Addition of new time zone lookup code
Introduction of libcore.util.TimeZoneFinder for
resolving time zones by country / by country + offset
information.
This code is intended to be a work-a-like replacement
for code currently residing in android.util.TimeUtils
and using time_zones_by_country.xml in the plaform.
android.util.TimeUtils and
com.android.internal.telephony.ServiceStateTracker will
be switched over to using it in a follow up change.
At present, the algorithm should return the same
logical results as the code it is intended to replace.
A notable difference is that it uses ICU's TimeZone class
instead of java.util.TimeZone because
it has more convenient methods and the ability to
freeze timezones. More care has been taken to return
immutable data structures than the code it replaces.
This change also changes the TimeZoneDistroInstaller
and associated classes / tests to be aware of and
require the new file.
