41d8423f71 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.

e78ea9f724 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.

not know of any software using them, and there is no "published API" for

7a51271b68 Close the disk file descriptor that is RO before trying to open the
new one, and do not fall back to the RO fd.  There was a bug here
in that the RO fd was never closed, if the RDRW open succeeded, but
this code is bogus anyway, and it breaks newfs of floppies, at least
for me, due to "Device busy."  Anything that wants to fall back is
doing something significantly odd that it should have some more complex
code on its end.

a506dcda3d Clean up error reporting in block.c, so that it gives honest error strings
for the sorts of errors we run into[1].  This also gives us room to put in a
vaguely appropriate casts to silence warnings since our compiler doesn't like
when we compare ssize_t to size_t[2].  Add a cast in sblock.c[3] to silence
a warning because of signed vs. size_t hell (again).  Clean up nearby
excessive parenthemutilation[4].

An aside about [4], bde notes that we do not check for a negative value for
the fs bsize.  I'm nto going to do that in every situation we use it, one must
expect a reasonable program to pass down reasonable values.  Some foot shooting
protection I will tolerate, some I will not.  Also he suggests some possible
conditional improvements there, which I may take to heart.

PS: For me at least, this is now WARNS=5 clean...

fe8b86a06d If we don't know where the sblock is (e.g. filling out a blank disk), then
get it from the fs structure.  Really libufs should have interfaces to generate
both what we export, and what we import, based on eachother, and this should
be full of redundant code to make sure everything is right...  But really, we
don't even deal with checksums, so plenty of room to improve.

49b2a6863b 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.

ada981b228 Create a new 32-bit fs_flags word in the superblock. Add code to move
the old 8-bit fs_old_flags to the new location the first time that the
filesystem is mounted by a new kernel. One of the unused flags in
fs_old_flags is used to indicate that the flags have been moved.
Leave the fs_old_flags word intact so that it will work properly if
used on an old kernel.

Change the fs_sblockloc superblock location field to be in units
of bytes instead of in units of filesystem fragments. The old units
did not work properly when the fragment size exceeeded the superblock
size (8192). Update old fs_sblockloc values at the same time that
the flags are moved.

20938dbf84 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.
