Add export_tarball tool.

It creates a .bz2 tarball with all the sources, but without
.svn directories, and has an option to remove files
which are not required for build, and take a lot of space.

+"""
+This tool creates a tarball with all the sources, but without .svn directories.
+
+It can also remove files which are not strictly required for build, so that
+the resulting tarball can be reasonably small (last time it was ~110 MB).
+
+Example usage (make sure gclient is in your PATH):
+
+export_tarball.py /foo/bar
+
+The above will create file /foo/bar.tar.bz2.
