message:
WL#4284: Transactional DDL locking

SQL statements' effect on transactions.

Currently the MySQL server and its storage engines are not
capable of rolling back operations that define or modify data
structures (also known as DDL statements) or operations that
alter any of the system tables (the mysql database). Allowing
these group of statements to participate in transactions
is unfeasible at this time (since rollback has no effect
whatsoever on them) and goes against the design of our metadata
locking subsystem.

The solution is to issue implicit commits before and after
those statements execution. This effectively confines each of
those statements to its own special transaction and ensures
that metadata locks taken during this special transaction
are not leaked into posterior statements/transactions.


mysql-test/include/commit.inc:
  Alter table rename was not committing the normal transaction at the
  end of its execution, and as a consequence, the commit was being
  issued in the next DDL command (rename table) that happened to end
  the active transaction. Other changes are to take into account the
  implicit commits issued before and after the DDL command execution.
mysql-test/include/implicit_commit_helper.inc:
  Add auxiliary test that shows if a statement issued a 
  implicit commit.
mysql-test/r/commit_1innodb.result:
  
  Update test case result.
mysql-test/r/implicit_commit.result:
  Test implicit commit behavior of some SQL commands.
mysql-test/t/implicit_commit.test:
  Test implicit commit behavior of some SQL commands.
sql/events.cc:
  Transaction is now ended before the command execution.
sql/mysql_priv.h:
  Add flags array for server commands and remove historical 
  left over.
sql/sql_class.h:
  Add flags to control when to issue implicit commits before and
  after a command execution.
sql/sql_delete.cc:
  A implicit commit is issued at the end of truncate
  statements.
sql/sql_parse.cc:
  Mark commands that need implicit commits before and
  after their executions. The implicit commits of the
  statement and the normal transaction are now issued
  regardless of the user access privileges.
sql/sql_table.cc:
  A implicit commit is now issued before admin commands.
tests/mysql_client_test.c:
  Test that COM_REFRESH issues a implicit commit.
