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.

- Adjust CMakeLists.txt to follow latest mysql's expectations about plugins
- Add typecasts
- wrap pbms_enabled.cc in #ifdef

 - innodb-index needs regexp replace for embedded like other similar tests.

 - partitions_special_* need to be modified for the extension from 16 to 32
   max key parts allowed that was made in MariaDB.

Don't call _mi_decrement_open_count() for mi_extra(HA_EXTRA_PREPARE_FOR_DROP).
This ensures that if we empty the key cache and a drop table fails later, the index will be automaticly rebuilt

storage/maria/ma_extra.c:
  Don't call _ma_decrement_open_count() for ma_extra(HA_EXTRA_PREPARE_FOR_DROP).
  This ensures that if we empty the key cache and a drop table fails later, the index will be automaticly rebuilt
storage/maria/ma_locking.c:
  Simple optimization: Don't call maria_lock_database() if locking is disabled

  Don't call _mi_decrement_open_count() for mi_extra(HA_EXTRA_PREPARE_FOR_DROP).
  Simplify code to remove if

When DNS is not working and returns some address even for non-existing
host names, some test cases fail with wrong error.

Fix by disabling these tests on such systems.

Remove mysql-test-run.pl unnecessary and confusing 'skipped' messages.

 - In mysql-test-run.pl, we auto-generate combinations of replication
   tests. But this sometimes generates combinations that are meaningless,
   like running a test that requires row-based replication with
   statement-based. These superfluous combinationes should not be
   reported as skipped, they should just be deleted.

 - Remove ndb suites from default suites, as we do not support NDB
   in MariaDB.

Keep skip messages resulting from running mysql-test-run.pl in special
ways, eg. --mysqld=--binlog-format=statement.

- mysql_get_server_name()
  This returns MySQL or MariaDB depending on the server type

Better default prompt (shows server you are connected to and base directory)

sql/sql_plugin.cc:
  Temporary solution: skip PBXT (like we do e.g. for --skip-innodb) in embedded server, as it doesn't work there.

This allows to eg use --mem or --parallel for better performance on big boxes.

Don't ever build it, and don't include it in source tarballs.
(we keep the sources in bzr to not get conflicts on every upstream change).

This is needed to fix failures seen in Buildbot (main.ctype_gbk_binlog).
Problem is that some tests did not RESET MASTER, causing them to pick up random
binlog files depending on prior tests.

(These are by their nature difficult to test reliably due to differences in timing).

Fix trivial typo in BUILD/* scripts.

  Fix typo.
mysql-test/mysql-test-run.pl:
  Fix mysql-test-run.pl to be able to find plugins used in testing also when running the
  test suite from an installed mysqld package.
