Archive FreeBSD kernel crash files

The bsdcrashtar utility creates tar a archive that contains all files needed for debugging FreeBSD kernel crash vmcore, kernel, loaded modules, sources that appear in backtrace. This is useful for debugging a crash on another host, sending it to developers or if you are going to upgrade the kernel on crashed host but would like to keep crashdump in case the developers ask you to provide additional info.

Created tar archive contains also a script that when being run inside unpacked archive will give kgdb1 session with crash core loaded in it. The script should be run with root privileges because it does chroot8 before starting kgdb1.
