Post-review changes:
* modify mysqlbinlog's --help message for --rewrite-db option.
* add test for mysqlbinlog with --read-from-remote-server option.

- Apply Alexander Ivanov's fix to testsuite

- Review fixes

client/Makefile.am:
  - Make it build on Linux
client/mysqlbinlog.cc:
  - Coding style fixes
  - Better/more comments
  - Use client/sql_string.*, not server's sql/sql_string.*.
  - Don't declare a dummy TABLE_LIST structure in the client.
client/sql_string.h:
  - Use client/sql_string.*, not server's sql/sql_string.*.
sql/log_event.cc:
  = Fix coding style
  = Introduce Log_event::event_owns_temp_buf which tells whether Log_event::temp_buf is 'owned' by the Log_event object and should be my_free'd on return. 
  This is needed because rewrite_db() needs to dispose of the buffer, and 
  - when mysqlbinlog is reading directly from binlog file, the buffer 
    should be freed
  - when mysqlbinlog is reading from a server, the buffer is a part of network
    buffer and shouldn't be freed.

Merge from trunk.

Add test-suite.

Add --rewrite-db option to mysqlbinlog.

Add Rpl_filter to mysqlbinlog.cc
Note. Though within MWL#36 we are going to use only two Rpl_filter's
      methods (add_db_rewrite and get_rewrite_db), we look forward for
      MWL#40 where Rpl_filter is likely to be used to its more extent.
Note. Within MWL#36 we will not use Rpl_filter for supporting --database
      option: this option allows to specify only one database what
      doesn't correlate with Rpl_filter::add_do_db() (using this method
      will either appear "artificial" or require changing --database
      semantics). To be discussed within MWL#40.
To add Rpl_filter we need:
1. include sql_string.h
   There are two instances of sql_string.* files - in sql and in client
   directories. We need to use the ones from the sql dir.
2. include sql_list.h
   This requires to define a client version of sql_alloc() function.
3. include rpl_filter.h
   This requires a definition of system_charset_info variable.
   Besides, Rpl_filter::tables_ok() refers to a TABLE_LIST structure which
   encounts deep non-client dependencies and can't be used here as is. On
   the other hand, tables_ok() make use only few TABLE_LIST's members and
   none of them depends on specific server context. This allows to redefine
   TABLE_LIST in a client context so that tables_ok() becomes admissible
   (surely it's a kind of hack but (at least currently) it's better than
   #ifndef'ing this method in Rpl_filter definition).
Also add Rpl_filter::rewrite_db_is_empty() method. This is needed to be
able to check that --rewrite-db is not used jointly with --base64-output=
always (this is not supported - at least currently).

Add rewrite_db() member to the Table_map_log_event class.
Each RBR-event in binary log is preceded by a Table_map event
containing a (db_id, db_name) pair. The rewrite_db(new_name)
function replaces db_name by new_name in a buffer containing
Table_map event read from the binary log.

Make sql_alloc() declaration "public" for a client context.
The reason is that sql_alloc() is used in definition of some common
purpose stuff (e.g. sql_list.*). To make this stuff available for a
client context we declare sql_alloc() as a "virtual function", i.e.
as a function that is already declared but must be defined in this
context (note that definition of sql_alloc() in thr_malloc.cc is
#ifndef'ed for MYSQL_CLIENT).
Also make sql_string.h repeatedly includable.

This fixes a race condition in the test system

mysql-test/include/maria_empty_logs.inc:
  Added comment
mysql-test/include/wait_for_status_var.inc:
  Fixed type in variable name. Add ' around variables for better error message
mysql-test/mysql-test-run.pl:
  Remove -skip-falcon (not to be used), add skip-pbxt to bootstrap
mysql-test/suite/maria/t/maria_showlog_error-master.opt:
  Force restart before maria_showlog_error to get rid of status from previous connection

while waiting for output): attempt 2

Remove the run of the parts suite (as it is now included in default list of suite).
Add run of PBXT.

binary distribution zips.

Problem was the use of SHOW PROCESSLIST. This is not fully functional in
embedded server, STATE is hardcoded to "Writing to net".

Fixed using --replace_result for STATE.

The test is supposed to provoke a deadlock, to test a crash of the server in
some deadlock scenarios.

The problem is that in recent version of MySQL, no deadlock occurs. It is not
clear why a deadlock should be expected. One transaction does an insert+delete
on primary key value 1 in table t2. The other transaction does an insert on
primary key value 123. There seems no reason that these should conflict, so
there is no deadlock.

(Presumably an earlier version did get a deadlock due to maybe taking excessive
locks on the insert+delete of primary key value 1. The table has only one row,
so maybe a different locking was used ("Impossible WHERE noticed after reading
const tables"))

Fix is to have transaction 1 lock PK 1 and transaction 2 lock PK 123. Then have
transaction 2 access PK 1 (wait) and transaction 1 access PK 123 (deadlock).

It has been checked that this modified test case still crashes the server in
the same way prior to fix of the original bug (Bug#24989).


mysql-test/include/read_many_rows.inc:
  Provoke deadlock on same PK value in the two transactions to ensure that the
  deadlock does occur independently on whatever execution plan is chosen.
mysql-test/r/read_many_rows_innodb.result:
  Result file update.

Some result updates necessary due to extra tables and columns added in
information_schema in MariaDB (XtraDB, PBXT, microsec_process).

Also fix bad merge of two result files; apparently the test case was merged,
but the result file was not.

mysql-test/suite/funcs_1/datadict/processlist_priv.inc:
  Handle the new TIME_MS column in information_schema.processlist.

  Handle new tables in information_schema.
mysql-test/suite/funcs_1/r/is_tables_is.result:
  Handle new tables in information_schema.
mysql-test/suite/funcs_1/r/is_tables_myisam.result:
  Fix previous bad merge; apparently this file was not merged along with test changes.
mysql-test/suite/funcs_1/r/processlist_priv_no_prot.result:
  Handle the new TIME_MS column in information_schema.processlist.
mysql-test/suite/funcs_1/r/processlist_val_no_prot.result:
  Fix previous bad merge; apparently this file was not merged along with test changes.
  Also handle the new TIME_MS column in INFORMATION_SCHEMA.PROCESSLIST.
mysql-test/suite/funcs_1/t/is_columns_is.test:
  Since result file includes PBXT information_schema tables, we need PBXT to run this test.

The --enable_prepare_warnings allows to not discard warnings from autorepair
of crashed table in --ps-protocol mode.

Use this to properly fix the parts.partition_recover_myisam and
maria.maria-recover tests.

Add a test case for the new feature. This also adds missing test coverage
for the case where the same warning is thrown in both prepare and execute
phase.

  Implement new commands --enable-prepare_warnings and --disable_prepare_warnings.
mysql-test/r/mysqltest_ps.result:

- Include maria_chk and other maria binaries
- Include sql/$TARGET/mysqld.lib, like mainline does (but what is that useful for?)
- Don't include my_safe_{process,kill} garbage.
- call '/bin/find', not just 'find' is that is some incompatible windows command.

 - Don't need any m1 prefix for the first release based on given MySQL
   version number.

 - Fix mysql-test-run to understand that some stuff is installed under
   share/mariadb rather than share/mysql.

MBUG#442254: mysql-test-run --embedded fails on Windows with: ERROR: .opt file references 'EXAMPLE_PLUGIN_OPT'
