DMTCP-2.5.2 released

• All fixes in Release DMTCP-2.4.9 are incorporated in this release.
• An incompatibility of DMTCP with Open MPI 1.10 when using orterun (mpirun)
  was discovered. This does not affect recent versions, such as Open MPI 2.x.
• In some rare cases, open files were not properly restored due to
  a use-after-free bug. This is now fixed.
• In some rare cases, one process had created a SysV shared memory object,
  and a different process was assigned to restore it on restart. This
  was not handled correctly, and is now fixed.
• Correctly restore CPU affinities of threads
• Virtualized SysV shared memory keys to avoid race condition on restart
• Fixed logic for checking if relative path to file was a duplicate
  of another existing path
• The NSCD area for name service caching daemon was not handled correctly
  in CentOS 6.8 and later correctly. Fixed now.
• The Linux sched.h include file for scheduling of cores was added to
  satisfy some older Linux distros that needed it for compiling DMTCP.
• Fixed a regression in which --enable-debug (for verbose debug logs)
  was not being properly written.
• The DMTCP coordinator was displaying a spurious warning, "Failed to find
  coordinator IP address", because it did not check for a canoncial hostname.
  A related issue prevented DMTCP from working properly on some
  SUSE/openSUSE distros.
