[Crash-utility] crash version 4.0-3.20 is available

[Dave Anderson]

- Merged third round of "xencrash" patches, which allows a crash
  session to alternatively be brought up against the xen-syms
  binary instead of a vmlinux kernel.  This update introduces
  support for ia64.  (oda at valinux.co.jp)

- Verified support of live system analysis of ia64 xen kernels, and
  removed unnecessary EFI memory verification warning message during
  their initialization.  (anderson at redhat.com)

- Added gdb's "shell" command to the prohibited gdb command list, and
  updated the "help output" page to describe shell escape usage.

- Fix for the x86 "bt" command for the 2.6.20 kernel, which has added
  the "xgs" field to the pt_regs structure.  Without this patch, the
  exception frame dump in "bt" would show invalid contents for several
  registers; the fix also shows the GS register contents.

- Fix for the "mount" command for the 2.6.20 kernel to recognize the
  new "nsproxy" field in the task_struct and the contents of the
  nsproxy and mnt_namespace structures, in order to find the root
  mount namespace.  Without the patch, the command would fail with:
  "mount: invalid kernel virtual address: 69  type: first list entry".

- Fix for the "files" command for the 2.6.20 kernel to handle the
  removal of the fdtable "max_fdset" member.  Without the patch, the
  command would fail with: "files: invalid structure member offset:
  fdtable_max_fdset".  (anderson at redhat.com)

- Fix for the "net -[sS]" command options for the 2.6.20 kernel to
  handle the removal of the fdtable "max_fdset" member.  Without the
  patch, the command would fail with: "net: invalid structure member
  offset: fdtable_max_fdset".  (anderson at redhat.com)

- Fix for the "vm" command for the 2.6.20 kernel to handle the removal
  of the file structure's "f_dentry" member, and its placement inside
  the embedded "path" structure.  Without the patch the command would
  fail with: "vm: invalid structure member offset: file_f_dentry".

- Fix for the "swap" command for the 2.6.20 kernel to handle the removal
  of the file structure's "f_vfsmnt" member, and its placement inside
  the embedded "path" structure.  Without the patch the command would
  fail with: "swap: invalid structure member offset: file_f_vfsmnt".
