[Crash-utility] crash version 4.0-2.13 is available

- Adapted Takao Indoh of Fujitsu's patch for determining proper size of the ia64_init_stack; fixes empty ia64 "bt -a" output for cpu 8 and above for diskdumps generated via OS_INIT. - Applied a patch from Vladimir Kuznetsov to address a "net -s" error "net: invalid structure member offset: inet_opt_daddr" error due to the inet_opt structure being dropped between 2.6.10 and 2.6.11. - Made the initialization-time rule such that if "bt -O" is contained in any or all of the 3 possible initialization-time input files ($HOME/.crashrc, ./.crashrc, or "-i inputfile" files), the setting will remain idempotent. Fixed the redundant running of $HOME/.crashrc and ./.crashrc files if they are the same file. - Added a gdb work-around/hack for ia64 initialization-time warning "WARNING: cannot determine unw.tables offset" on rebuilt RHEL3 ia64 kernels that would prevent "bt" from working. - Backed out 4.0-2.11 x86_64 pseudo-backtrace patch to show in-kernel exception frame RIP and RSP values as a unique frame following the register dump; instead, the exception RIP address is translated and displayed prior to the register dump.
