Moved, renamed, and deleted files

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

- * lmLogInit(), lmLogShutdown(), and logRedo() to record status
- * of the log but is not otherwise used during normal processing.
- * blocks 2 - (N-1) are used to contain log records.
- *
- * when a volume group is varied-on-line, logRedo() must have
- * been executed before the file systems (logical volumes) in

- *	log logical page
- *
- * (this comment should be rewritten !)
- * the header and trailer structures (h,t) will normally have
- * the same page and eor value.
- * An exception to this occurs when a complete page write is not
- * accomplished on a power failure. Since the hardware may "split write"
- * sectors in the page, any out of order sequence may occur during powerfail
- * and needs to be recognized during log replay.  The xor value is
- * an "exclusive or" of all log words in the page up to eor.  This
- * 32 bit eor is stored with the top 16 bits in the header and the
- * bottom 16 bits in the trailer.  logredo can easily recognize pages
- * that were not completed by reconstructing this eor and checking
- * the log page.
- *
- * Previous versions of the operating system did not allow split
- * writes and detected partially written records in logredo by
- * ordering the updates to the header, trailer, and the move of data
- * into the logdata area.  The order: (1) data is moved (2) header
- * is updated (3) trailer is updated.  In logredo, when the header
- * differed from the trailer, the header and trailer were reconciled
- * as follows: if h.page != t.page they were set to the smaller of
- * the two and h.eor and t.eor set to 8 (i.e. empty page). if (only)
- * h.eor != t.eor they were set to the smaller of their two values.

- *	log record
- *
- * (this comment should be rewritten !)
- * jfs uses only "after" log records (only a single writer is allowed
- * in a page, pages are written to temporary paging space if
- * if they must be written to disk before commit, and i/o is
- * scheduled for modified pages to their home location after
- * the log records containing the after values and the commit
- * record is written to the log on disk, undo discards the copy
- * in main-memory.)
- *
- * a log record consists of a data area of variable length followed by
- * a descriptor of fixed size LOGRDSIZE bytes.
- * the data area is rounded up to an integral number of 4-bytes and
- * must be no longer than LOGPSIZE.
- * the descriptor is of size of multiple of 4-bytes and aligned on a
- * 4-byte boundary.
- * records are packed one after the other in the data area of log pages.
- * (sometimes a DUMMY record is inserted so that at least one record ends
- * on every page or the longest record is placed on at most two pages).
- * the field eor in page header/trailer points to the byte following
- * the last record on a page.
