Write object to message buffer.
When support for schema evolution is enabled the list of TStreamerInfo used to stream this object is kept in fInfos. This information is used by TSocket::Send that sends this list through the socket. This list is in turn used by TSocket::Recv to store the TStreamerInfo objects in the relevant TClass in case the TClass does not know yet about a particular class version. This feature is implemented to support clients and servers with either different ROOT versions or different user classes versions.
