Caption is covering the app region and will take gesture and tap events
when the user interact with the caption. This change will make sure the
app can receive the caption as a part of the tappable element insets and
gesture insets to avoid the caption overlaps with interactive elements
inside the window.

Generate the new seed by hashing the old seed together with some bytes
from /dev/urandom, rather than just using the bytes from /dev/urandom
alone.  This ensures that the new seed doesn't contain less entropy than
the old one, and follows the latest recommended best practices.

While doing this, also clean up various other things:

- Start using AtomicFile to update the seed file so that it won't be
  corrupted if the system crashes while it is being updated.
- Eliminate the RandomBlock class, as it isn't very useful.
- Send all the device-specific information to /dev/urandom in one write.
- Improve comments, variable names, and method names.
- Improve log messages, e.g. don't log a warning on every first boot.
- Improve the unit test.
- Use @VisibleForTesting rather than an ad-hoc comment.

Exclude the static library `android.hardware.contexthub-V1.0-java` from
system_server, as it's already included in the framework. This avoids a
collision between SYSTEMSERVERCLASSPATH and BOOTCLASSPATH.
