72d135bec5 Clear field_alloc when it's moved to result set (allows us to always call free_root on field_alloc)
Change to use remove_file instead of 'system rm' in a lot of tests. (Should fix some windows test problems)
Removed memory leak in mysql_test if sync_with_master fails.
Do not terminate ndb_cluster_binary_log before the util thread has finnished. This should fix a shutdown bug where a thread is accessing injector_mutex after it's freed.
Patch may fix Bug#27622 "mysqld shutdown, util thread continues, while binlog thread exits"

e42c980967 Table definition cache, part 2
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
  object and open a handler to the table object

Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it

- For a busy system this change will give you:
 - Less memory usage for table object
 - Faster opening of tables (if it's has been in use or is in table definition cache)
 - Allow you to cache many table definitions objects
 - Faster drop of table

6f8d3c4844 A fix and a test case for Bug#6513 "Test Suite: Values inserted by using
cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql Server
Crash while fetching from table with 5 million records."
A fix for a possible memory leak when fetching into an SP cursor
in a long loop.
The patch uses a common implementation of cursors in the binary protocol and 
in stored procedures and implements materialized cursors.
For implementation details, see comments in sql_cursor.cc

Fix for PS and SELECT ... PROCEDURE
Reset all warnings when executing a new PS query
group_concat(...ORDER BY) didn't work with PS

f5d1b711c6 Implementation of Monty's idea about clear_alloc_root() optimization and cleanup of work
with memory roots in THD/Statement/Item_arena.
Added assertions preventing memory allocation on bzero'ed MEM_ROOT since it is worked by 
pure luck and was very ineffective.

e347f63192 Max open files handling moved to my_set_max_open_files()
This ensures that my_file_info takes this the max number of files into account and one can now use --open-files-limit on windows to increase number of used files up to 2048
