[TYPO3-core] RFC: #13675: Use array_map() for t3lib_div::intExplode

[Georg Ringer]

Hey,

this is a SVN patch request.

Type: performance tuning

Branch: trunk, 4.3,4.2

BT reference: http://bugs.typo3.org/view.php?id=13675

Problem:
t3lib_div::intExplode can be a lot faster by using array_map instead of
a foreach and using a reference.

It needs about a third of the time in the given testcase

Solution:
Use array_map('intval', $temp);

Additional information:
- Thanks to Nikolas Hagelstein, how brought up the idea

- A simple testcase is in the bugtracker
