  Log:
  . Fix the look up of time zone data when TZUPDATE is turned on and as a
    result turn it on by default again.  This change bears a little more
    explanation.
  
    In UnixFileSystem.java there is a cache of canonical paths and in
    particular one for paths inside java.home.  The problem with looking
    up time zone data is that if another path within java.home has been
    looked up then the symlink for the time zone data is not resolved
    (since the cache assumes there are no symlinks in java.home) and we fail
    to be able to open the ZoneInfoMapping file.
  
    One of the other features in UnixFileSystem is that the cache is not
    consulted and full resolution occurs for paths containing "." or "..".
    I've chosen to (ab)use this to force resolution of the time zone data
    directory in ZoneInfoFile.java rather than doing something like IcedTea
    did which was to introduce a tz.properties file where they would stash
    the time zone info directory rather than symlinking it in.  For full
    reference that patch is here:
  
    http://icedtea.classpath.org/hg/icedtea6/file/tip/patches/use-system-tzdata.patch
  
    There are two main reasons I chose a bit of a hack rather than something
    like this.
  
    1. I want to apply the patch to non-GPL'ed code (e.g. the jdk16 port).
    2. Using updated time zone data is only an option in the port and using
       something like tz.properties when the option is off is clunky.
  
    Thanks to avg@ for sleuth work on finding the bug write up and the
    IcedTea fix.
