1.1.1.1

@Import ATF 0.5

Changes in this release:

* Clauses 3 and 4 of the BSD license used by the project were dropped.
  All the code is now under a 2-clause BSD license compatible with the
  GNU General Public License (GPL).

* Added a C-only binding so that binary test programs do not need to be
  tied to C++ at all.  This binding is now known as the atf-c library.

* Renamed the C++ binding to atf-c++ for consistency with the new atf-c.

* Renamed the POSIX shell binding to atf-sh for consistency with the new
  atf-c and atf-c++.

* Added a -w flag to test programs through which it is possible to specify
  the work directory to be used.  This was possible in prior releases by
  defining the workdir configuration variable (-v workdir=...), but was a
  conceptually incorrect mechanism.

* Test programs now preserve the execution order of test cases when they
  are given in the command line.  Even those mentioned more than once are
  executed multiple times to comply with the user's requests.
