LSR updates

[Phil Holmes]

I'm starting work on bringing the snippets in git up to date to match 
those in the LSR.  Stage one is to change the LSR address of dsi to di in 
them all and to bring their version numbers up to 2.18.0.  This isn't best 
done with makelsr because it does not blindly update sll the snippets, 
which is what we want.  I've used find and sed to make the needed changes 
and have a large patch ready to go with lots of changed files, but with 
only the changes above.  Does anyone object to my pushing it direct to 
staging following a make doc check locally?
