Galera wsrep provider
Galera wsrep provider is a dlopenable generic replication library which implements the wsrep provider API. It provides very efficient synchronous replication, and multi-master and "parallel applying" capabilities for opaque data buffers. Its primary focus is data consistency. A transaction is either applied on every node, or not at all. It works anywhere TCP works, including on WAN, and can utilize UDP multicast where available. It is used by the MySQL-wsrep patch project to create true multi-master MySQL/InnoDB clusters.

Release Notes: This release fixes broken IST between 32-bit and 64-bt architectures, a possible cluster crash on arbitrator reconnect, and a number of other minor issues. It adds support for "shared" keys, a gcs.sync_donor boolean parameter to keep state donor temporally synced with the cluster (useful for non-blocking state transfers like xtrabackup and IST), and support for Solaris 11 (x86 only).
