Log Message:
Update to 0.15:

Experimental version released on January 16th, 2012.

* Respect stdin in atf-check.  The previous release silenced stdin for any
  processes spawned by atf, not only test programs, which caused breakage
  in tests that pipe data through atf-check.

* Performance improvements to atf-sh.

* Enabled detection of unused parameters and variables in the code and
  fixed all warnings.

* Changed the behavior of "developer mode".  Compiler warnings are now
  enabled unconditionally regardless of whether we are in developer mode or
  not; developer mode is now only used to perform strict warning checks and
  to enable assertions.  Additionally, developer mode is now only
  automatically enabled when building from the repository, not for formal
  releases.

* Added new Autoconf M4 macros (ATF_ARG_WITH, ATF_CHECK_C and
  ATF_CHECK_CXX) to provide a consistent way of defining a --with-arg flag
  in configure scripts and detecting the presence of any of the ATF
  bindings.  Note that ATF_CHECK_SH was already introduced in 0.14, but it
  has now been modified to also honor --with-atf if instantiated.

* Added timing support to atf-run / atf-report.

* Added support for a 'require.memory' property, to specify the minimum
  amount of physical memory needed by the test case to yield valid results.

* PR bin/45690: Force an ISO-8859-1 encoding in the XML files generated by
  atf-report so that invalid data in the output of test cases does not
  mangle our report.
