This change is needed for custom provider implementations to
have a way to access the victim in the application context.
Helper interface operation_context to pass caller context for
service/provider callbacks in more type safe way.
Provider position is needed in coordinated recovery
between application and provider. Pass the position
info from provider to application to allow making
it durable.
* Added unit tests for transaction::xa_detach() and
transaction::xa_replay()
* Added unit tests for wsrep::xid
* Fixed minor issues pointed out by reviewer
which complicates diagnostics and debugging.
Don't ignore provider return codes and more verbose error logging for
sst_sent(), sst_received(), set_encryption_key() methods
Refs codership/wsrep-lib#127
- Implemented calls to enter and leave NBO phase one and two

- Changed client_state state and mode change sanity checks to
print a warning and assert() instead of throwing exceptions
to be more graceful in release builds.

of applying error
- return 0 from server_state::on_apply() if error voting confirmed
consistency
- remove fragments and rollback after fragment applying failure
- always release streaming applier on commit or rollback
