the previous attempt broke build on Debian4.

Still two test failures to be solved: main.myisam and main.subselect.

sql/sql_base.cc:
  Replace strmov() with strnmov() to remove the possibility for buffer overflow.
sql/sql_parse.cc:
  Reject COM_FIELD_LIST with too-big table or wildcard argument.
  (libmysqlclient doesn't allow sending too long arguments anyway, but we
  need this to protect against buffer overflow exploits).

Fixed race condition in safe_process.cc which may have caused some mysqltests to be reported as failed even if they succeded.

mysql-test/lib/My/SafeProcess/safe_process.cc:
  Fixed race condition when getting a signal while calling waitpid()
  Don't send kill on killed processes
  Return different exit codes depending on how we die.

mysql-test/r/func_time.result:
  Updated result
mysql-test/t/func_time.test:
  sysdate() could be same even with one sleep(1) in between.
storage/maria/ma_loghandler.c:
  Fixed syntax error

Fixed some timing issues in test suite



mysql-test/mysql-test-run.pl:
  Added suppression of errors that comes when master is killed before slave has connect (like with rpl_udf.test)
mysql-test/suite/funcs_1/datadict/processlist_priv.inc:
  Wait for check thread to end
mysql-test/suite/pbxt/t/status.test:
  Added longer sleep to avoid timing issue
support-files/compiler_warnings.supp:
  Fixed wrong suppression

Removed random failures from test suite

mysql-test/extra/rpl_tests/rpl_insert_id_pk.test:
  Make test predicatable.
mysql-test/include/maria_empty_logs.inc:
  We can't use 'Threads_connected' for syncronization, as the 'check_warnings' thread that just quit may still be counted in 'Threads_connected'
  Now we just wait until MySQLD answers again, which should be good enough for our purposes
mysql-test/suite/binlog/r/binlog_index.result:
  Updated results file
mysql-test/suite/binlog/t/binlog_index-master.opt:
  Added option file to not get stack traces in .err file.
mysql-test/suite/binlog/t/binlog_index.test:
  Added 'flush tables' to remove warning about crashed suppression file from logs
mysql-test/suite/pbxt/r/multi_statement.result:
  Updated results
mysql-test/suite/pbxt/t/multi_statement-master.opt:
  Added options so that slow query testing makes sense
sql/events.cc:
  Don't write Event Scheduler startup message if warnings are turned off.
sql/handler.cc:
  Removed compiler warning
sql/log.cc:
  Removed compiler warning
sql/mysqld.cc:
  Added option 'test-expect-abort'; If this is set, we don't write message to log in case of 'DBUG_ABORT'.
  (Gives us smaller, easier to read log files)
sql/set_var.cc:
  Removed compiler warning
sql/slave.cc:
  Removed compiler warning
sql/sql_plugin.cc:
  Don't write warnings about disabled plugin if using --log_warnings=0
storage/xtradb/include/ut0lst.h:
  Removed compiler warning
support-files/compiler_warnings.supp:
  Supress warning from xtradb

The problem is that we can not use make_cond_for_table().
This function relies on used_tables() condition
which is not set properly for subqueries.
As result subquery is not filtered out.
The fix is to use remove_eq_conds() function instead
of make_cond_for_table() func. 'remove_eq_conds()'
algorithm relies on const_item() value and it allows
to handle subqueries in right way.


mysql-test/r/having.result:
  test case
mysql-test/t/having.test:
  test case
sql/sql_select.cc:
  The fix is to use remove_eq_conds() function instead
  of make_cond_for_table() function.

            Procedure, while DECIMAL works

Selecting of the CONCAT(...<SP variable>...) result into
a user variable may return wrong data.


Item_func_concat::val_str contains a number of memory
allocation-saving tricks. One of them concatenates
strings inplace inserting the value of one string
at the beginning of the other string. However,
this trick didn't care about strings those points
to the same data buffer: this is possible when
a CONCAT() parameter is a stored procedure variable -
Item_sp_variable::val_str() uses the intermediate
Item_sp_variable::str_value field, where it may
store a reference to an external buffer.


The Item_func_concat::val_str function has been
modified to take into account val_str functions
(such as Item_sp_variable::val_str) that return
a pointer to an internal Item member variable
that may reference to a buffer provided.


mysql-test/r/func_concat.result:
  Test case for the bug #40625.
mysql-test/t/func_concat.test:
  Test case for the bug #40625.
sql/item_strfunc.cc:
  Bug #40625: Concat fails on DOUBLE values in a Stored
              Procedure, while DECIMAL works
  
  The Item_func_concat::val_str function has been
  modified to take into account val_str functions
  (such as Item_sp_variable::val_str) that return
  a pointer to an internal Item member variable
  that may reference to a buffer provided.

       on index

'my_decimal' class has two members which can be used to access the 
value. The member variable buf (inherited from parent class decimal_t) 
is set to member variable buffer so that both are pointing to same value.

Item_copy_decimal::copy() uses memcpy to clone 'my_decimal'. The member
buffer is declared as an array and memcpy results in copying the values
of the array, but the inherited member buf, which should be pointing at
the begining of the array 'buffer' starts pointing to the begining of 
buffer in original object (which is being cloned). Further updates on 
'my_decimal' updates only the inherited member 'buf' but leaves 
buffer unchanged.

Later when the new object (which now holds a inconsistent value) is cloned
again using proper cloning function 'my_decimal2decimal' the buf pointer
is fixed resulting in loss of the current value.

Using my_decimal2decimal instead of memcpy in Item_copy_decimal::copy()
fixed this problem.


mysql-test/r/subselect.result:
  Updated result file after addding test case for bug#47904.
mysql-test/t/subselect.test:
  Added test case for bug#47904.
sql/item.cc:
  Memcopy shouldn't be used to clone my_decimal. Use my_decimal2decimal
  instead.

            data and index files

It was possible if DATA/INDEX DIRECTORY is pointing to
symlinked MySQL data home directory.

Do not allow to drop data/index files implicitly symlinked
to data home directory. For such tables remove symlink only.

mysql-test/r/symlink.result:
  A test case for BUG#40980.
mysql-test/t/symlink.test:
  A test case for BUG#40980.
storage/myisam/mi_delete_table.c:
  Do not allow to drop data/index files implicitly symlinked
  to data home directory. For such tables remove symlink only.
