Log message:
Update ATF to 0.20.

This change upgrades devel/atf to 0.20 and removes devel/atf-libs.  The
upstream atf distfile has dropped the code for the deprecated tools so
it makes little sense to keep the two packages any longer.

As a result of this, the devel/atf package is now much simplified as
there is no need for a Makefile.common any longer and matches exactly
what upstream ships.

Changes in version 0.20
***********************

Experimental version released on February 7th, 2014.

This is the first release without the code for the deprecated tools.  If
you require such code, please fetch a copy of the 0.19 release and extract
the 'tools' directory for your own consumption.

* Removed the deprecated tools.  This includes atf-config, atf-report,
  atf-run and atf-version.

Changes in version 0.19
***********************

Experimental version released on February 7th, 2014.

This is the last release to bundle the code for the deprecated tools.
The next release will drop their code and will stop worrying about
backwards compatibility between the ATF libraries and what the old tools
may or may not support.

If you still require the old tools for some reason, grab a copy of the
'tools' directory now.  The code in this directory is standalone and
does not depend on any internal details of atf-c++ any longer.

* Various fixes and improvements to support running as part of the FreeBSD
  test suite.

* Project hosting moved from Google Code (as a subproject of Kyua) to
  GitHub (as a first-class project).  The main reason for the change is
  the suppression of binary downloads in Google Code on Jan 15th, 2014.
  See https://github.com/jmmv/atf/

* Removed builtin help from atf-sh(1) and atf-check(1) for simplicity
  reasons.  In other words, their -h option is gone.

* Moved the code of the deprecated tools into a 'tools' directory and
  completely decoupled their code from the internals of atf-c++.  The
  reason for this is to painlessly allow a third-party to maintain a
  copy of these tools after we delete them because upcoming changes to
  atf-c++ would break the stale tools.

Log message:
Update atf and atf-libs to 0.17:

* Added the atf_utils_cat_file, atf_utils_compare_file,
  atf_utils_copy_file, atf_utils_create_file, atf_utils_file_exists,
  atf_utils_fork, atf_utils_grep_file, atf_utils_grep_string,
  atf_utils_readline, atf_utils_redirect and atf_utils_wait utility
  functions to atf-c-api.  Documented the already-public
  atf_utils_free_charpp function.

* Added the cat_file, compare_file, copy_file, create_file, file_exists,
  fork, grep_collection, grep_file, grep_string, redirect and wait
  functions to the atf::utils namespace of atf-c++-api.  These are
  wrappers around the same functions added to the atf-c-api library.

* Added the ATF_CHECK_MATCH, ATF_CHECK_MATCH_MSG, ATF_REQUIRE_MATCH and
  ATF_REQUIRE_MATCH_MSG macros to atf-c to simplify the validation of a
  string against a regular expression.

* Miscellaneous fixes for manpage typos and compilation problems with
  clang.

* Added caching of the results of those configure tests that rely on
  executing a test program.  This should help crossbuild systems by
  providing a mechanism to pre-specify what the results should be.

* PR bin/45690: Make atf-report convert any non-printable characters to
  a plain-text representation (matching their corresponding hexadecimal
  entities) in XML output files.  This is to prevent the output of test
  cases from breaking xsltproc later.

Log message:
Update to ATF 0.16:

Experimental version released on July 10th, 2012.

* Added a --enable-tools flag to configure to request the build of the
  deprecated ATF tools, whose build is now disabled by default.  In order
  to continue running tests, you should migrate to Kyua instead of enabling
  the build of the deprecated tools.  The kyua-atf-compat package provides
  transitional compatibility versions of atf-run and atf-report built on
  top of Kyua.

* Tweaked the ATF_TEST_CASE macro of atf-c++ so that the compiler can
  detect defined but unused test cases.

* PR bin/45859: Fixed some XSLT bugs that resulted in the tc-time and
  tp-time XML tags leaking into the generated HTML file.  Also improved
  the CSS file slightly to correct alignment and color issues with the
  timestamps column.

* Optimized atf-c++/macros.hpp so that GNU G++ consumes less memory during
  compilation with GNU G++.

* Flipped the default to building shared libraries for atf-c and atf-c++,
  and started versioning them.  As a side-effect, this removes the
  --enable-unstable-shared flag from configure that appears to not work any
  more (under NetBSD).  Additionally, some distributions require the use of
  shared libraries for proper dependency tracking (e.g. Fedora), so it is
  better if we do the right versioning upstream.

* Project hosting moved from an adhoc solution (custom web site and
  Monotone repository) to Google Code (standard wiki and Git).  ATF now
  lives in a subcomponent of the Kyua project.
