processing UNDO rows.

* [Revision #2891.1.29](https://bazaar.launchpad.net/~maria-captains/maria/5.1-release/revision/2891.1.29)
* Fixed bug that 'maria\_read\_log -a' didn't set max\_trid when reparing tables.

tree both overflow and underflow at same time.

replacing long keys with short keys and vice versa.

* Added more information to recovery log to make it easier to know from\
where log entry orginated.
* Introduced MARIA\_PAGE->org\_size that tells what the size of the page was\
in last log entry. This allows us to find out if all key changes for\
index page was logged.
* Small code cleanups:
* Introduced \_ma\_log\_key\_changes() to log crc of key page changes
* Added share->max\_index\_block\_size as max size of data one can put in\
key block (block\_size - KEYPAGE\_CHECKSUM\_SIZE)
