Date checks

Issue: #3506
Closes: #3506

Value for an option is the number of full hours the date of the message
is in the past or future.

The symbol indicates that a date in Date: header has invalid format and
cannot be parsed by Rspamd.

Combine Date header checks into a single callback. No functional
changes.
