Add fstree independend directory writer to libsquashfs.so
This commit adds a directory writer to libsquashfs that wrapps a meta data writer and provides a higher-level interface for writing directory entries. Under the hood it enforces the rules that squashfs insists upon. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
