Test was flakey on some machines and showed spurious
reds for races.

New-and-improved test makes do with fewer statements,
no mysqltest-variables, and no backticks. Should hope-
fully be more robust. Heck, it's debatable whether we
should have a test for this, anyway.

mysql-test/suite/rpl/r/rpl_temporary.result:
  streamlined
mysql-test/suite/rpl/t/rpl_temporary.test:

It leads to crash because there is no OOM check in ha_archive::unpack_row().
The fix:
added OOM error check

compilation warning fixed

due to name_const substitution

Problem:
"In general, statements executed within a stored procedure
are written to the binary log using the same rules that
would apply were the statements to be executed in standalone
fashion. Some special care is taken when logging procedure
statements because statement execution within procedures
is not quite the same as in non-procedure context".

For example, each reference to a local variable in SP's
statements is replaced by NAME_CONST(var_name, var_value).
Queries like
"CREATE TABLE ... SELECT FUNC(local_var ..."
are logged as
"CREATE TABLE ... SELECT FUNC(NAME_CONST("local_var", var_value) ..."
that leads to differrent field names and
might result in "Incorrect column name" if var_value is long enough.

Fix: in 5.x we'll issue a warning in such a case.
In 6.0 we should get rid of NAME_CONST().

Note: this issue and change should be described in the documentation
("Binary Logging of Stored Programs").

manual merge. also adds test specific to 5.1+

Fine-tuning. Broke out comparison into method by
suggestion of Davi. Clarified comments. Reverting
test-case which I find too brittle; proper test
case in 5.1+.

(Pushing for Azundris)
      
We allow security-contexts with NULL users (for
system-threads and for unauthenticated users).
If a non-SUPER-user tried to KILL such a thread,
we tried to compare the user-fields to see whether
they owned that thread. Comparing against NULL was
not a good idea.
      
If KILLer does not have SUPER-privilege, we
specifically check whether both KILLer and KILLee
have a non-NULL user before testing for string-
equality. If either is NULL, we reject the KILL.

mysql-test/r/rpl_temporary.result:
  Try to have a non-SUPER user KILL a system thread.
mysql-test/t/rpl_temporary.test:
  Try to have a non-SUPER user KILL a system thread.
sql/sql_parse.cc:
  Make sure security contexts of both KILLer *and*
          KILLee are non-NULL before testing for string-equality!

            
The issue happened to be two-fold.
The table map event was recorded into binlog having
an incorrect size when number of columns exceeded 251. 
The Row-based event had incorrect recording and restoring m_width member within
the same as above conditions.

Fixed with correcting m_data_size and m_width.


mysql-test/suite/rpl/r/rpl_row_wide_table.result:
  the new test results.
mysql-test/suite/rpl/t/rpl_row_wide_table.test:
  regression test for bug#42977.
sql/log_event.cc:
  0. all buffers that used in net_store_length() are augmented with 1 for safety
  to be able to contain the magic and the content of ulonglong as well;
  1. Rows_log_event::get_data_size() yieled incorrect size |m_width/8| whereas 
     it should be m_width;
  2. Table_map_log_event::Table_map_log_event yieled incorrect value for
     `m_data_size' probably presuming 1-byte integer max for the column number;
sql/rpl_utility.h:
  DBUG_PRINT_BITSET() macro is left 256-cols limited but has made safe and commented.

                    expired timeout on debx86-b in PB
