Added MAX_STATEMENT_TIME user variable to automaticly kill queries after a given time limit has expired.
- Added timer functions based on pthread_cond_timedwait
- Added kill_handlerton() to signal storage engines about kill/timeout
- Added support for GRANT ... MAX_STATEMENT_TIME=#
- Copy max_statement_time to current user, if stored in mysql.user
- Added status variable max_statement_time_exceeded
- Added KILL_TIMEOUT
- Removed digest hash from performance schema tests as they change all the time.
- Updated test results that changed because of the new user variables or new fields in mysql.user
This functionallity is inspired by work done by Davi Arnaut at twitter.
Test case is copied from Davi's work.

sql/sql_table.h:
Updated prototypes
Using CREATE OR REPLACE TABLE is be identical to
DROP TABLE IF EXISTS table_name;
CREATE TABLE ...;
Except that:
* CREATE OR REPLACE is be atomic (now one can create the same table between drop and create).
* Temporary tables will not shadow the table name for the DROP as the CREATE TABLE tells us already if we are using a temporary table or not.
* If the table was locked with LOCK TABLES, the new table will be locked with the same lock after it's created.
Implementation details:
- We don't anymore open the to-be-created table during CREATE TABLE, which the original code did.
- There is no need to open a table we are planning to create. It's enough to check if the table exists or not.
- Removed some of duplicated code for CREATE IF NOT EXISTS.
- Give an error when using CREATE OR REPLACE with IF NOT EXISTS (conflicting options).
- As a side effect of the code changes, we don't anymore have to internally re-prepare prepared statements with CREATE TABLE if the table exists.
- Made one code path for all testing if log table are in use.
- Better error message if one tries to create/drop/alter a log table in use
- Added back disabled rpl_row_create_table test as it now seams to work and includes a lot of interesting tests.
- Added HA_LEX_CREATE_REPLACE to mark if we are using CREATE OR REPLACE
- Aligned CREATE OR REPLACE parsing code in sql_yacc.yy for TABLE and VIEW
- Changed interface for drop_temporary_table() to make it more reusable
- Changed Locked_tables_list::init_locked_tables() to work on the table object instead of the table list object. Before this it used a mix of both, which was not good.
- Locked_tables_list::unlock_locked_tables(THD *thd) now requires a valid thd argument. Old usage of calling this with 0 i changed to instead call Locked_tables_list::reset()
- Added functions Locked_tables_list:restore_lock() and Locked_tables_list::add_back_last_deleted_lock() to be able to easily add back a locked table to the lock list.
- Added restart_trans_for_tables() to be able to restart a transaction.
- DROP_ACL is required if one uses CREATE TABLE OR REPLACE.
- Added drop of normal and temporary tables in create_table_imp() if CREATE OR REPLACE was used.
- Added reacquiring of table locks in mysql_create_table() and mysql_create_like_table()

Changed interface for drop_temporary_table() to make it more reusable
Changed Locked_tables_list::init_locked_tables() to work on the table object instead of the table list object. Before this it used a mix of both, which was not good.
Locked_tables_list::unlock_locked_tables(THD *thd) now requires a valid thd argument. Old usage of calling this with 0 i changed to instead call Locked_tables_list::reset()
Added functions Locked_tables_list:restore_lock() and Locked_tables_list::add_back_last_deleted_lock() to be able to easily add back a locked table to the lock list.
Check for command number instead of open_strategy of CREATE TABLE was used.
Added restart_trans_for_tables() to be able to restart a transaction. This was needed in "create or replace ... select" between the drop table and the select.
sql/sql_base.h:
Added and updated function prototypes
sql/sql_class.h:
Added new prototypes to Locked_tables_list class
Added extra argument to select_create to avoid double call to eof() or send_error()
- I needed this in some edge case where the table was not created against expections.
sql/sql_db.cc:
New interface for check_if_log_table()
sql/sql_insert.cc:
Remember position to lock information so that we can reaquire table lock for LOCK TABLES + CREATE OR REPLACE TABLE SELECT. Later add back the lock by calling restore_lock().
Removed one not needed indentation level in create_table_from_items()
Ensure we don't call send_eof() or abort_result_set() twice.
sql/sql_lex.h:
Removed variable that I temporarly added in an earlier changeset
sql/sql_parse.cc:
Removed old test code (marked with QQ)
Ensure that we have open_strategy set as TABLE_LIST::OPEN_STUB in CREATE TABLE
Removed some IF NOT EXISTS code as this is now handled in create_table_table_impl().
Set OPTION_KEEP_LOGS later. This code had to be moved as the test for IF EXISTS has changed place.
DROP_ACL is required if one uses CREATE TABLE OR REPLACE.
sql/sql_partition_admin.cc:
New interface for check_if_log_table()
sql/sql_rename.cc:
New interface for check_if_log_table()
sql/sql_table.cc:
New interface for check_if_log_table()
Moved some code in mysql_rm_table() under a common test.
- Safe as temporary tables doesn't have statistics.
- !is_temporary_table(table) test was moved out from drop_temporary_table() and merged with upper level code.
- Added drop of normal and temporary tables in create_table_imp() if CREATE OR REPLACE was used.
- Added reacquiring of table locks in mysql_create_table() and mysql_create_like_table()
- In mysql_create_like_table(), restore table->open_strategy() if it was changed.
- Re-test if table was a view after opening it.
sql/sql_table.h:
New prototype for mysql_create_table_no_lock()
sql/sql_yacc.yy:
Added syntax for CREATE OR REPLACE TABLE
Reuse new code for CREATE OR REPLACE VIEW

Added name for enum type
sql/table_cache.cc:
More DBUG
support ha_innodb.so as a dynamic plugin.
* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/

* don't use tdc_size and tc_size in a module
update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply
small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream
fix XtraDB to compile on Windows (both as a static and a dynamic plugin)
disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)
storage/innobase/handler/ha_innodb.cc:
