Wl#6314: Prepared transactions slave parallel applier
  
Description: Implemented intra-schema multi-threaded slave
MySQL replication slaves can now apply events in parallel within
the database. This is made possible by using the parallelization
information from the master. The information is stored as logical
timestamp of the last transaction that committed before the current
one, when this transaction entered the prepare phase. All the
transactions that have the same commit parent can be executed in
parallel.
