Import a slightly modified Bayou version into svn. This is based
on the last snapshot posted by Jordan Crouse. This commit is long overdue. Changes by me include: - Rename 'utils' to 'util' for consistency with our other projects. - Move the main code out of src/* into the top-level directory. - Add missing license headers to the following files: Makefile, pbuilder/liblar/Makefile, util/pbuilder/Makefile. - Dropped the util/pbuilder/lzma completely. I'm working on reusing the lzma/ dir from v3 via svn:externals. Alas, this also means that Bayou won't yet compile out of the box. - Coding-style and white-space fixes (indent) for all files.
