issue #6167

This fixes a warning from PHPCompatiblity about a possible future
 conflict with PHP internal functions.

In a future version we should move all classes to namespace, but for now
 only moving Attribute class to avoid problems with PHP>=8 which have its
 own Attribute class.

 multivaluated attributes.

issue #6165

issue #6120

issue #6119

issue #6119

issue #6072

This replaces save_object and execute methods by 3 methods:
readPost - Reads POST data
update - Update object state
render - Render HTML UI

The point is to avoid reading POST and rendering HTML when this is not
 needed (when doing stuff through the webservice for instance).

It’s also more consisent across FD with all classes handling some kind
 of dialog implementing the new interface FusionDirectoryDialog which
 makes sure these 3 methods are implemented.

issue #6071

issue #6071

Use a thrown error instead of calling msg_dialog and exit.
And use an exception handler to format uncaught fatal errors.

issue #6071

issue #6071

issue #6071

msgPool always returns escaped string because it may be used from
 smarty.
htmlescape now calls htmlspecialchars instead of htmlentities, allowing
 to escape strings with % without losing sprintf capability.

issue #6071

This cleanup solves some more escaping problems

issue #6071

Adds FusionDirectoryError base class and one child class for check
 failures.
Use this new class for IntAttribute as first test.
Build HTML dialog from error class using attribute data.

issue #6071

Date modifier was returning an array of array instead of an array of
 strings, causing problems later on.

issue #6064

Removed useless read of CSN on dn "new"
Replaced calls to cat by calls to dn_exists when possible
Removed useless call to cat in prepare_save of new object

issue #6050

There was two functions for storing/getting object dn from session for
 no reason.

issue #6038

Also cleaned up "header" handling.
Removed print_header function which was doing two different things and
 misused in some places.

issue #6038

There is a check at login but we want to be able to lock config object
 from setup, before any login attempt.
