Provider position clutters the public interface and is not
required by wsrep-API v26. Remove the position from ws_meta/view
classes and deal with it internally in custom providers.

Pass victim context for provider on BF abort
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.

Add provider position field to ws_meta and view
Provider position is needed in coordinated recovery
between application and provider. Pass the position
info from provider to application to allow making
it durable.

Fix provider loading in test for release builds
commit 6df17812d9

Introduce set_provider_factory() method for server_state
This allows injecting an application allocated provider into
server_state.
After this virtual provider getter is unnecessary. Made the getter
normal method and fixed unit tests accordingly.
Removed calls to assert() from public headers to have
full control when assertions are enabled in wsrep-lib
code regardless of parent project build configuration.
Moved methods containing assertions and non-trivial
code from headers into compilation units.
This commit defines a TLS service interface. If the implementation is
provided by the application when the provider is loaded, appropriate
hooks are probed from the provider and the provider side hooks are
initialized after the provider is loaded.
A sample implementation to demostrate the use of TLS interface
is provided in dbsim/db_tls.cpp.
Also contains a change to thread service interface: The
thread exit virtual method was changed to function pointer
to allow thread exit path which does not involve C++.
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

- Retry enter_toi() in poll_enter_toi() also for error_connection_failed
which means that the connectivity to the cluster has been lost,
a.k.a non-prim.
* Add method `restore_prepared_transaction` to `client_state` class
which restores a transaction state from storage given its xid.
* Add method `commit_or_rollback_by_xid` to terminate prepared XA
transactions by xid.
* Make sure that transactions in prepared state are not rolled back
when their master fails/partitions away.
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.
- 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
* Implemented encryption callback and enc_set_key
* Added pure virtual functions for encryption functionality
* Set enc key if provider was not loaded on time
When member joins the group and needs to receive an SST it won't
receive the corresponding menbership view event because the SST
happens after the event and will already include the effects of
all events ordered before it. The view then must be recovered from
the received state.
Minor renames and cleanups.
References codership/wsrep-lib#18
* Count separately fragments certified and fragments stored in
streaming context. Storing the fragment may ultimately fail
due to BF abort even if the fragment was succesfully certified.
Therefore we need to have separate counter for certified fragments
to determine if the transaction is streaming and seqnos of fragments
which have been succesfully stored.
* Provider release is called only after succesful fragment certification
and fragment store.
* Fixed handling of write sets with rollback flag set in apply_write_set()
* Added bootstrap service call to do DBMS side bootstrap operations
during the cluster bootstrap.
* Added last_committed_gtid() to provider interface
* Implemented wait_for_gtid() provider call
* Pass initial position to the server state
