{ *****  Unicode Services note   ********
******************************************

Only new style protocols (Miranda 0.9+) with m_iVersion set to 2 or higher
support Unicode services documented below, all other support only ANSI.

For all other that do not support Unicode services, Miranda core will
convert Unicode to ANSI and call the appropriate service.

    none of these services should be used on there own (i.e. using CallService(), etc)
    hence the PS_ prefix, instead use the services exposed in m_protocols.inc

    these should be called with CallProtoService which prefixes the protocol module
    name before calling.
    -
    Deleting contacts from protocols that store the contact list on the server:
    If a contact is deleted while the protocol is online, it is expected that the
    protocol will have hooked me_db_contact_deleted and take the appropriate
    action by itself.
    If a contact is deleted while the protocol is offline, the contact list will
    display a message to the user about the problem, and set the byte setting
    "CList"/"Delete" to 1. Each time such a protocol changes status from offline
    or connecting to online the contact list will check for contacts with this
    flag set and delete them at that time. Your hook for me_db_contact_deleted
    will pick this up and everything will be good.

             Protocols are initially always in offline mode, if a protocol
             doesn't support a specific status mode, it should pick the closest
             ones that it does support, and change to that.

             If a protocol has to switch from offline mode to online (or a substate
             of online, like away) then it should report any errors in the
             form of an additional ack :

             type=ACKTYPE_LOGIN, result=ACKRESULT_FAILURE, hProcess=NULL, lParam=LOGINERR_*

             SetStatus() is called when a protocol module is first loaded
