collation
By default constant strings in second parameter of date_time() have case
insensitive collation. Because of this expressions date_format(f,'%m') and
date_format(f,'%M') wrongly becomes equal, which results in choosing wrong
column to sort by.
Now if second parameter of date_format() is constant then it's collation is
changed to case sensitive.
sql/item_timefunc.cc:
Fix bug #14016 date_format() 2nd parameter was compared using case insensitive collation.
If second parameter of date_format() is constant then it's collation is changed to case sensitive.

object now.
sql/item_timefunc.cc:
Fixed bugs #12963, #13000: wrong VIEW creation with DAYNAME(),
DAYOFWEEK(), and WEEKDAY().

not be considered now to be Item_func_to_days object.
sql/item_timefunc.h:
Fixed bugs #12963, 13000: wrong VIEW creation with DAYNAME(),
DAYOFWEEK(), and WEEKDAY.

Ensure that we do a proper restore in case of error

Both Item_func_add_time/Item_func_timediff::val_str() now use
calc_time_diff() function which was backported from 5.0 (and which
was was fixed to properly handle microseconds part of its second
argument). Also now we correctly set sign of result in case when
first argument is negative and second is positive.

mysql-test/t/func_sapdb.test:

sql/item_timefunc.cc:
- Backported calc_time_diff() function from 5.0 tree. Changed it to
accept time value as its second argument when its first argument
is datetime value. Fixed wrong handling of microsecond part of
second argument.
- Item_func_add_time::val_str()/Item_func_timediff::val_str()
Removed similar pieces of code calculating difference
between two datetime values (or their sum) in microseconds.
Now we use calc_time_diff() function instead.
Also now we correctly set sign of result in case when first
argument is negative and second is positive.

does not work well together". Now using simplier and more correct
implementation of st_lex::unlink_first_table()/link_first_table_back()
(It also nicely handles case when global table list is created because
of implictly used time zone tables). (2nd attempt)
Fix for bug #7705 "CONVERT_TZ() crashes with subquery/WHERE on index
column". Implemented new approach for caching objects for constant
time zone arguments. Now instead of determining whenever these arguments
are constants and performing time zone lookup at fix_fields() stage, we
do it on first get_date() invocation.
Cleanup of global @@time_zone variable handling.
mysql-test/r/timezone2.result:
Added test for bugs #7705 "CONVERT_TZ() crashes with subquery/WHERE on
index column" and #7899 "CREATE TABLE .. SELECT .. and CONVERT_TZ()
function does not work well together".
mysql-test/t/timezone2.test:

sql/item_timefunc.cc:
Item_func_convert_tz():
New approach for caching objects for constant time zone arguments.
Now instead of determining whenever these arguments are constants
and performing time zone lookup at fix_fields() stage, we do it
on first get_date() invocation. This works better in cases when
const_item() for these arguments returns true only on get_date()
stage but not on fix_fields() stage (e.g. this happens in quries
with joins or derived tables).
sql/item_timefunc.h:
Item_func_convert_tz():
Added from_tz_cached/to_tz_cached members indicating whenever we
already have Time_zone object representing one of constant time zone
arguments.
sql/set_var.cc:
Cleaned up global @@time_zone variable handling. Now we use proper
locking when we are setting or reading its value.
sql/set_var.h:
Removed declaration of sys_var_thd_time_zone::get_tz_ptr() method, which
no longer used.
sql/sql_lex.cc:
st_lex::unlink_first_table(), st_lex::link_first_table_back():
Simplify implementation according to Monty's suggestion.
Instead doing something special if global and local table lists
are the same, we simply save/restore pointers to first elements
of both global and local lists (which works even when this lists
are the same!). This handles nicely the case when we have separate
global table list becuase time zone tables are implicitly used.
sql/tztime.cc:
Backport of Monty's fixes from 5.0, which give us nicer error messages
if we haven't found time zone with such name or its description.
