Fix AnalogClock rendering

1. Change calls to java.lang.System.log* since they don't exist on the
host.
2. Clean up method rewrite mechanism in ReplaceMethodCallsAdapter.
3. Stub out creation of uninitialized GregorianCalendar.
4. Memory map the time zone data base file and provide a custom
implementation of BufferIterator for use by ZoneInfoDB
5. Delete unused Time_Delegate

Also fixed a comment in BridgeAssetManager and an error message in
FontFamily_Delegate.
