Thanks Asterix for the initial version of this patch!

Each contact has now access to the account object instead of the account string.

Split the 'account sensitive' parts of the Contacts class and move them to an intermediate Contacts_New class.

The Contact class remains the public interface for contact handling. This is only a single step of a longer refactoring to empower the Account class.

Make the GC_Contacts class 'account insensitive'. Instead, create an Account class which holds a GC_Contacts object.

The API has been preserved. For now the old Contacts() API has not been changed.

This is similar to what has been done with the MetacontactManager

Public interfaces stay the same.

update correctly self_contact Contact instance and roster row when we use an anonymous account (our jid changes in this case). Fixes #5370

fix sending message to several contacts (in this case we cannot get a contact instance as there are several jids in one. Fixes #5408
