Remove Softdep.

Softdep has been a no-op for some time now, this removes it to get
it out of the way.

Flensing mostly done in Talinn, with some help from krw@

Both phase 1 and phase 5 need the cylinder group meta data, so save those

inodesc.id_entryno holds a file size, so upgrade it from int to u_int64_t;
this fixes handling of very large files on FFS2.
Correct a copy-n-pasto that rendered useless the check for allocated
fragmented that are marked free in the bitmap.
allocdir() returns an inode number, so return an ino_t.
sizeof()*N should be printed with %zu, while direct and indirect block
numbers should be cast to (long long) use %lld

inodesc.id_entryno fix based on a diff from David Vasek <vasek@fido.cz>

Fix '-b' option to work with the superblock locations output by newfs
on 4096-byte sector disks. No-op on 512-byte sector disks.

Adhering to the bedrock idea that ffs will *never* use anything but
512-byte block disk addressing (a.k.a. daddr_t), and believing that
the 'fake' bread()/bwrite() functions should always be using 512-btye
block numbers like their kernel big brothers, nuke the computed
dev_bsize and use DEV_BSIZE for conversions to/from byte offsets.

Spotted and various fixes tested by David Vasek.

Still to fix: scanning for superblocks on 4K disks.

ok otto@

No need to cast constants or simple variables to (daddr_t). Use
(u_int64_t) instead of (daddr_t) when casting a variable in an
expression passed to DL_SETDSIZE().

Change a variable counting open files from daddr_t to int64_t.

ok deraadt@ with the tweak to fix that pesky expression.

final removal of daddr64_t. daddr_t has been 64 bit for a long enough
test period; i think 3 years ago the last bugs fell out.

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

VFS Lite2 Changes

Sync with NetBSD 961019

From Kirk McKusick:
If a directory somehow develops a hole (that is a block pointer
that has a value of zero), fsck would give the filesystem a clean
bill of health, but the kernel would panic when accessing the
directory with the hole. Fsck now checks for holes in directories.
If found in preen mode, fsck fails. In manual mode, it can be
directed to shorten the directory to the beginning of the hole. A
more complete solution would be to allocate a block to fill the
hole. However, this is a lot more work for a `cannot happen' error,
so the extra effort seems unwarranted.
