Added a test case for bug #10124.
sql_select.h, item_subselect.cc, sql_select.cc:
  Fixed bug #10124.
  The copy method of the store_key classes can return
  STORE_KEY_OK=0, STORE_KEY_FATAL=1, STORE_KEY_CONV=2 now.
field.cc:
  Fixed bug #10124.
  When ussuing a warning the store methods return 2 instead of 1 now.

Fix GCC 4.0 link failure.
Better CXX_VERSION guessing.

Fix for yaSSL link failures with Forte Developer 7, MIPSpro Compilers, Compaq C++.
These compilers have problem with implicit template instantiation in archives
(libyassl.a, libtaocrypt.a). Instantiate templates explicitly.

Fix for yaSSL link failure on powermacg5 (gcc 3.3). When -O3 is specified gcc inlines
__cxa_pure_virtual. This is wrong behavior, __cxa_pure_virtual must never be inlined.

  Added test case for bug #11283.
field.h, field.cc:
  Fixed bug #11283: wrong conversion from varchar to decimal.
  Added methods Field_string::val_decimal,
  Field_varstring::val_decimal, Field_blob::val_decimal.
  They are not inherited from the base class Field_longstr
  anymore.

'#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

  adding test
field.cc:
  bug#10714 Inserting double value into utf8 column crashes server:
  sprintf was executed with too big length, which caused
  crash on some Windows platforms.

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

Added some more ifdefs for "#pragma interface"

a fix (bug #10539: When inserting out of range value in BIT, different engines behaves differently).           

Mostly about precision/decimals of the results of the operations

return error. We'll use it for better warnign reporting.

minor cleanups
XA tests

CAST() now produces warnings when casting a wrong INTEGER or CHAR values. This also applies to implicite string to number casts. (Bug #5912)
ALTER TABLE now fails in STRICT mode if it generates warnings.
Inserting a zero date in a DATE, DATETIME or TIMESTAMP column during TRADITIONAL mode now produces an error. (Bug #5933)

Fixed that datetime gives warning for zero dates in traditional mode

Small fixes while doing review of new pushed code
More test cases for decimal

Fixed Field_timestamp::val_int() so now it works correctly in --new mode
(or for TIMESTAMP(19) columns). 
Also removed unused Field_timestamp::fill_and_store() method.

fixed my_charpos() call in Field_varstring::get_key_image

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

  don't call escape_string_for_mysql() unnecesary
  don't overwrite local buffer
escape_string_for_mysql():
  take a length of the destination buffer as an argument

Removed some optional arguments
Fixed portability problem in federated tests

 implementation of AVG(DISTINCT) which utilizes the approach with Fields.
The patch implemented in October is portede to the up-to-date tree 
containing DECIMAL type.
Tests for AVG(DISTINCT) (although there is not much to test provided
that SUM(DISTINCT) works), cleanups for COUNT(DISTINCT) and GROUP_CONCAT()
will follow in another changeset.

(Found during build process)

Change string->float conversion to delay division as long as possible.
This gives us more exact integer->float conversion for numbers of type '123.45E+02' (Bug #7740)

  optimize test_if_minus() when not UCS2 support is compiled.
