vnc fixes and improvements (Stefano Stabellini)

Browse source 
this patch fixes a bug and improves the generic pixel conversion
function in vnc.c.
The bug is that when a new vnc client connects we need to reset the flag
has_WMVi but currently we don't.
The generic pixel conversion function is vnc_convert_pixel and currently
is not very efficient since uses the division and multiplication
operators.
To make it more efficient I changed to use bit shift operators instead.
