        * libfs/src/rfs/rtems-rfs-trace.c,
        libfs/src/rfs/rtems-rfs-trace.h: Add inode-delete.
        * libfs/src/rfs/rtems-rfs-shell.c: Fix formatting.
        * libfs/src/rfs/rtems-rfs-rtems-dir.c: Use ssize_t. Fix spelling.
        * libfs/src/rfs/rtems-rfs-block.c: Fix rtems_rfs_block_get_bpos to
        return the position correctly. A bpos does not have any special
        processing. Do no reset the buffer handle when shrinking
        indirectly.
        * libfs/src/rfs/rtems-rfs-inode.c: Add trace.
        * libfs/src/rfs/rtems-rfs-format.c: Fix comments.
        * libfs/src/rfs/rtems-rfs-group.c: Limit the inodes to the blocks
        in a group so the accounting works.
        * libfs/src/rfs/rtems-rfs-dir.c: PR 1705. Fix handling the offsets
        when deleting an entry.
        * libfs/src/rfs/rtems-rfs-buffer.h: Remove
        rtems_rfs_buffer_handle_reset. It is not needed and dangerous.
