[TYPO3-core] RFC #14997: Performance: t3lib_db->escapeStrForLike() is using preg_replace, which is not necessary

[caspar at gosign.de]

This is an SVN patch request.

Type: Performance

Bugtracker references:
http://bugs.typo3.org/view.php?id=14997

Branches:
Trunk

Problem:
The function t3lib_db->escapeStrForLike() is using preg_replace to escape
the values '%' and '_' with a '\' for a sql-like-statement.
preg_replace takes a lot of recources and is not necessary for such a
simple replacement.

Solution:
use str_replace instead.
