- Add a set_provider_factory() method to server_state to allow
injecting provider factory which will be called when the
provider is loaded.
Other related changes:
- Implement to_string() helper method for id class.
- Fix id ostream operator human readable id printing.
- Pass victim client_service as an argument to provider::bf_abort()
to allow passing victim context to custom provider.
- Implement prev() helper method for seqno class.
- Make server_state recover_streaming_appliers_if_not_recovered()
public. In some recovery scenarios the method must be called outside
of server_state internal code paths.
- Add storage_service requires_globals() method. The storage service
implementation may override this to return false if changing to
storage service context does not require store/reset globals.
- Change view final() to also require that the view status is not
primary for the view to be final. Also change the method name to
is_final() to avoid confusion with C++ final identifier.
- Fixes to server state handling in disconnecting and disconnected
states.
- Keep TOI meta data over whole TOI critical section.

Modified tests to verify that client_service::will_replay() is
called whenever it is determined that the transaction must replay.
Added a test to verify behavior when provider::commit_order_enter()
returns BF abort error.
Moved call to client_service::will_replay() into transaction::state()
to ensure that it is always called when shift to s_must_replay
happens.
- populate and pass real error description buffer to provider in case
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
Fragment removal for SR transaction is done in transaction context
to make it atomic. However, this means that if the BF abort arrives
during fragment removal, the transaction may be rolled back inside
client_service::remove_fragments(), and client_state::after_prepare()
is left in aborted state. This case was not handled in the
post condition checks of after_prepare().
Fixed assertion in after_prepare() and implemented unit test.
Certification for commit fragments was changed to happen in
before_prepare in order to make GTID available for storage
engines in prepare phase.
Removed unused file src/wsrep-lib_test.cpp
quite useful as there might not be enough information for it
after the statement has been processed. Better to handle retrying
on DBMS side. Also removed after_statement_result enumeration and
return plain int from after_statement().
