spdxconv: tool to convert license and copyright to SPDX format

This is the initial implementation, work in progress, with the following
functions,

* loading the spdxconv.cfg file
* scanning list of files to be converted
* detect .git repository and exclude files ignored by .gitignore

No conversion logic is implemented yet.
