New features and notable fixes in Galera replication since last binary release

* Reporting last committed write set fixed to respect commit ordering (MW-341)

* GComm socket level error handling improved to avoid backend thread exit
in case of unexpected input from ASIO IO service (GAL-518)

* Race condition fixed in GComm message sending codepath (GAL-520)

bug could stall cluster messaging until the next keepalive was sent by
some node, causing intermittent pauses in write set replication. (GAL-521)

* Code changes to avoid name collisions with FreeBSD system headers (GAL-523)
