Delete support for FFS filesystems before the in-inode symlink
optimization. As observed by ali_farzanrad(at)riseup.net, support
for these was broken in the 5.5 release in early 2014 by the time_t
changes. No one noticed before now, so clearly this isn't something
we need to continue to support; rejecting in ffs_validate() is an
improvement.

Also: simplify DIRSIZ(), drop OLDDIRFMT and NEWDIRFMT, tests of
fs_maxsymlinklen against zero, #ifdef tests of FS_44INODEFMT, and
remove support for newfs -O0, last used in 2016.

Add DIR_ROUNDUP define, from Kirk McKusick

Rewrite DIRECTSIZ macro using offsetof. As a bonus it elimitanes casting
pointer to int.

Remove remaining whiteout tentacles; OK deraadt@ miod@ weingart@

add ian dowse's dirhash code from freebsd.
by building a hash table for large directories, lookups and deletions
become about constant time. this is an excellent improvement for dirs with
10k or more files.
some more cleanup to come, but the code works.

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

branches: 1.7.2;
Yet another useless indentation fix (I don't like 'M' in my cvs updates).

Integrate new ext2fs, reverting ufs support for the old one.

Moving some things around; struct inode still ends up bigger, though.
This should, hopefully, be the last UFS changes required.

ufs_dirops only needed when compiling with _KERNEL

ufs changes: add the notion of directory operators.

gnu/ext2fs: add the second extended filesystem.

Note that I'm commiting this now for the sake of the ufs changes; ext2fs
is not yet fully integrated into the system.
