Fixed bug #74600 and #74738

[manuelm]

Make sure the hash entry is an array.

The origin fix broke support for HOST/PATH ini sections. Only the beginning of the string has to match. Revert this check but use zend_binary_strncasecmp instead of strncasecmp.

[laruence]

what kind of usage does the origin fix break? could you make a example

[manuelm]

It broke support for HOST/PATH ini sections. See http://php.net/manual/en/ini.sections.php

e.g.

# cat a.ini
memory_limit=10M
[PATH=/should/not/match]
memory_limit=20M

# 7.0.20
# ./sapi/cli/php -c a.ini -i | grep memory_limit
memory_limit => 20M => 20M

# 7.0.19
# php7.0 -c a.ini -i | grep memory_limit
memory_limit => 10M => 10M

To better understand the bug #74600 the ini file can also be rewritten as:

memory_limit = 10M
[PATH=memory_limit]
a = b

I can add tests later as well. Most important was to fix this issue as it broke all customer ini settings.
