[h323plus] max RTP PDU size

.1. It looks to me like proper packetization is left to the encoder and that the max PDU size is actually outputDataSize, computed in h323pluginmgr.cxx!H323PluginVideoCodec::Read() by asking the encoder through CallCodecControl(GET_OUTPUT_DATA_SIZE_CONTROL).

However I can not seem to find a way for the application to specify a different max PDU size (a lower one in my case) or even a way to tell the encoder of such a choice (there is no SET_OUTPUT_DATA_SIZE_CONTROL). Is it possible to limit the max PDU size?

.2. In h323pluginmgr.cxx!CallCodecControl(), wouldn't it make more sense to pass the normalized codecControls->name to (*codecControls->control) instead of name? After, you are doing a case-insensitive comparison.
