Wrap mysql_real_escape_string() in a function
Wrap mysql_real_escape_string() in a wrapper function db_escape_string() to ease porting to other databases, and as another step to pulling more of the database code into a central location. This is a rebased version of a patch by elij submitted about half a year ago. Thanks-to: elij <elij.mx@gmail.com> Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
