Added cases for bugs #6307 and #6460.
sql_select.cc:
Fixed the problem of bug reports #6307 and #6460.
The reported wrong result sets were due to the fact that
the added call of the fix_fields method for the built
AND condition that joined WHERE and ON conditions
broke ON expression, as it removed extra AND levels
in the built condition.
It looks like that no attributes of the built condition
are needed, so we don't have to call fix_fields here.

move some code around, use set_n_backup calls instead of by-hand
setup.
FOUND is not a reserved keyword anymore
Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted
Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT

Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted
The problem is that if you compare a string field to a binary string, you can't replace the field with a string constant as the binary comparison may then fail (The original field value may be in a different case)

- Changed name resolution for GROUP BY so that derived columns do not shadow table columns
from the FROM clause. As a result GROUP BY now is handled as a true ANSI extentsion.
- Issue a warning when HAVING is resolved into ambiguous columns, and prefer the columns from
the GROUP BY clause over SELECT columns.
mysql-test/r/having.result:
Correct result for updated GROUP BY name resolution.
sql/item.cc:
- prefer GROUP columns, but if none is found use SELECT list
- issue a waring when a field may be resolved ambiguously
- more/fixed comments
sql/mysql_priv.h:
More flexible find_field_in_tables().
sql/sp.cc:

sql/sql_base.cc:
More flexible find_field_in_tables().
sql/sql_help.cc:
More flexible find_field_in_tables().
sql/sql_select.cc:
- name resolution of GROUP/ORDER BY column references is differentiated:
- GROUP BY is resolved in SELECT and FROM clauses
- ORDER BY is resolved only in SELECT (as before)
- more informative variable names
- more comments
- Changed name resolution for GROUP BY so that derived columns do not shadow table columns
from the FROM clause. As a result GROUP BY now is handled as a true ANSI extentsion.

Removed argument 'parent_alloc' from QUICK_RANGE_SELECT as this was not used
Added assert if using QUICK_GROUP_MIN_MAX_SELECT with parent_alloc as the init() function can't handle this
Changed back get_quick_select_for_ref() to use it's own alloc root becasue this function may be called several times for one query
sql/sql_handler.cc:
merge with 4.1
change variable 'err' to 'error' as same function had a label named 'err'

Use multi-update code from 5.0 instead of 4.1
We will fix the locking code shortly in 5.0 to be faster than in 4.1

crashes server (prepared statements)": the bug was that all boolean
items always recovered its original arguments at statement cleanup
stage.
This collided with Item_subselect::select_transformer, which tries to
permanently change the item tree to use a transformed subselect instead of
original one.
So we had this call sequence for prepare:
mysql_stmt_prepare -> JOIN::prepare ->
Item_subselect::fix_fields -> the item tree gets transformed ->
Item_bool_rowready_func2::cleanup, item tree is recovered to original
state, while it shouldn't have been;
mysql_stmt_execute -> attempts to execute a broken tree -> crash.
Now instead of bluntly recovering all arguments of bool functions in
Item_bool_rowready_func2::cleanup, we recover only those
which were changed, and do it in one place.
There still would exist a possibility for a collision with subselect
tranformation, if permanent and temporary changes were performed at the
same stage.
But fortunately subselect transformation is always done first, so it
doesn't conflict with the optimization done by propogate_cond_constants.
Now we have:
mysql_stmt_prepare -> JOIN::prepare -> subselect transformation
permanently changes the tree -> cleanup doesn't recover anything,
because nothing was registered for recovery.
mysql_stmt_execute -> JOIN::prepare (the tree is already transformed,
so it doesn't change), JOIN::optimize ->
propogate_cond_constants -> temporary changes the item tree
with constants -> JOIN::execute -> cleanup ->
the changes done by propogate_cond_constants are recovered, as
they were registered for recovery.

sql/item.cc:
resolve_const_item is now responsible to register all changes of the
item tree for recovery
sql/item.h:
resolve_const_item signagture changed
sql/item_cmpfunc.h:
Arguments of boolean functions are now recovered using the
centralized registry of THD.
sql/sql_class.cc:
It's crucial to add new items to the beginning of the recovery list,
so that the recovery is performed in LIFO mode: otherwise if we
change one node of a tree twice, it will be recovered to some intermediate
state.
sql/sql_select.cc:
change_cond_ref_to_const and propogate_cond_constants are now responsible
to register all changes of the item tree for recovery.
The recovery is done using the centralized THD registry of
changed tree items.
crashes server (prepared statements)": the bug was that all boolean
items always recovered its original arguments at statement cleanup
stage.
This collided with Item_subselect::select_transformer, which tries to
permanently change the item tree to use a transformed subselect instead of
original one.
So we had this call sequence for prepare:
mysql_stmt_prepare -> JOIN::prepare ->
Item_subselect::fix_fields -> the item tree gets transformed ->
Item_bool_rowready_func2::cleanup, item tree is recovered to original
state, while it shouldn't have been;
mysql_stmt_execute -> attempts to execute a broken tree -> crash.
Now instead of bluntly recovering all arguments of bool functions in
Item_bool_rowready_func2::cleanup, we recover only those
which were changed, and do it in one place.
