{ Enumerate the currently running protocols

  lParam=(LPARAM)(PROTOCOLDESCRIPTOR***)&ppProtocolDescriptors
  Returns 0 on success, nonzero on failure
  Neither wParam nor lParam may be NULL
  The list returned by this service is the protocol modules currently installed
  and running. It is not the complete list of all protocols that have ever been
  installed.
  IMPORTANT NOTE #1: the list returned is not static, it may be changed in the
  program's lifetime. Do not use this list in the global context, copy protocols
  names otherwise.
  IMPORTANT NOTE #2: in version 0.8 this service is mapped to the MS_PROTO_ENUMACCOUNTS
  service to provide the compatibility with old plugins (first three members of
  PROTOACCOUNT are equal to the old PROTOCOLDESCRIPTOR format). If you declare the
  MIRANDA_VER macro with value greater or equal to 0x800, use MS_PROTO_ENUMPROTOS
  service instead to obtain the list of running protocols instead of accounts.
  Note that a protocol module need not be an interface to an Internet server,
  they can be encryption and loads of other things, too.
  And yes, before you ask, that is triple indirection. Deal with it.

  Anytime before or during the ack or series of acks ACKRESULT_STATUS maybe sent, this might
  be sent a long while before anything else happens (or after anything happening) For avatars
  it allows callers to identify status information to do with the avatar, including the time
  before background transport has been created, so that you know an avatar will be exchanged
  sometime in the future.

  When ACKRESULT_STATUS, hProcess is the result code - the value of this is protocol dependent,
  See protocol documentation to do with avatars for what codes are defined and what they mean.
