Changes:
Security and robustness release. Notable cramfsck changes:
* Reject dirent names containing "/", "." or ".." to close a path
traversal during `cramfsck -x` (reported in issue #12).
* Open regular files with O_CREAT|O_EXCL during extraction to
prevent duplicate-dirent attacks from truncating files reached
via a previously-extracted symlink.
* Fix outbuffer NUL termination and a 1-byte overflow in
do_symlink when running with both -v and -x.
* Harden romfs_read against truncated/malformed images by
zero-filling the window buffer and checking lseek/read returns.
* Reject directory entries that extend past their parent's size.
Documentation: README now documents cramfsck and lists all current
mkcramfs options; stale hard-link and endianness claims corrected;
NOTES trimmed of the 25-year-old Future Development section.
