Port shared code information from the wiki

Since the shared code now has special status with respect to
copyrights, port them into a more structured format in the source tree
and add a python function that parses and returns a dictionary with
the information.

I need this to exclude these files from the Contributed-by changes and
I reckon it would be useful to know these files for future tooling.

+# The headers on most of these files indicate that glibc is the canonical
+# source for these files, although in many cases there seem to be useful
+# changes in the gnulib versions that could be merged back in. Not all gnulib
+# files contain such a header and it is not always consistent in its format, so
+# it would be useful to make sure that all gnulib files that are using glibc as
+# upstream have a greppable header.
+#
+# These files are quite hard to find without a header to grep for and each file
+# has to be compared manually so this list is likely incomplete or may contain
