sysutils/fusefs-encfs: 1.7.4 -> 1.8.1

• submitter becomes maintainer
• reverse: re-enable kernel cache (bug #60)
• reverse mode: disable unique IV by default (was enabled in 1.8)
• add make benchmark-reverse
• remove -o default_permissions unless needed to improve performance
• add option --require-macs (bug #14)
• add per-file IVs based on the inode number to reverse mode to improve security
• add automatic benchmark (make benchmark)
• compare MAC in constant time ( fixes bug #12 )
• add --nocache option
