[TYPO3-core] RFC #10511: simplify and speed up t3lib_div::trimExplode()

[Steffen Kamper]

Hi Ingo,

+1 by testing and reading.

Though there is an issue remaining with limit, but it gives wrong result 
also with existing function

$a = 's ,, d  ' . chr(10) . chr(9).', d,eee';
$content .= t3lib_div::view_array(t3lib_div::trimExplode(',', $a, true, 3));

Limit is set to 3, but returning array contains only 2 elements, line 
break is not removed.
