Remove workarounds to sort extensions.ini since ports tree now has a better solution in place to track PHP modules dependencies

Move copyright from ESF to Netgate

Uniformize memory limits and remove old code (revised)

1) Allow setting a memory_limit up to 768M (Suhosin)
2) Remove old workarounds. Memory limits on config.inc will be new defaults

(cherry picked from commit 7edcc54b2e9d1de51d5e6d0aedade89bc2cf0699)

Ensure extensions.ini is readable by non root users

https://redmine.pfsense.org/issues/6686

Review license / copyright on all files (1st round)

Set request_terminate_timeout to the same as max_execution_time in case something executed externally doesn't respond, to avoid hanging up all of php-fpm eventually. Ticket #6318 among other similar potential issues.

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/
