"encoding: binary" comments for all sources (1.9)

This ensures any string literals that pop up in *our* code will
just be a bag of bytes.  This shouldn't affect/fix/break
existing apps in most cases, but most constants will always have
the "correct" encoding (none!) to be consistent with HTTP/socket
expectations.  Since this comment affects things only on a
per-source basis, it won't affect existing apps with the
exception of strings we pass to the Rack application.

This will eventually allow us to get rid of that Unicorn::Z
constant, too.
