Replace almost all remaining reference to the MODULENAME macro

Replace almost all remaining reference to the MODULENAME macro
with references to a corresponding variable name.

This change is part of a project to split up the oils_cstore module
into an interface module (consisting mostly of osrfAppChildInit(),
osrfAppInitialize(), and osrfAppChildExit()) and an implementation
module (consisting of pretty much everything else).  The implementation
module will then be available for reuse in other contexts.
