"Server_IO_State" field

Critical error messages from get_master_version_and_clock() were written
only to the slave errorlog while Show slave status did not display any
incident happened.

Although the artifact was reported for a particular --replicate-same-server-id
related issue the fix refines all critical error reporting with 
deploying rli->report().

The test for the bug covers only --replicate-same-server-id error reporting.

t/variables.test fails on embedded server. Moved out that part again, to
a new test called t/variables-notembedded.test.

Patch to remove white-space left over after removing anonymous
namespace.

Replacing a template function with a normal static function.
The template parameter, which previously was the class to
find a binlogging function in, is now passed as a pointer to
the actual binlogging function instead.

The patch requires change of indention, but that is submitted
as a separate patch.

This is *not* a fix to the bug. I'm only disabling the failing part of
mysqldump.test until the bug is fixed. Whoever fixes it, please re-enable
the test.

mysql-test/t/variables.test, because:
 - mysql-test/suite/rpl/t/rpl_variables.test does not replicate anything,
so should not be in the rpl suite.
 - mysql-test/t/variables.test is the place for testing variable-related
problems and features.
 - I will soon commit a patch containing a test case that tests
replication of variables. It would be good if I could call the test case
mysql-test/suite/rpl/t/rpl_variables.test. I'm making place for that now.

rpl_ndb_rep_ignore
Reason: previous test, rpl_ndb_2multi_eng, does not sync slave with master
after cleanup, so tables are sometimes left on slave
Fix: sync_slave_with_master

Problem: incorrect sort order for "U+00DF SHARP S".
Fix: changing sort order for U+00DF to be equal to 's',
like the manual says.

because it uses BINLOG statement, which is not supported in embedded mode.
Fix: disable the test in embedded mode.

Problem: mysqlbinlog does not free memory if an error happens.
Fix: binlog-processing functions do not call exit() anymore. Instead, they
print an error and return an error code. Error codes are propagated all
the way back to main, and all allocated memory is freed on the way.

Documented Table_map_log_event and packed integer format. Improved
other documentation. No change outside comments.

    to leave

The artifact was caused by
a flaw in concurrent accessing the slave's io thd by
the io itself and a handling show slave status thread.
Namely, show_master_info did not acquire mi->run_lock mutex that is
specified for mi->io_thd member.

Fixed with deploying the mutex locking and unlocking. The mutex is kept
short time and without interleaving with mi->data_lock mutex.

Todo: to report and fix an issue with 
    sys_var_slave_skip_counter::{methods} 
seem to acquire incorrectly
     active_mi->rli.run_lock
instead of the specified
     active_mi->rli.data_lock

A test case is difficult to compose, so rpl_packet should continue serving
as the indicator.
