Initial checkin of junk code from my bzr tree.

Original tree was located at http://people.samba.org/bzr/jerry/slag/
Adding some scripts I wrote to help to the CVS/SVN to Git migration.

fix-commiter.pl	   -> Cleanup the committer listed in the *dat files
		      created by cvs2svn got git-fast-import
fix-svn-log.pl	   -> Trim preceeding whitespace from the body of "svn
		      log --incremental -r$REV"
strip_revisions.sh -> Strip CVSIN from the svn log output and generate
		      a list of revision IDs.
svn-janitor.sh	   -> Wrapper around fix-svn-log.pl to interate through all
		      revisions in an SVN repo.
parse_git_revs.pl  -> Generate a set of hashs to be cherry-picked from
		      a list of SVN revision numbers included in the commit
		      msg from git-svnimport (1.5.3.4).
Update README to say GPLv2 or later and remove references to bzr.
