Update to 1.13.0 from new upstream.

  New in CppUnit 1.13.0:
  ----------------------

* Portability:
  - Added support for macro CPPUNIT_UNIQUE_COUNTER to config-*.h. It
    should expands to a unique number per translation unit. Default
    to __LINE__ if not defined. Use __COUNTER__ on MSVS 7.0+.
    (Bug #2031696)

* Compilation

  - destructor of Message causes segfault when testing (rhbz#641350)

  - use correct CPPUNIT_VERSION value (sf#2983798)

  - allow -Werror builds
    (various Libreoffice patches)

  - finite in "ieeefp.h" instead of math.h on Solaris (sf#2912590)

  - Fixed compilation issue with Microsoft Visual Studio.Net 2005/2008 and
    added Visual Studio 2005/2010  projects (.vcproj/.vcxproj)

  - Changes to build without warnings using gcc -Wall -W -ansi
    (patch #1898225 contributed by dpkatz)

  - Libraries flags such as "-ldl" are now in LDADD instead of LIBADD_DL
    ( patch #2807259 contributed by Jan Echternach).

  - Fixed detection of cxxabi.h with gcc 4.3 in configure (bug #2796543).

  - made TestCaseDecorator copy c'tor and operator= private (fdo#51317)

* Documentation

  - Updated several false documentation entries (sf#2185407, sf#2186611)

* Test Plug-in Runner:
  - fixed memory leak in TestPlugInRunnerDlg (#1721408)
