Re: #290: Motivate one-year limit for Expires

Updated proposal:

Remove the requirement in p6 3.3 and replace it with:

"""
Historically, HTTP required the Expires field-value to be no more than a year in the future. While longer freshness lifetimes are no longer prohibited, extremely large values have been demonstrated to cause problems (e.g., clock overflows due to use of 32-bit integers for time values), and most caches will evict a response far sooner than that. Therefore, senders ought not produce them.
