Add 1.7 methods to TimeZone / SimpleTimeZone

The RI documents the required implementation.

Unlike the RI, SimpleTimeZone in Android does not override
the TimeZone implementation: it seems pointless to do so
given it appears to rely on the implementation details of
another method (inDaylightTime()) which can, itself, be
overridden.
