Subject: ENGINE modules aren't special, so call them MODULES

The only thing that makes an ENGINE module special is its entry
points.  Other than that, it's a normal dynamically loadable module,
nothing special about it.  This change has us stop pretending anything
else.

We retain using ENGINE as a term for installation, because it's
related to a specific installation directory, and we therefore also
mark ENGINE modules specifically as such with an attribute in the
build.info files.

 ENGINES can only be used if configured with 'dynamic-engine'.
 This is usually a fault in a build.info file.
