[Crash-utility] crash version 4.0-3.8 is available

[Dave Anderson]

- Tentatively scheduled as base version for RHEL4-U5.

- Fix for the "irq" command when run on 2.6.17 and later kernels, which
  replaced the hw_interrupt_type structure with the irq_chip structure.
  Without the patch, the command would fail with the error message
  "irq: invalid structure member offset: irq_desc_t_handler".

- Phased in the first stage of support for the use of dwarf CFI data to
  produce accurate x86_64 back traces, and to eventually improve the
  reliability of x86 back traces.  The code is very much still under
  development, and is not turned on as of yet; for x86_64 only, its
  usage can be toggled on and off with the set command, by entering
  "set unwind on" or "set unwind off".  It will only work if dwarf CFI
  information exists in the kernel memory, or if the vmlinux file
  contains an .eh_frame section.  Expect multiple iterations before
  this feature is ready for prime-time.

- Prevents stream of invalid "WARNING: possibly bogus exception frame"
  messages during initialization when run agains x86_64 xen dumpfiles
  created with the new "xm dump-core" facility.  (anderson at redhat.com)

- For for "struct -o" option to print structure member offsets if the
  member type is a function pointer.  (anderson at redhat.com)
