+ * Sort the log items in the transaction.
+ *
+ * The ordering constraints are defined by the inode allocation and unlink
+ * behaviour. The rules are:
+ *
+ *	1. Every item is only logged once in a given transaction. Hence it
+ *	   represents the last logged state of the item. Hence ordering is
+ *	   dependent on the order in which operations need to be performed so
+ *	   required initial conditions are always met.
+ *
+ *	2. Cancelled buffers are recorded in pass 1 in a separate table and
+ *	   there's nothing to replay from them so we can simply cull them
+ *	   from the transaction. However, we can't do that until after we've
+ *	   replayed all the other items because they may be dependent on the
+ *	   cancelled buffer and replaying the cancelled buffer can remove it
+ *	   form the cancelled buffer table. Hence they have tobe done last.
+ *
+ *	3. Inode allocation buffers must be replayed before inode items that
+ *	   read the buffer and replay changes into it.
+ *
+ *	4. Inode unlink buffers must be replayed after inode items are replayed.
+ *	   This ensures that inodes are completely flushed to the inode buffer
+ *	   in a "free" state before we remove the unlinked inode list pointer.
+ *
+ * Hence the ordering needs to be inode allocation buffers first, inode items
+ * second, inode unlink buffers third and cancelled buffers last.
+ *
+ * But there's a problem with that - we can't tell an inode allocation buffer
+ * apart from a regular buffer, so we can't separate them. We can, however,
+ * tell an inode unlink buffer from the others, and so we can separate them out
+ * from all the other buffers and move them to last.
+ *
+ * Hence, 4 lists, in order from head to tail:
+ * 	- buffer_list for all buffers except cancelled/inode unlink buffers
+ * 	- item_list for all non-buffer items
+ * 	- inode_buffer_list for inode unlink buffers
+ * 	- cancel_list for the cancelled buffers

+       for details.  YYERROR is fine as it does not invoke this
+       function.
+     - If this state is a consistent state with a default action, then
+       the only way this function was invoked is if the default action
+       is an error action.  In that case, don't check for expected
+       tokens because there are none.
+     - The only way there can be no lookahead present (in yychar) is if
+       this state is a consistent state with a default action.  Thus,
+       detecting the absence of a lookahead is sufficient to determine
+       that there is no unexpected or expected token to report.  In that
+       case, just report a simple "syntax error".
+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+     - Of course, the expected token list depends on states to have
+       correct lookahead information, and it depends on the parser not
+       to perform extra reductions after fetching a lookahead from the
+       scanner and before detecting a syntax error.  Thus, state merging
+       (from LALR or IELR) and default reductions corrupt the expected
+       token list.  However, the list is correct for canonical LR with
+       one exception: it will still contain any token that will not be
+       accepted due to an error action in a later state.
