[Crash-utility] [PATCH 0/2] Display local variables & function parameters from stack frames

Hi Mohan, Sachin and myself have implemented this feature in crash to display local variables and arguments from vmcore dumps. This feature introduces a new command 'local' in crash utility which provides interface for stack unwinding along with option to display local variables and arguments. This patch is based on crash utility crash-4.0-8.9. It has dependency on libdw/libelf libraries provided by elfutils package. This has been tested on dumps taken on ppc64 machine. We were able to unwind the stack as well as display local variables, arguments. It currently displays values for non-optimized variables only (this fallows gdb's convention) TODO Items: 1. Support on x86_64 and x86 need to be implemented/tested 2. Makefile need to be updated to help packaging this feature Regards Sharyathi Nagesh
