Updated Netware makefile

Makefile.netware (via an AWK script) used to pull the version numbers
from configure.ac.  Since they are no longer there, 'configure.ac' puts
them into 'configure' for Makefile.netware to find.  This change makes
it look there.

NOTE: This has not been tested on a Netware system.
Added new files to CMakeLists.txt.

Added new sources and tests to the relevant CMakeLists.txt files.

NOTE: cmake doesn't work for me so I have no idea if this is correct.
