- 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.

Added a wsrep::thread_service interface to allow application to
inject instrumented thread, mutex and condition variable implementation
for provider.
The interface is defined in include/wsrep/thread_service.hpp.
Sample implementation is provided in dbsim/db_threads.[h|c]pp.
This patch will also clean up some remaining dependencies to
wsrep-API compilation units so that the dependency to wsrep-API
is header only. This will extending the provider support to
later wsrep-API versions.
