a small refinement to the test

There was auto-reconnecting by slave earlier than a prescribed by slave_net_timeout value.
The issue happened on 64bit solaris that spotted rather incorrect casting of 
the ulong slave_net_timeout into the uint of mysql.options.read_timeout.

Notice, that there is no reason for slave_net_timeout to be of type of ulong.
Since it's primarily passed as arg to mysql_options the type can be made
as uint to avoid all conversion hassles.
That's what the fixes are made.
A "side" effect of the patch is a new value for the max of slave_net_timeout
to be the max of the unsigned int type (therefore to vary across platforms).

Note, a regression test can't be made to run reliably without making it to last over some 
20 secs. That's why it is placed in suite/large_tests.

  Update old wording (table engine -> storage engine).

      
It is well-known that due to concurrency issues, a slave can become
inconsistent when a transaction contains updates to both transaction and
non-transactional tables.
                    
In a nutshell, the current code-base tries to preserve causality among the
statements by writing non-transactional statements to the txn-cache which
is flushed upon commit. However, modifications done to non-transactional
tables on behalf of a transaction become immediately visible to other
connections but may not immediately get into the binary log and therefore
consistency may be broken.
            
In general, it is impossible to automatically detect causality/dependency
among statements by just analyzing the statements sent to the server. This
happen because dependency may be hidden in the application code and it is
necessary to know a priori all the statements processed in the context of
a transaction such as in a procedure. Moreover, even for the few cases that
we could automatically address in the server, the computation effort
required could make the approach infeasible.
            
So, in this patch we introduce the option
      - "--binlog-direct-non-transactional-updates" that can be used to bypass
      the current behavior in order to write directly to binary log statements
      that change non-transactional tables.

Besides, it is used to enable the WL#2687 which is disabled by default.

in errmsg.txt. Kept the one in that matched the location
in errmsg-utf8.txt, ie after ER_UNKNOWN_LOCALE.

The reason for the crash is using uinitialized mutex attribute (MY_MUTEX_FAST_INIT)
in pthread_mutex_init.

The fix is to initialize the attribute before the first use.

Problem: The test case failed because: (i) warning text in 
         result file differed from the warning output by the 
         server, and (ii) binlog contents in result file did
         not show the statements logged wrapped in BEGIN/COMMIT
         as it is the case after WL 2687.
      
Solution: We update the result file, but first we change the
          unsafe warning text to also refer to performance_schema
          table(s). This required changing the result files for
          existing test cases that provide output for warnings 
          related to ER_BINLOG_UNSAFE_SYSTEM_TABLE. "Grepping" in
          result files, shows that only binlog_unsafe contained
          reference to such a warning.
      
          We also update the result file with the missing 
          BEGIN/COMMIT statements.
