Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- *   Returns 32-bit word starting at byte pointed to by @miter@
- *   handling any alignment issues.  Bytes past the buffer's end
- *   are not accessed (read) but are returned as zeroes.  @miter@
- *   is advanced by 4 bytes or to the end of buffer whichever is
- *   closer.
- *
- * Context:
- *   Same requirements as in sg_miter_next().
- *
- * Returns:
- *   32-bit word just read.
