Patches to update --version copyright notices

["Joseph S. Myers" <joseph at codesourcery dot com>]

I've applied the attached patches to update --version copyright notices to 
say 2006 (mainline and active release branches), per the FSF principles 
that (1) the --version date should be just the most recent year, not a 
list of dates and (2) the dates should cover all changes to the package 
rather than needing to track when particular parts changed.  (If we really 
want to apply that principle to *all* copyright notices, and update every 
file on January 1 each year rather than subsequently forgetting to update 
notices, we'll need a script to do so.)

I've only touched gcc/, not programs outside there (e.g. libjava) with 
--version copyright notices, and haven't touched the various such notices 
in gcc/ada (which use ranges of years and in some cases are in the name of 
the FSF, in other cases in the name of AdaCore).
