refactor test-date interface
The test-date program goes back to the early days of git, where it was presumably used to do manual sanity checks on changes to the date code. However, it is not actually used by the test suite to do any sort of automatic of systematic tests. This patch refactors the interface to the program to try to make it more suitable for use by the test suite. There should be no fallouts to changing the interface since it is not actually installed and is not internally called by any other programs. The changes are: - add a "mode" parameter so the caller can specify which operation to test - add a mode to test relative date output from show_date - allow faking a fixed time via the TEST_DATE_NOW environment variable, which allows consistent automated testing - drop the use of ctime for showing dates in favor of our internal iso8601 printing routines. The ctime output is somewhat redundant (because of the day-of-week) which makes writing test cases more annoying.
