If the handle version is 0, there's no hardware_backed flag
meaning hardware backed handles will be attempted against
the soft impl. Ensure we don't try to read from hardware_backed
unless the version is > 0.

Certain devices, like Shamu, are currently running an interim
software-only gatekeeper. When the HAL for those devices is merged,
we need to handle upgrading to the HAL smoothly.

Allows for easy determination of whether there's a
hardware module in place. Permits tighter coupling of
software implementation with upper-level stack.

This allows us to recover in situations where we manage
to clear the SID in GateKeeper but fail to remove the
password in LockSettingsService.

It's a bit weird that KS defines NO_ERROR outside a
namespace like the Android binder lib, but assigns
it the value 1 instead of 0.

Until we have SELinux support for gating access
to individual TEE services, we will proxy TEE requests
to GateKeeper via this daemon.
