Subject: [PATCH v2 0/2] selftests/pstore: add pstore test script

These scripts include test cases which check pstore behavior. This
is useful to avoid regressions of pstore.

Changes since v1:
 * Exit with 1 in pstore/Makefile when pstore_crash_test failed.
 * Create helper functions to make the tests much more readable.
 * Use /sys/module/pstore/parameters/backend to check pstore backend is
   registered.
 * Show content of /sys/module/.../backend and /proc/cmdline for debug
 * Give UUID to each execution of test script.
 * Write unique test string with UUID into pmsg.
 * Check only one test string pattern appears in pmsg after crash.
 * Check UUID written to pmsg matches across crash.
 * Don't touch panic_on_oops because it is not necessary for reboot on crash

(v1: http://www.kernelhub.org/?msg=831044&p=2)

I also confirmed that these scripts work fine with kdump reboot with
kernel boot parameter 'crash_kexec_post_notifiers'.
