Hiraku Toyooka f615e2bb13 selftests/pstore: add pstore test scripts going with reboot
To test pstore in earnest, we have to cause kernel crash and check
pstore filesystem after reboot.

We add two scripts:
 - pstore_crash_test
     This script causes kernel crash and reboot. It is executed by
     'make run_pstore_crash' in selftests. It can also be used with kdump.
 - pstore_post_reboot_tests
     This script includes test cases which check pstore's behavior after
     crash and reboot. It is executed together with pstore_tests by
     'make run_tests [-C pstore]' in selftests.

The test cases in pstore_post_reboot_tests are currently following.

- Check pstore backend is registered
- Mount pstore filesystem
- Check dmesg/console/pmsg files exist in pstore filesystem
- Check dmesg/console files contain oops end marker
- Check pmsg file properly keeps the content written before crash
- Remove all files in pstore filesystem

Example usage is following.

  (before reboot)
  # cd /path/to/selftests
  # make run_tests -C pstore
  === Pstore unit tests (pstore_tests) ===
  UUID=b49b02cf-b0c2-4309-be43-b08c3971e37f
