The sprintf function has been normalized to php_sprintf via
61364b5bb1.
This patch removes the checks to make a custom sprintf function
The ZEND_BROKEN_SPRINTF has been removed and the
hardcoded #define zend_sprintf sprintf is used.
The php_sprintf and zend_sprintf are now symbols to sprintf.
This patch now removes the custom PHP definitions of the php_sprintf and
zend_sprintf functions in favor of the C99 sprintf which is also
standardized in C89 already. Once, on some systems sprintf didn't behave
in same way.
