A first-cut test to ensure that files are well-aligned on filesystems
with stripe geometry.
Several sizes of stripe units are mkfs'd, and then files are written
and fallocated in various multiples of those stripe sizes.
Each file is checked to ensure that the first block is
stripe-aligned.
(Ideally, for any fragmented files, we should ensure that each
fragment start is well-aligned, but this does not do that yet)
(slightly unrelated: don't send scratch mkfs output to /dev/null,
we'd like to see mkfs output and direct it to $seq.full - this
more or less matches _scratch_mkfs_xfs behavior and doesn't
break any tests that I can see)

When selinux is on, ls -l gives us a "." to indicate selinux
attrs, which breaks some tests:
=== Test minimal ACE ===
Setup file
--rwxrw-r-- id1 id2 file1
+-rwxrw-r--. id1 id2 file1
so make an _ls_l helper to filter that out.

Currently the xfstest builds do not have any automatic dependency
calculations. It relies on a separate make depend run to build or
update dependency information. It also relies on an external
makedepend binary. If that binary does not exist, the dependencies
do not get calculated.
To remove the dependency on makedepend, gcc can be used instead as
it has a command to generate dependency information. This patch
changes the dependency rule building to use gcc.
In case anyone uses an old (several years) gcc compiler or a
compiler that doesn't support gcc compatible dependency generation,
a new configure check is added to turn off dependency checking so
builds can still be done.
To use the dependencies automatically, we need to use a special
include makefile directive to include the build dependencies into
the current makefile. Essentially once the dependencies are
calculated, they can be included into the makefile and make will
recalculate the build dependencies automatically based on that
information.
Hence we get a build that automatically calculates and keeps
dependencies up to date without dependence on any external tools.

The local m4 configuration has not been built in a long time.
Trying to rebuild it results in failures with dmapi library
detection and libxfs.h detection macros. Fix the errors and rebuild
it.
Note: the new format for the aclocal.m4 file uses m4_include
directives which means it is much smaller than before and won't
need updating unless we include new m4 macro files.

Tests 018, 081 and 082 read the contents of the log and assume that the
contents will always be the same. They are trying to ensure that the
contents of the log don't change for a given fixed load.
This has several problems - high level changes to the filesystem and
VFS code can change the order and contents of the log. Changes to
the way we sync the filesystem will change the contents of the log.
background writeback occurring in the middle of the test will change
the contents of the log by allowing the tail to move. Even changes
to the default mkfs parameters can break them!
The tests also assume that unmount leaves a dirty log behind. We've
fixed lots of problems in sync and the unmount paths over recent
times, so now a clean unmount leaves a clean log behind. That is,
there is nothing left in the log print output for these tests to
check. IOWs, major surgery is required for these tests to be
returned to their former break-when-something-changes behaviour.
However, these tests are a maintenance nightmare. They spend more
time broken and failing than they do passing, and then it's not long
before they get broken again. They have to cover all sorts of
different permutations of log configurations and that will continue
to grow and increase the complexity of making these tests continue
to work. And to top it all off, I can't remember a bug actually ever
being found by these tests. Hence I think we should just stop using
them altogether.
So this patch deprecates 018, 081 and 082 rather than fixes them.
It introduces a "deprecated" test group and puts them in it. That
means the tests can still be run on older systems where they may
have some use, but will not be run automatically any more, nor
will any attempt be made to keep them up to date or working.

Using signal() to set up signal handlers doesn't always do what you
want. A recent upgrade made test 208 fail because wait() was not
getting interrupted by a SIGALRM. Tracing showed that signal() was
being converted to a sigaction(SA_RESTART) handler, which allows
syscalls that return ERESTARTSYS to immediately restart without
returning EINTR to the calling process. The kernel code returns
ERESTARTSYS to signal interruptions while in wait().
Replace the use of signal with sigaction() to ensure that the
SA_RESTART flag is not set and the EINTR is delivered to the process
sitting in wait(). This makes test 208 terminate at 200s again.

Remove explicit target-per-file rules in the subdirectories being
built and replace them with target based rules using the buildrules
hooks for doing this. This results in the makefiles being simpler,
smaller and more consistent. It does mean that all binaries are
linked against the common set of libraries but this does not cause
any harm.

We don't need to see every compiler command line for every file that
is compiled. This makes it hard to see warnings and errors during
compile. For progress notification, we really only need to see the
directory/file being operated on.
Turn down the verbosity of output by suppressing various make output
and provide better overall visibility of which directory is being
operated on, what the operation is and what is being done to the
files by the build/clean process.
This patch only addresses the top level makefile and build rules; it
does not clean up the subdirectories - these will be addressed by a
followup patch. It also does not touch the dmapi section of the
xfstests build system.
The old style verbose builds can still be run via "make V=1 ..."
