Extension scripts should never use CREATE OR REPLACE for initial object creation. If there is a collision with a pre-existing (probably user-created) object, we want extension installation to fail, not silently overwrite the user's object. Bloom and sslinfo both violated this precept. Also fix a number of scripts that had no standard header (the file name comment and the \echo...\quit guard). Probably the \echo...\quit hack is less important now than it was in 9.1 days, but that doesn't mean that individual extensions get to choose whether to use it or not. And fix a couple of evident copy-and-pasteos in file name comments. No need for back-patch: the REPLACE bugs are both new in 9.6, and the rest of this is pretty much cosmetic.
