[boost] Iostreams 'drain' algorithm proposal

Hello list.

New here, but a Boost user so thought it was time I started lurking with a 
view to contributing.

When using boost::iostreams, I find I frequently need/implement a 'drain' 
algorithm. This is identical to boost::iostreams::copy, except that it 
doesn't close the Sink. This allows mutiple sources to be 'drained' into a 
single sink.

Unless there is a generic algorithm for doing this that I have missed, I'd 
like to propose the addition of the 'drain' algorithm to boost::iostreams.

I have a patch, should there be any interest.
