-X (freespace) change. Requires existing base directory.

Further updates to scrub_free and -X handling. Now requires a base directory to exist and will create a random directory under using mkdtemp(). Also made slight change to man page to clarify -X option handling.

Thanks. A few changes please:

• squash these commits since second one modifies changes in the first one
• refer to directory argument as "directory" or "dir" not "basedir" (be consistent)
• don't change the error -X only takes one directory name. We're not listing all the options that work here.
• instead of char freespacedir[13]; and a later strcpy. Instead use static initialization without a size.
• drop comment construct relative path to temp directory in snprint
• fix directory spellling and s on exists in -X base diirectory %s does not exists

Thanks for the feedback. I'll clean up tomorrow. Will resync and make consistent.

At least it works! 😀
