Subject: [PATCH 02/43] [HttpFoundation] Added structured namespacing to
 session attributes.

The use of references in this PR are entirely functional and required for
set() methods, however in the case of reading, they are not necessary.
They are probably not doing any harm, but the rule of thumb in PHP 5
is to only use references for functionality reasons.

+ * Session Savehandler Interface.
+ * 
+ * This interface is for implementing methods required for the 
+ * session_set_save_handler() function.
+ * 
+ * @see http://php.net/session_set_save_handler
+ * 
+ * These are methods called by PHP when the session is started 
+ * and closed and for various house-keeping tasks required
+ * by session management.
+ * 
+ * PHP requires session save handlers.  There are some defaults set automatically
+ * when PHP starts, but these can be overriden using this command if you need anything
+ * other than PHP's default handling.
+ * 
+ * When the session starts, PHP will call the sessionRead() handler which should return a string 
+ * extactly as stored (which will have been encoded by PHP using a special session serializer 
+ * session_decode() which is different to the serialize() function.  PHP will then populate these 
+ * into $_SESSION.
+ * 
+ * When PHP shuts down, the sessionWrite() handler is called and will pass the $_SESSION contents
+ * to be stored.  Again PHP will automatically serialize these itself using session_encode()
+ * 
+ * When a session is specifically destroyed, PHP will call the sessionDestroy() handler with the
+ * session ID.  This happens when the session is regenerated for example and th handler 
+ * MUST delete the session by ID from the persistent storage immediately.
+ * 
+ * PHP will call sessionGc() from time to time to expire any session records according to the
+ * set max lifetime of a session.  This routine should delete all records from persistent
+ * storage which were last accessed longer than the $lifetime.
+ * 
+ * PHP sessionOpen() and sessionClose() are pretty much redundant and can return true.

Subject: [PATCH 25/43] [HttpFoundation][FrameworkBundle][SecurityBundle] Make
 parameters consistent.

Changed session.storage.native to session.storage.nativefile to be consistent with naming standards.

Changed SecurityBundle/Tests/Functional/app/config/framework.yml to use session.storage.nativefile by default (works perfectly for function testing and makes session.storage.filesystem redundant).

[HttpFoundation] Fixed FilesystemSessionStorage sessionWrite() not saving data.

[HttpFoundation] Fixed mixed up prefix implementation between memcache and memcached.

  * [BC BREAK] SessionStorageInterface has been altered and now requires an instance of
    FlashBagInterface and AttributesBagInterface; and optionally implement SessionSaveHandlerInterface
    to implement custom session save handlers.
+ * Session object takes two additional object in the constructor: AttributesBagInterface and
+   FlashBagInterface.
  * Added AbstractSessionStorage base class for session storage drivers.
  * Moved attribute storage to AttributesBagInterface.
  * Added AttributesNamespacedBag for namespace session attributes.

+ * [BC BREAK] Moved flash messages out of the `Session` class and into `FlashBagInterface`.

Subject: [PATCH 43/43] [HttpFoundation][FrameworkBundle][SecurityBundle]
 Introduced mock session testing with persistence to the file system.

This commit introduces save() in a way that does not interfere with the
PHP session workflow.  Under normal circumstances this method doesn't need to be
invoked at all and if it is, it will force the session to write using
session_write_close(). When under test, the mock session storage driver can persist the
session data as and if required.
