selftests/pstore: add pstore test script for pre-reboot
The pstore_tests script includes test cases which check pstore's
behavior before crash (and reboot).
The test cases are currently following.
- Check pstore backend is registered
- Check pstore console is registered
- Check /dev/pmsg0 exists
- Write unique string to /dev/pmsg0
The unique string written to /dev/pmsg includes UUID. The UUID is also
left in 'uuid' file in order to enable us to check if the pmsg keeps the
string correctly after reboot.
Example usage is following.
# cd /path/to/selftests
# make run_tests -C pstore (or just .pstore/pstore_tests)
make: Entering directory '/path/to/selftests/pstore'

selftests: pstore_tests [PASS]

We can also see test logs later.
