The bug report revealed two problems related to min/max optimization:
1. If the length of a constant key used in a SARGable condition for
for the MIN/MAX fields is greater than the length of the field an
unwanted warning on key truncation is issued;
2. If MIN/MAX optimization is applied to a partial index, like INDEX(b(4))
than can lead to returning a wrong result set.
mysql-test/r/func_group.result:
Added test cases for bug #18206.
mysql-test/t/func_group.test:

sql/opt_sum.cc:
Fixed bug #18206.
Suppressed the warning about data truncation when store_val_in_field
was used to store keys for the field used in MIN/MAX optimization.
Blocked MIN/MAX optimization for partial keys, such as in INDEX(b(4)).

Fixed bug #18206.
Added a parameter for the function store_val_in_field allowing to
control setting warnings about data truncation in the function.

sql/sql_class.cc:

sql/sql_select.cc:
Allocation of tmp_join fixed to involve constructor (it is not related to the bug directly but might cause other problems).
Excluded posibility of tmp_table_param.copy_field double deletion (BUG#14851).
sql/sql_select.h:
JOINs constructor added, initialization of them fixed (it is not related to the bug directly but might cause other problems).
Procedure analyse() redefines select's fields_list. setup_copy_fields() assumes
that fields_list is a part of all_fields_list. Because select have only
3 columns and analyse() redefines it to have 10 columns, int overrun in
setup_copy_fields() occurs and server goes to almost infinite loop.
Because fields_list used not only to send data ad fields types, it's wrong
to allow procedure redefine it. This patch separates select's fileds_list
and procedure's one. Now if procedure is present, copy of fields_list is
created in procedure_fields_list and it is used for sending data and fields.

Test case for bug #14138 ROLLUP and PROCEDURE ANALYSE() hang server
mysql-test/r/analyse.result:
Test case for bug #14138 ROLLUP and PROCEDURE ANALYSE() hang server
sql/sql_select.h:
Fix bug #14138 ROLLUP and PROCEDURE ANALYSE() hang server
To JOIN Added separate fields_list for procedure.
sql/sql_select.cc:
Fix bug #14138 ROLLUP and PROCEDURE ANALYSE() hang server
SELECT's fields_list and procedure's fields_list made split. If procedure is defined
then procedure's fields_list is used to send fields and data.
Date field was declared as not null, thus expression 'datefield is null'
was always false. For SELECT special handling of such cases is used.
There 'datefield is null' converted to 'datefield eq "0000-00-00"'.
In mysql_update() before creation of select added remove_eq_conds() call.
It makes some optimization of conds and in particular performs conversion
from 'is null' to 'eq'.
Also remove_eq_conds() makes some evaluation of conds and if it founds that
conds is always false then update statement is not processed further.
All this allows to perform some update statements process faster due to
optimized conds, and not wasting resources if conds known to be false.
sql/sql_select.cc:
Fix bug#14186 select datefield is null not updated
Remove static from remove_eq_conds()
sql/sql_select.h:
Fix bug#14186 select datefield is null not updated

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
