Rather than having a second pool implementation only for CDS, use
the generic pool implementation.  This also uses the abstract resource
identifiers to identify CDS blocks, rather than a direct reference.

Add the system-specific module suffix (.o, .so, .obj, etc) and the
default CFE core executable name to the configdata structure.

This information has several useful purposes.

Adds an #ifndef empty string for the two new fields, which
at the very least prevents IDEs (e.g. Eclipse) from redlining
the value as an undefined symbol.

(It is always passed in on command line when building via CMake)
