sql/sql_lex.h:1437: warning: control reaches end of non-void function

Boolean options cause parsing failures when they are given
with prefix loose- and an argument, either in the command
line or in configuration file.

The reason was a faulty logic which forced the parsing
to throw an error when an argument of type NO_ARG was
used together with an argument which has been identified
as a key-value pair. Despite the attribute NO_ARG these
options actually take arguments if they are of type
BOOL.

"Grantor" columns' data is lost when replicating mysql.tables_priv.
Slave SQL thread used its default user ''@'' as the grantor of GRANT|REVOKE
statements executing on it.

In this patch, current user is put in query log event for all GRANT and REVOKE
statement, SQL thread uses the user in query log event as grantor.

Remove trx_t::active_trans. Split into two separate fields with distinct
responsibilities. trx_t::is_registered and trx_t::owns_prepare_mutex.
There are wrapper functions for using this fields in ha_innodb.cc. The
wrapper functions check for invariants.

Fix some formatting to conform to InnoDB guidelines.

Remove innobase_register_stmt() and innobase_register_trx_and_stmt().

Add:
trx_is_started()
trx_deregister_from_2pc()
trx_register_for_2pc()
trx_is_registered_for_2pc()
trx_owns_prepare_commit_mutex_set()
trx_has_prepare_commit_mutex()

The variable innodb_change_buffering_debug is only present in debug builds.
Hide it from the test, so that the test passes in both debug and non-debug.

These files were needed when InnoDB Plugin was maintained and distributed
separately from the MySQL 5.1 source tree. They have never been needed in
MySQL 5.5.

It is filling the error log when testing the debug version of the server.
The printout only seems to be useful when debugging a crash, not when
testing an instrumented version of the server.

Rows events were applied wrongly on the temporary table with the same name.
But rows events are generated only for base tables. As temporary
table's data never be binlogged on row mode. Normally, base table of the
same name cannot be updated if a temporary table has the same name.
But there are two cases which can generate rows events on 
the base table of same name.
      
Case1: 'CREATE TABLE ... SELECT' statement.
In mixed format, it will generate rows events if it is unsafe.
      
Case2: Drop a transactional temporary table in a transaction
       (happens only on 5.5+).
BEGIN;
DROP TEMPORARY TABLE t1;       # t1 is a InnoDB table
INSERT INTO t1 VALUES(rand()); # t1 is a MyISAM table
COMMIT;
'DROP TEMPORARY TABLE' will be put in the transaction cache and
binlogged after the rows events generated by the 'INSERT' statement.
      
After this patch, slave opens only base table when applying a rows event.

Fix assorted warnings that are generated in optimized builds.
Most of it is silencing variables that are set but unused.

This patch also introduces the MY_ASSERT_UNREACHABLE macro
which helps the compiler to deduce that a certain piece of
code is unreachable.

Fix assorted compiler warnings.

Declare DATA_MBMAXLEN with the same data type as DATA_MBMINLEN.

Rename buf_pool_watch, buf_pool_mutex, buf_pool_zip_mutex
to buf_pool->watch, buf_pool->mutex, buf_pool->zip_mutex
in comments. Refer to buf_pool->flush_list_mutex instead of
flush_list_mutex.

Remove obsolete declarations of buf_pool_mutex and buf_pool_zip_mutex.

In the fix for Bug#53916 also apply equivalent changes to CMakeLists.txt

            
For DATA_MBMINLEN(), cast the result of UNIV_EXPECT to ulint because in GCC
it returns a long causing unsigned/signed comparison warnings.

Tag or remove unused arguments and variables.

Ensure that fdatasync is properly declared as on Mac OS X, the
function is available but there is no prototype. Also, port a
fix for a warning from the InnoDB plugin over to the builtin. 

Just check for all the functions that we are going to use, not a subset
of them.
