Modified RN291: Fixed bug #489088, I use plugin_unlock to remove the reference from the THD, as it is not required

Added 'mariadb_SERVER' as extra config group for MariaDB embedded server


client/mysql.cc:
  Cleanup
  Added 'mariadb_SERVER' as extra config group for MariaDB embedded server
mysys/thr_mutex.c:
  Fixed LPBUG#485443 --with-fast-mutexes and without safe mutexes (debug build) maria do not builds

Safety change to ensure read/black trees (used with heap tables) works on 64 bit setups where ulong <> size_t
Don't retry test cases by default
Fixed bug where we could (under unlikely error conditions) access not initialized variable

include/my_tree.h:
  Safety change to ensure read/black trees (used with heap tables) works on 64 bit setups where ulong <> size_t
  (Pointed out by Bryan Aker)
mysql-test/mysql-test-run.pl:
  Don't retry test cases by default
  This makes it too easy to miss failures and we have anyway to fix race conditions, not ignore them.
mysys/tree.c:
  Safety change to ensure read/black trees (used with heap tables) works on 64 bit setups where ulong <> size_t
sql/sql_delete.cc:
  Fixed bug where we could (under unlikely error conditions) access not initialized variable.
  (Pointed out by Bryan Aker)

This eliminates a warning from Automake about the double declaration.

mysys/my_seek.c:
  Give error if MY_WME is used
sql/sql_insert.cc:
  Fixed compiler warning
storage/maria/ha_maria.cc:
  Changed driver of Maria storage engine project

Some files are in different locations in this case.

storage/federatedx/CMakeLists.txt:
  Add fedrated files for build

storage/federatedx/ha_federatedx.cc:
  lower_case_file_system do not suported for windows dll

storage/federatedx/CMakeLists.txt:
  removed the same goals for federated and federatedx

sql/sql_show.cc:
  Change decimal item to type holder, to be able to define the decimals and max_length for the DECIMAL
  field from the schema specification instead of the value of the item.

Fixed by renaming a file and editing the typo in Makefile.am

sql/mysqld.cc:
  Explicit type casting required by windows x64 compiler.
storage/xtradb/include/srv0srv.h:
  Parameters should be declared as ulong.
storage/xtradb/srv/srv0srv.c:
  Parameters should be declared as ulong.

Also missing copyright for copied macros.
Fix by Antony Curtis.
