DateTime for #53437 5.3/5.4

Hi, I just wanted to address again these two patches to be applied in 5.3/5.4 http://git.php.net/?p=php-src.git;a=commitdiff;h=0ee71557ffd285552659b6aa37ea236e3bad493f http://git.php.net/?p=php-src.git;a=commitdiff;h=fa3fc711d3fb54bf1746138ffcf7f46426921204 Both are in 5.5 already for some weeks, tested and proven to fix the crash in unserializing the DateTime object family. The important points do welcome this fix are - we deal with crash vs. bailout here - no other patch is available - a finer handling could introduce even more behaviour changes The history of this fix recalls the ticket from back more than 3 years ago https://bugs.php.net/53437 . The changes was considered OK by Derick and I'd really go on to apply those patches to 5.3+ as a clean die is in any case more vital than crash. That would fix the last known crash in 5.3/5.4, that might make very much sense to put those in. Thanks Anatol
