Description:
------------
if a ini file has a "(" or ")" in it the parse_ini_file function will end on the character before the "(" or ")". in some cases or remove the "(" and ")" or just dump everything between the "(" and ")".

In a nut shell it hates "(" and ")" for some reason.

Reproduce code:
---------------
sample "demo.ini" file:

[demo]
a=1
b=(
c=3

php -r "print_r(parse_ini_file('demo.ini', true));"


Expected result:
----------------
Array
(
    [demo] => Array
        (
            [a] => 1
            [b] => (
            [c] => 3
        )

)

Actual result:
--------------
Warning: Error parsing demo.ini on line 3
Array
(
    [demo] => Array
        (
            [a] => 1
            [b] =>
        )

)
