Remove regress getdents test, obsoleted by ATF tests

There are ATF tests using rumpkernel to verify getdents:
- tests/fs/hfs/t_pathconvert
- tests/fs/kernfs/t_basic
- tests/fs/vfs/t_union

branches: 1.8.36;
Remove the kernel and ipf tests that have been converted to atf and now
live in the tests subtree.

branches: 1.7.14;
Convert the regress/sys/fs/tmpfs tests to the atf

This change converts all the existing regression tests in
regress/sys/fs/tmpfs to the new framework provided by atf. As a side
effect, this also moves all the tests programs in regress/sys/fs/tmpfs to
tests/fs/tmpfs.

branches: 1.6.8;
Add simple lseek() test on a standard file. Standard it runs on the
/var/log/messages file wich is most likely not interesting but the
regression test can work on every specified filingsystem by passing a file
on that filingsystem to it as argument.

It tests:
- initial position
- seeking absolute position
- seeking end
- seeking negative relative position

more can be added later.

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

OK'ed by my project mentor, William Studenmund (wrstuden@).

test getdents(2). currently fail on nfs.

Add a regression test for mkdir(2) and rmdir(2).

Add missing NetBSD ID tags

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Use a local disktab instead of requiring "floppy288" to be in
"/etc/disktab" as suggested by Simon Burge.

Add a note that the kernel needs FFS Endian Independent support to perform
this test.

Note that this is derived from PR 6706 submitted by Brian Grayson.

FFS regression tests: tests newfs, kernel, fsck_ffs and dump/restore.

FFS regression tests: tests newfs, kernel, fsck_ffs and dump/restore.

Regression test to ensure that (1) newfs_lfs and fsck_lfs agree about
what makes up a good filesystem; and that (2) the kernel and fsck_lfs
also agree. This test, like the 9994 test and like the FFS endianness
test, is not included in the main "make regress".

Add regression tests section for LFS. First regression test is based on
IWAMOTO Toshihiro's test program submitted with PR #9994, modified to
perform the same operations on a control file, presumably held in a
known-working filesystem. Test and control files are compared with "diff"
after the run (assuming that the kernel does not panic, which is really
the main point of the test).

Not included in the parent Makefile's list, as it requires the existence of
an LFS of some size.

Move lfs_cleanerd from /usr/libexec to /libexec. This is to allow putting
the root file system on a LFS volume.

Addresses PR bin/30407. No objections in tech-userlevel@.

Include testing of the roll-forward agent, when recreating the filesystem
partial-segment by partial-segment. Each checkpoint should pass fsck_lfs -n
without errors; the results of fsck_lfs -p on non-checkpoints should also
pass fsck_lfs -n without errors.

Change LFCNWRAP{STOP,GO} to make them more suitable for snapshotting; in
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again. Updated the ckckp
regression test to use the new semantics.

dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4). Fixed a couple
other problems with dump_lfs that manifested themselves during testing.

Allow the user to specify a file size in the ckckp regression test, including
the value zero (filling the filesystem with directories and empty file
inodes).

Be a little more careful about what we copy into the working file when;
this takes care of another class of false positives. Add copyright
assignments.

Regression test improvements:

Move the stop for LFCNWRAPSTOP to the point at which writing at segment 0
is really about to commence, since this is what the test expects (and
incidentally what a snapshotting utility wants as well).

More correctly reconstruct the on-disk state at every checkpoint, rather
than relying on the entire state at the point of wrapping to be accurate
(that is only true the first time we wrap). Add a "make abort" target to
make rerunning the test more convenient when it has failed and we're done
analyzing the failure.

Introduce two fcntl calls that freeze the filesystem right at the point
where segment 0 is being considered for writing. This allows for automated
checkpoint vailidity scanning, and could be used (in conjunction with the
existing LFCNREWIND) for e.g. snapshot dumps as well.

Include a regression test that does such scanning.

When writing the Ifile, loop through the dirty block list three times to
make sure that the checkpoint is always consistent (the first and second
times the Ifile blocks can cross a segment boundary; not so the third time
unless the segments are very small). Discovered by using the aforementioned
regression test.

Various minor LFS improvements:

* Extend the lfs library from fsck_lfs(8) so that it can be used with a
not-yet-existent LFS. Make newfs_lfs(8) use this library, so it can
create LFSs whose Ifile is larger than one segment.
* Make newfs_lfs(8) use strsuftoi64() for its arguments, a la newfs(8).
* Make fsck_lfs(8) respect the "file system is clean" flag.
* Don't let fsck_lfs(8) think it has dirty blocks when invoked with the
-n flag.
