Description of problem:

The RHEL7.3 errata version of the crash utility should be
rebased to the current upstream version, currently at version
crash-7.1.4.  There are over 50 new features and other fixes 
that have been applied to the upstream version make the tool 
significantly more useful than the current RHEL7.2 version, 
which is based upon crash-7.1.2.  This includes new options such
as "dis -s", "dis -f", "sys -i", "list -l", new support for QEMU
generated ARM64 ELF vmcores, and several updates required for 
support of recent upstream kernels, which is now relevant given
that the RHEL7 ARM64 kernel has been rebased to upstream Linux 
version 4.4.  

It is far more efficient, and far safer, to rebase the crash 
package than to attempt to selectively backport individual patches.
As the owner and upstream maintainer, one of my primary goals is,
and always has been, to maintain backwards-compatibility whenever 
new fixes or features are applied.  The risk of regression is 
less with a rebase than it would be with selective backports.

It should be noted that nothing goes into the upstream version 
without my approval.  I perform all my testing on Fedora and RHEL
kernel versions, where each individual change is meticulously 
tested against a sample set of RHEL3, RHEL4, RHEL5, RHEL6, RHEL7,
and Fedora crash dumps.
