Commit 3dea5890 3dea5890547c7ec7f941660d011fb82fed1b174a by Alain Magloire
Options

In order to provide inheritance, it is necessary to make 

	the base functions/methods visible so the extended object
	could reuse some base methods if necessary.  Inheritance
	is possible because we always add to the end of the vtable
	structure new functions.
	For example, mime_t object will be also a message_t.
	and it will be possible to do
	{
	  mime_t mime;
	  header_t header;
	  ...
	  message_get_header ((message_t)mime, header);
	}
	Another example is tcpstream(socket stream) extends
	fdstream(file description stream);
	Also the name of the functions have change to match better
	there purpose.

	* mailbox2/bstream.c: Reoganisation to make the
	functions visible.
