* libfs/src/rfs/rtems-rfs-block.c: Reset a buffer handle after
moving down an indirection level.
* libfs/src/rfs/rtems-rfs-dir.c: Move directory entry validation
into a macro and use the macro. Fix the range check on the ino so
all inodes can be used.
* libfs/src/rfs/rtems-rfs-file-system.c,
libfs/src/rfs/rtems-rfs-file-system.h:: Add a version number to
the superblock. Use RTEMS_RFS_INODE_SIZE.
* libfs/src/rfs/rtems-rfs-file.c: Fix the size offset on partial
block lengths. Set the size in the file handle on a truncate to
0.
* libfs/src/rfs/rtems-rfs-format.c: Add a version number to
the superblock. Use RTEMS_RFS_INODE_SIZE. A better set of defaults
for small disks.
* libfs/src/rfs/rtems-rfs-inode.c: Use RTEMS_RFS_INODE_SIZE. Free
the allocated inode if it cannot be opened.
* libfs/src/rfs/rtems-rfs-inode.h: Add RTEMS_RFS_INODE_SIZE.
* libfs/src/rfs/rtems-rfs-rtems-file.c: Move some of the iop
acceses inside the fs lock.
* libfs/src/rfs/rtems-rfs-shell.c: Use RTEMS_RFS_INODE_SIZE.
