Relax Suhosin to allow a 512M memory limit

Reduce log level for RELEASE versions. Fixes #6178

Revert part of 475f0b6db committed by accident

Stop processing when find it

Add missing PHP modules, it should fix #6041

Simplify logic

Ensure the extensions.ini has no duplications before setting up php.ini. Fixes #5943

Strengthen PHP session settings

See https://secure.php.net/manual/en/session.configuration.php#ini.session.hash-function

Revert maximum array depth (aka input nesting level) to default values

This is per default 50 in Suhosin (*.max_array_depth) and 64 in PHP (max_input_nesting_level)

Note: Array depth is not the number of elements within an array.

Increase max_input_vars

Since Suhosin has a configured limit of 5000 maximum input variables, for consistency, PHP should be configured with a similar setting (the default is just 1000). This will allow BIG forms to save without any problem in the future.

Rename php-fpm pool from lighty to nginx

Include www/classes and www/classes/Form in the PHP include path

Remove /usr/local/lib/php.ini, we don't need 2 copies of this

Introduce read_global_var:

- Add a new script, read_global_var, that returns the value of any item
contained in global array $g
- Replace all grep and sed magic from shell scripts

Introduce read_xml_tag.sh

Create /usr/local/sbin/read_xml_tag.sh, that will read a xml tag from
config file using xmllint. Replace all direct read using cat, grep, sed,
... by this script

Fix #5220, setup PHP timezone:

- Get defined zoneinfo in the following order:
- /var/db/zoneinfo
- /cf/conf/config.xml
- /etc/inc/globals_override.inc
- /etc/inc/globals.inc

Consider globals_override.inc and replace hard coded pfSense string by product_name

Use PHP 5.6 extensions dir

Do not explicit add opcache to zend_extension, just enable or disable it

Remove ioncube references from php.ini, and set zend_extensions properly

Move opcache to zend_extensions

Move main pfSense content to src/
