• Fixed handling of two last clusters: operations with files that occupy these clusters could fail.
• Fixed crash when started with stdin, stdout or stderr closed.
• Improved reliability in case of a sudden unplug: FS will be in a clean state after closing all files and performing sync(1).
• Fixed heap corruption: malformed FS can use invalid sector or cluster size.
• Fixed hang on mount: malformed FS can have cyclic references in the clusters map.
• Fixed wrong files names hashes when upper case table is compressed.

Builds, installs, brief testing seems OK.
