Make ext2fs_init() call ufs_init(). it was doing the init by itself,
testing for extern done != 0. This bug was hidden by the fact that
ext2fs_init() is called before ffs_init().

7e0aabe421 Remove v_type != DIR check. First, vn_readdir already does 
this check, before calling VOP_READDIR.  Second, vn_readdir
returns a different error even.  Finally, some FS's might
want to write their directories into files that look like
BSD directories and then have ufs_readdir parse them.

* in the write vnode operator, update the appropriate checks for IO_SYNC being
  set in the ioflag to reflect that IO_DSYNC is now inclusive-or'ed into
  IO_SYNC, and require all IO_SYNC bits to be set for operations defined by
  synchronized I/O file integrity completion but not by synchronized I/O data
  integrity completion.

651b44e211 Rework the way kernel include files are installed. In the new method, 
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

091dafd39f Add support for reading/writing FFS in non-native byte order, conditioned 
to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped
when used (as they are acceeded directly in the buffer cache).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.

8c0a9bab00 Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many 
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

76c414a957 Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h: 
- added an "union inode_ext" to struct inode, for the per-fs extentions.
  For now only ext2fs uses it.
- i_din is now an union:
	union {
		struct  dinode ffs_din; /* 128 bytes of the on-disk dinode. */
		struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
	} i_din
  Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
  macro, depending on the time of the inode. ITIMES is used where necessary,
  FFS_ITIMES and EXT2FS_ITIMES in other places.

ebe1c82eda Make the struct lfs 512 bytes long on 32bit machines whose compiler doesn't 
align 32bit integers. Use explicit sized typing at some other places.

XXX This still won't fix lfs for 64bit machines, as we have some
assumptions about sizeof(pointer)=sizeof(u_int32_t) in here, and (if I
looked right) a misaligned u_int64_t. The right fix (to cite cgd) will
be to seperate on-disk-representation from in-core, but I don't have
the time (at the moment) to do this.

f6e4567c57 cast int64_t-sized types to "long long" before printing them with %qd. 
gcc thinks that the 'q' modifier describes a "long long", and so -Wformat
whines when printing with 'q' on the alpha, since int64_t-sized types are
done with variations on "long" rather than "long long".

53fccab940 Fix vop_link, vop_symlink, and vop_remove semantics in several ways: 
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
