crash bug fix and enhancement update

Updated crash packages that fix several bugs and add an enhancement are
now available.

The crash packages are used to investigate live systems, and kernel core
dumps created from the netdump, diskdump and kdump facilities.

These updated packages fix the following bugs:

* when loading module debuginfo, the crash utilities "mod" command first
searched the "/lib/modules/[kernel-release]/" directory, before the
"/lib/modules/[kernel-release]/updates/" directory. In these updated
packages, the crash utilities "mod" command is consistent with other
module utilities, such as depmod, modprobe, and insmod, and now searches
the "/lib/modules/[kernel-release]/updates/" directory, before the
"/lib/modules/[kernel-release]/" directory.

* crash was unable to analyze a vmcore that had been created from a kernel
that had overrun its kernel stack. Such a kernel corrupted the
"thread_info" structure, which is read and used by the crash utility as a
per-CPU index into an internal array, resulting in a segmentation fault
during initialization.

As well, these updated packages add the following enhancement:

* a crash-devel package, which contains extension modules, has been added.
This package installs the "defs.h" file into the "/usr/include/crash/"
directory. For example, the crash utility can now dump relayfs buffers,
which are used by SystemTap.

Users of crash are advised to upgrade to these updated packages, which
resolve these issues and add this enhancement.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
