Added state snapshot support for QemuD.

With this patch, both modem and sensor functionality are correctly
restored when a state snapshot is loaded. This was not the case
previously because communication with either of these services is
done using the qemud daemon, which did not support snapshots.

The boot-properties and charpipe services have no specific save/load
functionality yet, since the framework itself should be reviewed
first. Adding support for bootproperties should not be difficult
though, and charpipe may not need it.

For a description of the high-level process for saving and loading,
consult section IV "State snapshots" in docs/ANDROID-QEMUD.TXT.
