TestDateFormatRelative fails on 5 Nov 2007

OK, a number of problems here.

• The test was trying to add/subtract multiples of 86400000 milliseconds to the current time to get "today", "tomorrow", "day before yesterday" etc. This doesn't work around DST changes, such as happened on 4th Nov 2007
• the test has been changed to have an "add" type of semantic - simply add or subtract a day from the calendar
• this uncovered a bug in the underlying relative calculations - it would consider from 9pm one day to 9am the next day to be "Today" because it used the fieldDifference() API. This seemed like a good idea at the time, but it fails because subtracting 1 day from "tomorrow 9am" becomes "today 9am" which is before "today 9pm" and thus the difference calculation stops, thinking that it has overshot. I have changed the implementation to simply take the difference between the target date's modified julian day and today's modified julian day. This will result in a scalar number of days that is negative for prior days, positive for future days, and zero for today - all day.

Also some calendar debug code was updated.

We need to update ICU4J code to support "RELATIVE_ADD:DATE=x". I move it back to un-reviewed and Steven will update the Java code.

fixed for J

updated C test
