    WL#4284: Transactional DDL locking
    
    Make transaction management more modular through a new interface.
    
    The overall objective of this change is to provide groundwork
    for the design of transactional DDL locking by cleaning up the
    transaction high level API to better distinguish operations implicit
    and explicit, and single statement transaction from operations on
    the normal transaction.
    
    Having a a high-level interface for transaction management provides
    a better base for implementing transactional concepts that are not
    always tied to storage engines and also makes it easier to interect
    with other higher level modules of the server.
    
    client/Makefile.am:
      Add new file to the build.
    libmysqld/CMakeLists.txt:
      Add new file to the build.
    libmysqld/Makefile.am:
      Add new file to the build.
    sql/CMakeLists.txt:
      Add new file to the build.
    sql/Makefile.am:
      Add new file to the build.
    sql/handler.cc:
      Remove multiplexer commit or rollback function. Most callers already
      have enough information to decided whether to rollback or commit.
      Having plain and well named functions makes it easier to read
      and understand code.
    sql/handler.h:
      Remove wrapper function as the low level transaction functions
      shouldn't be called directly anymore.
    sql/log_event.cc:
      Rename transaction management functions to the new names.
    sql/log_event_old.cc:
      Rename transaction management functions to the new names.
    sql/mysql_priv.h:
      Remove obsolete functions for implicit and explicit commit.
    sql/rpl_injector.cc:
      Rename transaction management functions to the new names.
    sql/rpl_rli.cc:
      Rename transaction management functions to the new names.
    sql/set_var.cc:
      Rename transaction management functions to the new names.
    sql/slave.cc:
      Rename transaction management functions to the new names.
    sql/sql_base.cc:
      Rename transaction management functions to the new names.
    sql/sql_class.cc:
      Rename transaction management functions to the new names.
    sql/sql_delete.cc:
      Rename transaction management functions to the new names.
    sql/sql_do.cc:
      Rename transaction management functions to the new names.
    sql/sql_insert.cc:
      Rename transaction management functions to the new names.
    sql/sql_parse.cc:
      Rename transaction management functions to the new names.
    sql/sql_partition.cc:
      Rename transaction management functions to the new names.
    sql/sql_table.cc:
      Rename transaction management functions to the new names.
    sql/transaction.cc:
      Implement wrapper functions to differentiate operations on
      the single statement transaction from the ones operating
      on the normal transaction.
    sql/transaction.h:
      Export new functions for dealing with transaction commands.
