CODING_STANDARDS addition re: emalloc

Attached is a patch that adds a new item to CODING_STANDARDS that suggests using emalloc() and friends over the standard C library version. It also offers an explanation, courtesy of Rasmus' reply to my earlier question on the subject. If no one objects to the addition in principle or in wording, I'll commit this in a few days. -- Jon Parise (jon@php.net) :: The PHP Project (http://www.php.net/)
