Between 5.0 and 5.1, the step of incrementing the global query id
changed, which broke how the profiler noticed when a new query had
started. That reset the state list and caused all but the last
five (or so) states to be thrown away.
Now, don't watch for query_id changes in the lower level.
Add a bogus state change at the end of profiling so that the last
real state change is timed.
Emit source reference for the start of the span of time instead of
the end of it.

Some status statements are set to be NULL in the server. We don't
log those, as it doesn't fit this style of profiling yet.
Rewrite the parser code to be more active and legible.
Relying on passive/lazy discovery of new queries was buggy.
Add a bogus status change before ending a profile, so that the

If a stored function that contains a drop temporary table statement
is invoked by a create temporary table of the same name may cause
a server crash. The problem is that when dropping a table no check
is done to ensure that table is not being used by some outer query
(or outer statement), potentially leaving the outer query with a
reference to a stale (freed) table.
The solution is when dropping a temporary table, always check if
the table is being used by some outer statement as a temporary
table can be dropped inside stored procedures.
The check is performed by looking at the TABLE::query_id value for
temporary tables. To simplify this check and to solve a bug related
to handling of temporary tables in prelocked mode, this patch changes
the way in which this member is used to track the fact that table is
used/unused. Now we ensure that TABLE::query_id is zero for unused
temporary tables (which means that all temporary tables which were
used by a statement should be marked as free for reuse after it's
execution has been completed).

sql/sql_base.cc:
Changed the approach to distinguishing currently unused temporary tables.
Now we ensure that such tables always have TABLE::query_id set to 0 and
use this fact to perform checks during opening and dropping of temporary
tables. This means that we have to call close_thread_tables() even for
statements which use only temporary tables. To make this call cheaper,
we re-factored close_thread_tables() to not take LOCK_open unless there
are open base tables.
sql/sql_handler.cc:
Properly close temporary tables associated with a handler.
sql/sql_insert.cc:
close_temporary_table is now merged into drop_temporary_table.

Now the condition doesn't cover all cases because close_thread_tables()
must be called even for statements that use only temporary tables.

Use drop_temporary_table which perform checks to verify if
the table is not being used. Error path problem is due to
a handler tables issue and is going to be addressed in bug

The mysql_change_user command fails to properly update the database pointer

happens on the user privilege pointer in the thread security context.
The solution is to properly reset and update the database name. Also update
the user_priv pointer so that it doesn't point to freed memory.
sql/sql_connect.cc:
After a successful call to check_user() without specifying a new
database name, the previous database thd->db) is freed but the
pointer is not updated to NULL.

This is a pre-requisite patch for the fix for Bug#12713 "Error in a stored
function called from a SELECT doesn't cause ROLLBACK of statem"
Implement review comments.
sql/mysql_priv.h:
check_for_max_user_connections() is used in one place only, make it static.
sql/mysqld.cc:
Remove net_printf_error(): a consolidation of error reporting facilities
is necessary to simplify maintenance of the query cache, the
client-server protocol, stored procedure continue handlers.
Rewrite the only place where its use is somewhat justified
(my_error() can not be used since we need to report an error for the thread
that does not exist) with my_snprintf()/net_send_error().
sql/protocol.cc:
Remove net_printf_error().
sql/protocol.h:
Remove net_printf_error().
sql/sql_connect.cc:
Remove net_printf_error(). In check_connection()/check_user()/
check_for_max_user_connections() do not write directly to the network,
but use the standard my_error() mechanism to record an error in THD.
It will be sent to the client by the caller. This was the last place
in the server that would attempt to send an error directly, mainly left
untouched by 5.0 refactoring because it is executed only during
thread startup.
sql/sql_parse.cc:
In the old code, when res was greater than 0, it contained an exact
error code, e.g. ER_OUT_OF_RESOURCES or NO SUCH DATABASE,
or ER_HANDSHAKE_ERROR. I don't know the reason why this error code was
ignored, and instead a generic ER_UNKNOWN_COM_ERROR was pushed into the
error stack, but knowing the relaxed attitude towards preserving the error
codes in the old code, I'm inclinded to think that it was a bug.
After this patch, the most specific error message is already pushed,
so calling my_message() again is useless.
If res is < 0, the error used to be already sent. This is not done
by the new code, but will be done later, in the end
of dispatch_command(). When this is done, clear_error() will be called
for us - it is in the first lines of do_command.
To sum up, this change is to remove COM_CHANGE_USER specific error handling
in favor of the standard one employed for all other COM_* commands.

The general log write function (general_log_print) uses printf style
arguments which need to be pre-processed, meaning that the all arguments
are copied to a single buffer and the problem is that the buffer size is
constant (1022 characters) but queries can be much larger then this.
The solution is to introduce a new log write function that accepts a
buffer and it's length as arguments. The function is to be used when
a formatted output is not required, which is the case for almost all
query write-to-log calls.
This is a incompatible change with respect to the log format of prepared
