Netflix reported that after pulling power while their app is active,
the app isn't able to restart. This is because the license file for
session keys isn't getting synched to disk, so the data is still in
the buffer cache when the device shuts down. Calling fflush and fsync
on the file ensures the data is persisted to disk. fclose alone
doesn't do fsync.
In testing, I also noticed that the license file was being rewritten
every second which is hard on the flash filesystem. The timer thread
was modified to avoid these frequent writes.

Certificates and offline licenses are stored in security level
specific directories in klp. When devices transition from jb-mr2,
their persistent information has to be ported to these directories.
