Hi, here are the patches to enhance existing MB handling. This time

I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:

SET CLIENT_ENCODING TO 'encoding';

Other features include:
	Latin1 support more 8 bit cleaness

See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.
