[TYPO3-core] RFC: Feature Request 6037: Performance tunning in t3lib_div by removing elderly PHP functions

This is a SVN patch request.

There are some old-styled PHP functions in t3lib_div which could be done
in a better way nowadays. Those among are:
* while(list($k, $v)=each($arr)) --> foreach ($arr as $k => &$v)
* strstr($haystack, $needle) --> strpos($haystack, $needle)

Use the mentioned PHP functions to get a better performance.
Use references in foreach loops for a better performance (requires
PHP5), but this is the requirement for TYPO3 4.2 - thus, it's okay.

Thanks to Popy for creating the initial patch on this issue.
I left the function t3lib_div::trimExplode() untouched because there's
already a RFC created by Wolfgang/Masi on this list.
