Add a new lfs header file: lfs_accessors.h.

This contains all the accessor functions and macros out of lfs.h.
Add an include of lfs_accessors.h after all uses of lfs.h... except
for code that wants to define its own struct lfs-alike that the
accessors are supposed to play along with. For these, set STRUCT_LFS
and include lfs_accessors.h after the necessary structure has been
defined, so that lfs_accessors.h can emit functions in terms of it.

More lfs superblock accessors.
(This changes the rest of the code over; all the accessors were
already added.)

The difference between this commit and the previous one is arbitrary,
but the previous one passed the regression tests on its own so I'm
keeping it separate to help with any bisections that might be needed
in the future.

Switch to accessor functions for elements of the LFS on-disk
superblock. This will allow switching between 32/64 bit forms on the
fly; it will also allow handling LFS_EI reasonably tidily. (That
currently doesn't work on the superblock.)

It also gets rid of cpp abuse in the form of fake structure member
macros.

Also, instead of doing sleep/wakeup on &lfs_avail and &lfs_nextseg
inside the on-disk superblock, add extra elements to the in-memory
struct lfs for this. (XXX: these should be changed to condvars, but
not right now)

XXX: this migrates a structure needed by the lfs code in libsa (struct
salfs) into lfs.h, where it doesn't belong, but for the time being
this is necessary in order to allow the accessors (and the various
lfs macros and other goop that relies on them) to compile.

Cleanups and hacks to make lfs userland stuff build:
   - lfs_cksum.c doesn't actually need ulfs_inode.h any more.
   - neither does lfs_itimes.c.
   - add hacks to fsck_lfs to make it compile.
   - add hacks to newfs_lfs to make it compile.
   - fix warning in ulfs_quota.c when quotas are fully disabled
     (as I guess is happening with the rumpity version)

XXX: This commit adds -I${NETBSDSRCDIR}/sys to the Makefiles for
XXX: fsck_lfs, newfs_lfs, and lfs_cleanerd. This needs to be cleaned
XXX: up ASAP; but I consider this less problematic in the short term

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.)

Merge the short-lived perseant-lfsv2 branch into the trunk.

Kernels and tools understand both v1 and v2 filesystems; newfs_lfs
generates v2 by default.  Changes for the v2 layout include:

- Segments of non-PO2 size and arbitrary block offset, so these can be
  matched to convenient physical characteristics of the partition (e.g.,
  stripe or track size and offset).

- Address by fragment instead of by disk sector, paving the way for
  non-512-byte-sector devices.  In theory fragments can be as large
  as you like, though in reality they must be smaller than MAXBSIZE in size.

- Use serial number and filesystem identifier to ensure that roll-forward
  doesn't get old data and think it's new.  Roll-forward is enabled for
  v2 filesystems, though not for v1 filesystems by default.

- The inode free list is now a tailq, paving the way for undelete (undelete
  is not yet implemented, but can be without further non-backwards-compatible
  changes to disk structures).

- Inode atime information is kept in the Ifile, instead of on the inode;
  that is, the inode is never written *just* because atime was changed.
  Because of this the inodes remain near the file data on the disk, rather
  than wandering all over as the disk is read repeatedly.  This speeds up
  repeated reads by a small but noticeable amount.

Other changes of note include:

- The ifile written by newfs_lfs can now be of arbitrary length, it is no
  longer restricted to a single indirect block.

- Fixed an old bug where ctime was changed every time a vnode was created.
  I need to look more closely to make sure that the times are only updated
  during write(2) and friends, not after-the-fact during a segment write,
  and certainly not by the cleaner.

Change disk addressing unit to be the fragment, instead of the disk sector.
All quantities in the superblock, inodes, indirect blocks, etc. refer now
to this abstract unit (called "fsb" as it is in FFS) instead of disk sectors;
as a consequence segment summary blocks have to be multiples of a fragment in
size.  In v1 filesystems, compatibility code ensures that 1 fsb == 1 sector,
regardless of fragment size.

Fragments can now range in size between 512 and 32k; in the event that
LFS_LABELPAD (8k) is smaller than the disk address unit size, an extra
proto-superblock is kept at 8k from the beginning of the disk, to be used
*only* to locate the real superblocks.  (Not all of the userland knows about
this yet.)

Almost all of this was done not by me, but by joff.

Import of what I've been calling "LFSv2", that is, LFS with some features
added that require changes to the on-disk data structures.  These include:

- 64-bit time in everything but inodes
- User-specified segment offset, and segment size no longer
  restricted to PO2.
- Serial number on segment summaries in addition to timestamp, and
  a new volume identifier, to make roll-forward feasible without
  fear of finding old data and thinking it was new.

Although I think this version works at least as well as what's on the trunk,
we're not done yet; hence this commit is going in on a branch and not on
the trunk.  Enhancements that are not here yet include fragment addressing,
like FFS does, instead of block addressing.

Various bug-fixes to LFS, to wit:


Kernel:

* Add runtime quantity lfs_ravail, the number of disk-blocks reserved
  for writing.  Writes to the filesystem first reserve a maximum amount
  of blocks before their write is allowed to proceed; after the blocks
  are allocated the reserved total is reduced by a corresponding amount.

  If the lfs_reserve function cannot immediately reserve the requested
  number of blocks, the inode is unlocked, and the thread sleeps until
  the cleaner has made enough space available for the blocks to be
  reserved.  In this way large files can be written to the filesystem
  (or, smaller files can be written to a nearly-full but thoroughly
  clean filesystem) and the cleaner can still function properly.

* Remove explicit switching on dlfs_minfreeseg from the kernel code; it
  is now merely a fs-creation parameter used to compute dlfs_avail and
  dlfs_bfree (and used by fsck_lfs(8) to check their accuracy).  Its
  former role is better assumed by a properly computed dlfs_avail.

* Bounds-check inode numbers submitted through lfs_bmapv and lfs_markv.
  This prevents a panic, but, if the cleaner is feeding the filesystem
  the wrong data, you are still in a world of hurt.

* Cleanup: remove explicit references of DEV_BSIZE in favor of
  btodb()/dbtob().

lfs_cleanerd:

* Make -n mean "send N segments' blocks through a single call to
  lfs_markv".  Previously it had meant "clean N segments though N calls
  to lfs_markv, before looking again to see if more need to be cleaned".
  The new behavior gives better packing of direct data on disk with as
  little metadata as possible, largely alleviating the problem that the
  cleaner can consume more disk through inefficient use of metadata than
  it frees by moving dirty data away from clean "holes" to produce
  entirely clean segments.

* Make -b mean "read as many segments as necessary to write N segments
  of dirty data back to disk", rather than its former meaning of "read
  as many segments as necessary to free N segments worth of space".  The
  new meaning, combined with the new -n behavior described above,
  further aids in cleaning storage efficiency as entire segments can be
  written at once, using as few blocks as possible for segment summaries
  and inode blocks.

* Make the cleaner take note of segments which could not be cleaned due
  to error, and not attempt to clean them until they are entirely free
  of dirty blocks.  This prevents the case in which a cleanerd running
  with -n 1 and without -b (formerly the default) would spin trying
  repeatedly to clean a corrupt segment, while the remaining space
  filled and deadlocked the filesystem.

* Update the lfs_cleanerd manual page to describe all the options,
  including the changes mentioned here (in particular, the -b and -n
  flags were previously undocumented).

fsck_lfs:

* Check, and optionally fix, lfs_avail (to an exact figure) and
  lfs_bfree (within a margin of error) in pass 5.

newfs_lfs:

* Reduce the default dlfs_minfreeseg to 1/20 of the total segments.

* Add a warning if the sgs disklabel field is 16 (the default for FFS'
  cpg, but not usually desirable for LFS' sgs: 5--8 is a better range).

* Change the calculation of lfs_avail and lfs_bfree, corresponding to
  the kernel changes mentioned above.

mount_lfs:

* Add -N and -b options to pass corresponding -n and -b options to
  lfs_cleanerd.

* Default to calling lfs_cleanerd with "-b -n 4".


[All of these changes were largely tested in the 1.5 branch, with the
idea that they (along with previous un-pulled-up work) could be applied
to the branch while it was still in ALPHA2; however my test system has
experienced corruption on another filesystem (/dev/console has gone
missing :^), and, while I believe this unrelated to the LFS changes, I
cannot with good conscience request that the changes be pulled up.]

fsck_lfs can now write to the filesystem, allowing it to correct most
(though still not all) errors in a damaged lfs.  Segment byte accounting
is corrected in pass 5.  "fsck_lfs -p" will do a partial roll-forward,
verifying the checkpoint from the newer superblock.  fscknames[] is
updated so that fsck knows about fsck_lfs.
