code coverage report for gnulib

[Simon Josefsson]

All,

I prepared a code coverage report for gnulib:

http://www.gnu.org/software/gnulib/coverage/

There is a bug in the tool that results in duplicated */foo/foo
directories, but hopefully that will be debugged later on.  The output
above should be useful to indicate where more self tests are needed.

Note that if NO code in a file is called, that file will not be listed
on that page.  So it is difficult to know how large percentage of the
entire gnulib code is covered by self tests.  Also, this was built on my
machine, which may be recent enough to not cause many gnulib modules to
be enabled.
