Allow external locking for BF aborts

Browse Source 
Added methods bf_abort() and total_order_bf_abort() which take
wsrep::unique_lock<wsrep::mutex> as argument to allow caller
to grab the mutex before attempting BF abort. The old calls
were kept for backwards compatibility and wrap the new calls
with internal locking.
