. B-) Technical details: * The graph traversal in propagate() is modified to be able to start from any point in the tree. To handle certain exceptional cases, it is also modified to work in two passes, marking the tree with a special tag and then changing it to DFOUND. * The reconnect case now modifies the child/sibling pointers and calls propagate() to propagate the connection state starting with the reconnected directory. Pray that you never encounter a file system trashed enough for this to matter.

Write update some old fields when writing the superblock, similar to ffs_oldfscompat_write() in the kernel. Use the old totals when time < old_time (i.e. an old kernel or fsck wrote the filesystem last). When setting the date back on a new kernel, that works out ok, since new kernels always update both fields.
