96cec1d54e Defensive programming when reading inodes in getino().
Specifically check for out-of-range inodes, and whether
return-value pointers are NULL.

Followup to r313780.  Also prefix ext2's and nandfs's versions with

260ba0bff1 lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

a574495410 - 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.

7284e7e47f 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.

9c7ad0f5fd Fill out (zero) and fill in (when doing getino()) the minimum and maximum
inodes in our inoblock (disk->d_ino{min,max}) appropriately.

1c27521e29 In getino, have our DEBUG message in the unhandled case mention that it
does not know what sort of UFS filesystem this is.

Add some DEBUG(NULL)'s to function entry points.

e7f13daa73 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.
