  Changed header to GPL version 2 only

  "strict mode: inserts autogenerated auto_increment value bigger than max"
  Strict mode should fail if autoincrement value is out of range

allow handler::info to return an error code (that will be returned to the user)

   - Remove the local static var

Bad examples of usage of a string with its length fixed.
The incorrect length in the trigger file configuration descriptor
  fixed (BUG#14090).
A hook for unknown keys added to the parser to support old .TRG files.

Final patch for 5.0 for simplifying storage engine code. We now have just one set of ifdefs. I may also remove the code for creating new handlers.
May changes were to simplify storage engine setup and support for legacy call to show storage engines.

Handlerton array is now created instead of using sys_table_types_st. All storage engines can now have inits and giant ifdef's are now gone for startup. No compeltely clean yet, handlertons will next be merged with sys_table_types. Federated and archive now have real cleanup if their inits fail. 

"SELECT ... FOR UPDATE executed as consistent read inside LOCK TABLES"
Do not discard lock_type information as handler::start_stmt() may require knowledge.
(fixed by Antony)

Cleanup for handlerton structure to allow for loadable engine work. This is the first in a series of patches. 

HP-UX compiler was generating code which makes wrong conversion from double to
ulonglong which results in not using index in some cases.

Changed type cast operators odrer with which generated code makes proper 
conversion.

Removed duplicate usage of TMP_TABLE_FORCE_MYISAM by making 'options' longlong

cursors. This should fix Bug#11813 when InnoDB part is in 
(tested with a draft patch).
The idea of the patch is that if a storage engine supports
consistent read views, we open one when open a cursor,
set is as the active view when fetch from the cursor, and close
together with cursor close.

The idea of the patch
is that every cursor gets its own lock id for table level locking.
Thus cursors are protected from updates performed within the same 
connection. Additionally a list of transient (must be closed at
commit) cursors is maintained and all transient cursors are closed
when necessary. Lastly, this patch adds support for deadlock
timeouts to TLL locking when using cursors.
+ post-review fixes.

    comments,
    unused flag OPTION_INTERNAL_SUBTRANSACTIONS removed
    SELECT_ALL flag moved into this free slot.

'#pragma interface' (that comes with the #include'd header file)

Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable

  Set #pragma implementation" earlier
Many files:
  Need to include <my_global.h> before #ifdef USE_PRAGMA_IMPLEMENTATION

Added some more ifdefs for "#pragma interface"

Added option --count to mysqlshow (to show number of rows)
Fixed possible core dump in information schema

 - Remove linking of libsupc++
 - Move all local static variables to filescope

 - Remove the local static var

  - Link with libsupc++.a which contains language support functions.
    see http://gcc.gnu.org/onlinedocs/libstdc++/faq/index.html#2_5

Windows to call CreateFileMapping() with correct arguments, and
propogating the introduction of query_id_t to everywhere query ids are
passed around. (Bug #8826)

 - Moved static variables defined inside of function to file scope to avoid this linking problem on FC3

add names to handlertons
trans_need_2pc() macro

fix for binlog+autocommit+tclog
comments, style fixes

Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon)
Created Field::make_field() and made Field_num::make_field() to call this
Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead
Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer.
Renamed TABLE_SHARE->real_name to table_name
Renamed TABLE->table_name to alias
Renamed TABLE_LIST->real_name to table_name

Add support for VARCHAR with 1 or 2 length bytes
Enable VARCHAR packing in MyISAM files (previous patch didn't pack data properly)
Give error if we got problems in temporary tables during a SELECT
Don't use new table generated by ALTER TABLE if index generation fails
Fixed wrong call by range_end() (Could cause an ASSERT in debug mode)

Renamed HA_VAR_LENGTH to HA_VAR_LENGTH_PART
Renamed in all files FIELD_TYPE_STRING and FIELD_TYPE_VAR_STRING to MYSQL_TYPE_STRING and MYSQL_TYPE_VAR_STRING to make it easy to catch all possible errors
Added support for VARCHAR KEYS to heap
Removed support for ISAM
Now only long VARCHAR columns are changed to TEXT on demand (not CHAR)
Internal temporary files can now use fixed length tables if the used VARCHAR columns are short

Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

column types TIMESTAMP is NOT NULL by default, so in order to have 
TIMESTAMP column holding NULL valaues you have to specify NULL as
one of its attributes (this needed for backward compatibility).

Main changes:
Replaced TABLE::timestamp_default_now/on_update_now members with
TABLE::timestamp_auto_set_type flag which is used everywhere
for determining if we should auto-set value of TIMESTAMP field 
during this operation or not. We are also use Field_timestamp::set_time()
instead of handler::update_timestamp() in handlers.

This allows one to setup a master <-> master replication with non conflicting auto-increment series.
Cleaned up binary log code to make it easyer to add new state variables.
Added simpler 'upper level' logic for artificial events (events that should not cause cleanups on slave).
Simplified binary log handling.
Changed how auto_increment works together with to SET INSERT_ID=# to make it more predictable: Now the inserted rows in a multi-row statement are set independent of the existing rows in the table. (Before only InnoDB did this correctly)
