Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Commit these apart because compile testing doesn't guarantee I didn't made
some nasty mistake. No functional change intended.
- Check for duplicated symbols and suggest moving them to ObsoleteVersions.
- Improve and unify error handling.
- Make the regular expressions more uniform, robust, and less sensitive
to harmless variations in the input such as those to whitespace amount.

Tested with: md5 (Version.map files in /usr/obj stay the same)
a set of symbol definitions (VERSION_DEF) and symbol mappings
(SYMBOL_MAPS).
Add an awk script to generate the version map.
