f631b361b6 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

sql/sql_base.cc:
  Main implementation of table definition cache
  (The #ifdef's are there for the future when table definition cache will replace open table cache)
  Now table definitions are cached indepndent of open tables, which will speed up things when a table is in use at once from several places
  Views are not yet cached; For the moment we only cache if a table is a view or not.
  
  Faster implementation of find_temorary_table()
  Replace 'wait_for_refresh()' with the more general function 'wait_for_condition()'
  Drop table is slightly faster as we can use the table definition cache to know the type of the table

sql/table.cc:
  Creation and destruct of TABLE_SHARE objects that are common for many TABLE objects
  
  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
  
  open_table_def() is written in such a way that it should be trival to add parsing of the .frm files in new formats
sql/table.h:
  TABLE objects for the same database table now share a common TABLE_SHARE object
  In TABLE_SHARE the most common strings are now LEX_STRING's
sql/unireg.cc:
  Changed arguments to rea_create_table() to have same order as other functions
  Call field->init(table) for new created fields
sql/unireg.h:
  Added OPEN_VIEW
strings/strxnmov.c:
  Change strxnmov() to always add end \0
  This makes usage of strxnmov() safer as most of MySQL code assumes that strxnmov() will create a null terminated string

5792c4d162 Fix bug #11934 Two sequential FLUSH TABLES WITH READ LOCK hangs client 
Bug was introduced by cset 1.1659.14.1. Before it server was silently
ignoring that lock can't be acquired because it already acquired.

This patch makes make_global_read_lock_block_commit() return without error
if lock already acquired.

697cb7b106 BUG#4286 - HANDLER tables are closed by FLUSH TABLE(S). 
BUG#4335 - one name can be handler open'ed many times.
Reworked the HANDLER functions and interface.
Using a HASH to store information on open tables that
survives FLUSH TABLE.

is allowed in 4.0 to qualify them with the database name
of the base table.

8f6664c59a bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock. 
Redesigned the handler close functions so that they are usable
at different places where waiting for closing tables is done.


mysql-test/r/flush_table.result:
  bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
  Added the test results.
mysql-test/t/flush_table.test:
  bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
  Activated old test case.
  Added new test cases.
sql/mysql_priv.h:
  bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
  Made mysql_ha_close() more flexible.
  Removed mysql_ha_closeall(), which closed only one table despite its name.
  Added mysql_ha_close_list(), which closes the complete list or all tables and does not lock.
  Removed a duplicate declaration.
sql/sql_base.cc:
  bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
  Added proper close calls before some wait points to avoid deadlocks
  or infinite loops.
sql/sql_handler.cc:
  bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
  Redesigned the internal function find_table_ptr_by_name().
  It can now suppress locking and tells if the requested table
  has been flushed by itself.
  Extended mysql_ha_close() so that it can now suppres locking
  and error reporting. That way it can be used at more places and the
  old function mysql_ha_closeall() is now obsolete.
  Added a new function mysql_ha_close_list() which closes a whole list
  of HANDLER tables or all HANDLER tables, if the list is NULL.
  Furthermore is can close all 'old' (marked for flush) HANDLER tables.
sql/sql_table.cc:
  bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
  Replaced the obsolte mysql_ha_closeall() by the new mysql_ha_close().
