{ *****  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.

  {
    A protocol might not support this cap, it allows a protocol to say that PFLAGNUM_2 is for
    statuses contacts supports, and that PFLAGNUM_5 is for statuses a protocol can SET TO ITSELF,
    if this is not replied to, then PFLAGNUM_2 is alone in telling you which statuses a protocol
    can set to and what statuses a contact can set to as well.

    E.g. A protocol might report 'wireless' users but a login of the protocol from Miranda can
    not set itself to 'wireless' so PFLAGNUM_2 would return PF2_ONTHEPHONE and PFLAGNUM_5 would
    return PF2_ONTHEPHONE as well, this means "I will get contacts who are on the phone but you can
    not set on the phone" and so on.

    Do note that the reply here is a NEGATION of bitflags reported for PFLAGNUM_2, e.g. returning
    PF2_ONTHEPHONE for PFLAGNUM_2 and returning the same for PFLAGNUM_5 says that you DO NOT SUPPORT
    PF2_ONTHEPHONE for the user to PS_SETSTATUS to, but you will expect other contacts to have
    that status, e.g. you can get onthephone for users but can't go online with onthephone.

    The same PF2_  status flags are used in the reply.

             Protocols are initially always in offline mode, if a protocol

             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 :
