r267176:

 Add the *_TESTS_SH_SED_* functionality to atf.test.mk.

 This exists already in plain.test.mk and tap.test.mk and should have been
 added to atf.test.mk too when the feature was first introduced.

 (It is probably time to address the related TODOs but I will do that
 separately.)

r267181:

 Move atf-sh from /usr/bin/ to /usr/libexec/

 In r266650, we made libatf-c and libatf-c++ private libraries so that no
 components outside of the source tree could unintendedly depend on them.

 This change does the same for the "atf-sh library" by moving the atf-sh
 interpreter from its public location in /usr/bin/ to the private location
 in /usr/libexec/.  Our build system will ensure that our own test programs
 use the right binary, but users won't be able to depend on atf-sh by
 "mistake".

 Committing this now to ride the UPDATING notice added with r267172 today.

r268445:

 Fix atf-sh's integration_test

 With the move of atf-sh into /usr/libexec in r267181, some of the
 tests in the integration_test program broke because they could not
 execute atf-sh from the path any longer.

 This slipped through because I do have a local atf installation in
 my home directory that appears in my path, hence the tests could
 still execute my own version.

 Fix this by forcing /usr/libexec to appear at the beginning of the
 path when attempting to execute atf-sh.

 To make upgrading easy (and to avoid an unnecessary entry in UPDATING),
 make integration_test depend on the Makefile so that a rebuild of the
 shell script is triggered.  This requires a hack in the *.test.mk files
 to ensure the Makefile is not treated as a source to the generated
 program.  Ugly, I know, but I don't have a better way of doing this at
 the moment.  Will think of one once I address the TODO in the *.test.mk
 files that suggests generalizing the file generation functionality.

r266650:

  Change libatf-c and libatf-c++ to be private libraries.

  We should not be leaking these interfaces to the outside world given
  that it's much easier for third-party components to use the devel/atf
  package from ports.

  As a side-effect, we can also drop the ATF pkgconfig and aclocal files
  from the base system.  Nothing in the base system needs these, and it
  was quite ugly to have to get them installed only so that a few ports
  could build.  The offending ports have been fixed to depend on
  devel/atf explicitly.

r267172:

  Homogenize libatf-* version numbers with upstream.

  The libatf-* major version numbers in FreeBSD were one version ahead of
  upstream because, when atf was first imported into FreeBSD, the upstream
  numbers were not respected.  This is just confusing and bound to cause
  problems down the road.

  Fix this by taking advantage of the fact that libatf-* are now private
  and that atf is not yet built by default.  However, and unfortunately, a
  clean build is needed for tests to continue working once "make
  delete-old-libs" has been run; hence the note in UPDATING.

df68f62846 The origin_subst_one() function limits the length of the string to
PATH_MAX after the token substitution.  This is wrong, because
origin_subst_one() performs the substitution on the whole rpath and
similar strings, which contain several pathes separated by colon.  As
result, long (but correct) rpath consisting of many path elements is
rejected by the function.

Correct the problem by rewriting the origin_subst_one() to perform two
passes, first pass to calculate the number of substitutions to be
performed, and second pass to generate the resulting string.  Second
pass allocates the memory for the result based on the count from the
first pass, without enforcing a limit.
