[Crash-utility] crash version 4.0-3.18 is available

- Enhancement to the "mod" command to expand the number of section arguments to the internal "add-symbol-file" command issued to gdb to load the debug data for module objects. On most architectures, this allows the usage of the command construct "p [module-symbol-name]" to print out the module data structure in the same way that is done for kernel proper data structure names. (castor.fu(a)3pardata.com) - Two enhancements to significantly speed up the initialization of crash sessions when running against multi-gigabyte xen kernels or xendumps. The cache of mfn-to-phys_to_machine_mapping page has been changed from a single-mfn-to-phys_to_machine_mapping page format to storing a contiguous-range-of-mfns-to-phys_to_machine_mapping format. This benefit is primarily seen during the "gathering module symbol data" phase. The second change simply increases the size of the pfn-to-xendump-page-offset cache. (anderson(a)redhat.com) - Fix for a segmentation violation during the "gathering task table data" phase of initialization if the thread_info structure of the runqueue-advertised active task has been freed. This has only ever been seen in a xendump created by "xm dump-core -L [guest-domain]". (anderson(a)redhat.com) - Cosmetic fix to prepend newlines to messages that happen to be generated during any of the "please wait" segments of initialization. (anderson(a)redhat.com) - Addressed several compiler warnings when using -D_FORTIFY_SOURCE=2. Some are in gdb code that is never exercised, others were legitimate but would require impossible code paths, but one of them could result in runaway "help -t" output if the kernel was built without IKCONFIG. (bwalle(a)suse.de) - Fix for the s390x "bt -f" command option, which was displaying the stack as a sequence of 32-bit words which were dumped "backwards", i.e., at the wrong offset.
