tree-walk: use size_t consistently
We store and manipulate the cumulative traverse_info.pathlen as an "int", which can overflow when we are fed ridiculously long pathnames (e.g., ones at the edge of 2GB or 4GB, even if the individual tree entry names are smaller than that). The results can be confusing, though after some prodding I was not able to use this integer overflow to cause an under-allocated buffer. Let's consistently use size_t to generate and store these, and make sure our addition doesn't overflow. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
