[boost] Filtered stream-buffer, part 2

For the past few weeks, some posters were talking about streambufs that 
can decorate another stream buffer.  I wrote up a second version at 
<http://groups.yahoo.com/group/boost/files/filter_stream.hpp>.

It moves the calling functions to the stream buffer class.  It adds 
example filtering functions to the filter class.  Management controls 
in the filter class have been made private, with the stream buffer 
class as a friend, to minimize subversion.

There's a bunch of allocator and string declarations in the code 
unused.  I was thinking of using them as buffers for extra characters 
read and/or written when the remaining stream buffer functions are 
modified.
