Prevent an integer overflow in mutt_mktime() (closes #3880)
Check to make sure the year passed in isn't bigger than can be
represented using time_t on the platform.
Also add a (time_t) cast to an intermediate "years * 365" calculation
to prevent an overflow there.
Thanks to TAKAHASHI Tamotsu for his patch, and to Vincent Lefèvre for
his improvement. I merely took their code and commited it.
