- Merge soft-updates journaling from projects/suj/head into head. This
brings in support for an optional intent log which eliminates the need
for background fsck on unclean shutdown.

Back to WARNS=3. The breakage wasn't what I thought it was :(

Increased warnings weren't tested on ARM. Bump warnings back down to
0 until it can be properly tested by those raising the warnings.
Remember: make universe is required when changing the WARNS level.

Build lib/ with WARNS=6 by default.

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

Add a berase() function which uses ioctl(DIOCGDELETE) to erase a slab
of the disk.

Implement cgwrite1(3) function which stored a given cylinder group on disk.

Disconnect getino.3 and remove MLINK I added.

Hook getino.3 up to the build and link it to putino.3.

style.Makefile(5)

Stage 3 of dynamic root support. Make all the libraries needed to run
binaries in /bin and /sbin installed in /lib. Only the versioned files
reside in /lib, the .so symlink continues to live /usr/lib so the
toolchain doesn't need to be modified.

Commit rudimentary libufs manual pages, except for that for
getino(3)/putino(3), inode.c has been reworked in Perforce to the point
where a manual page may not be accurate. Certainly putino(3) has not
even been merged back yet.

These will need a lot of improvement for most applications, but they
document the API enough to get someone on their feet, most likely. The
best documentation still exists in the form of libufs(3) consumers in the
base system.

WARNS ?= 2, so idiocy like 1.12 of type.c doesn't have to happen again.

Add facility to read one, or a string of, cylinger groups.

Nuke dumb error reporting code, people can just use disk::d_error. Unify the
DEBUG and d_error initialisation into an ERROR macro, which can both trace and
set the d_error field. Much a more meaningful thing, I should say.

Add the concept of a per-disk error string, and a function which prints it
along with the errno, if one is set.

No need to explicitly set NOMAN here.

DEBUG is a knob that means something else in FreeBSD, use LIBUFS_DEBUG to
turn on tracing.

Add libufs, a library for dealing with UFS filesystems from userland to
the build. It is here to compartmentalise functionality currently duplicated
in many notable programs in the base system. It currently handles block
reads and writes, as well as reading and writing of the filesystem superblock,
and the reading/lookup of inode data. It supports both UFS and UFS2. I
will be maintaining it, and porting programs to use it, however for now, it
is simply being built as part of world.
