Merging with MySQL 5.1.31 and 5.1.32 Releases

Our MySQL integration code (wsrep: https://launchpad.net/codership-mysql) was lagging behind from MySQL 5.1 release cycle and we needed to catch up eventually. MySQL/Galera Demo-1 was built on top of MySQL 5.1.30 and since then both 5.1.31 and 5.1.32 have been published.

We decided to wait for 5.1.32 release before shipping out MySQL/Galera Demo-2 and this took longer than we expected. We get MySQL source code from launchpad project: https://launchpad.net/mysql-server. There, 5.1.32 release candidate was cloned to release testing at Feb 11. The 5.1.32 release was finally announced at Mar 2, but the release build was merged back to lauchpad not earlier than at Mar 7. And we had to wait for launchpad update before our merging could happen.

Fortunately, wsrep merging was simple for both releases. We have now Demo-2 RC and will run a number of tests to see if it is fit for publishing. One major problem (https://bugs.launchpad.net/codership-mysql/+bug/340148) was observed in first test round. This issue is now fixed, and the test goes on...
