[Crash-utility] crash version 4.0-3.18 is available

[Dave Anderson]

- Enhancement to the "mod" command to expand the number of section
  arguments to the internal "add-symbol-file" command issued to gdb to
  load the debug data for module objects.  On most architectures,  this
  allows the usage of the command construct "p [module-symbol-name]" to
  print out the module data structure in the same way that is done for
  kernel proper data structure names.  (castor.fu at 3pardata.com)

- Two enhancements to significantly speed up the initialization of
  crash sessions when running against multi-gigabyte xen kernels or
  xendumps.  The cache of mfn-to-phys_to_machine_mapping page has been
  changed from a single-mfn-to-phys_to_machine_mapping page format to
  storing a contiguous-range-of-mfns-to-phys_to_machine_mapping format.
  This benefit is primarily seen during the "gathering module symbol
  data" phase.  The second change simply increases the size of the
  pfn-to-xendump-page-offset cache.  (anderson at redhat.com)

- Fix for a segmentation violation during the "gathering task table
  data" phase of initialization if the thread_info structure of the
  runqueue-advertised active task has been freed.  This has only ever
  been seen in a xendump created by "xm dump-core -L [guest-domain]".

- Cosmetic fix to prepend newlines to messages that happen to be
  generated during any of the "please wait" segments of initialization.

- Addressed several compiler warnings when using -D_FORTIFY_SOURCE=2.
  Some are in gdb code that is never exercised, others were legitimate
  but would require impossible code paths, but one of them could
  result in runaway "help -t" output if the kernel was built without
  IKCONFIG.  (bwalle at suse.de)

- Fix for the s390x "bt -f" command option, which was displaying the
  stack as a sequence of 32-bit words which were dumped "backwards",
  i.e., at the wrong offset.  (krader at us.ibm.com)
