       Fixes PR libgcj/17002:
       * java/util/TimeZone.java (defaultZone): Try a couple of ways to get
       a TimeZoneId string and then try to convert that to a TimeZone with
       getDefaultSystemTimeZone(String).
       (timezones0): Changed type from Hashtable to HashMap.
       (timezones): Create HashMap, not Hashtable.
       (getDefaultTimeZone): New method, rewritten from CNI version.
       (readTimeZoneFile): New method.
       (readtzFile): Likewise.
       (skipFully): Likewise.
       * java/util/natTimeZone.cc (getSystemTimeZone): Renamed to
       getDefaultTimeZoneId and rewritten.
       (getDefaultTimeZoneId): Rewritten in java.
