preproc.py script from another project. Had to further develop it to get around the amazingly complicated preprocessor usage in the scmos subdirectory. Needed to add handling of parameterized definitions; could not figure out how to align the syntax used in scmos/extract_template with any consistent syntax. Gave up and rewrote some of the contents of extract_template to avoid the more ambiguous usage. All of this is to support a completely deprecated scmos.tech. However, it does avoid both the M4 and cpp preprocessors altogether. Also did auto-detection of python3 in the configure script for use of the preproc.py preprocessor, and applied the same preprocessor to the macro definitions.
