Server crashed in some cases when a query required a MIN/MAX
agrregation for a 'ucs2' field.
In these cases the aggregation caused calls of the function
update_tmptable_sum_func that indirectly invoked
the method Item_sum_hybrid::min_max_update_str_field()
containing a call to strip_sp for a ucs2 character set.
The latter led directly to the crash as it used my_isspace
undefined for the ucs2 character set.
Actually the call of strip_sp is not needed at all in this
situation and has been removed by the fix.

This bug in Field_string::cmp resulted in a wrong comparison
with keys in partial indexes over multi-byte character fields.
Given field a is declared as a varchar(16) collate utf8_unicode_ci
INDEX(a(4)) gives us an example of such an index.
Wrong key comparisons could lead to wrong result sets if
the selected query execution plan used a range scan by
a partial index over a utf8 character field.
This also caused wrong results in many other cases.

Using MAX()/MIN() on table with disabled indexes (by ALTER TABLE)
results in error 124 (wrong index) from storage engine.
The problem was that optimizer use disabled index to optimize
MAX()/MIN(). Normally it must skip disabled index and perform
table scan.
This patch skips disabled indexes for min/max optimization.

The function check_one_table_access() called to check access to tables in
SELECT/INSERT/UPDATE was doing additional checks/modifications that don't hold
in the context of setup_tables_and_check_access().
That's why the check_one_table() was split into two : the functionality needed by
setup_tables_and_check_access() into check_single_table_access() and the rest of
the functionality stays in check_one_table_access() that is made to call the new
check_single_table_access() function.

Fixes bug#17264, for alter table on win32 for successfull operation completion
it is used TL_WRITE(=10) lock instead of TL_WRITE_ALLOW_READ(=6), however here
in innodb handler TL_WRTIE is lifted to TL_WRITE_ALLOW_WRITE, which causes
race condition when several clients do alter table simultaneously.

for the join.
Removed the redundant re-initialization of the context, because

tables
Currently in INSERT ... SELECT ... LIMIT ... the compiler uses a
temporary table to store the results of SELECT ... LIMIT .. and then
uses that table as a source for INSERT. The problem is that in some cases
it actually skips the LIMIT clause in doing that and materializes the
whole SELECT result set regardless of the LIMIT.
This fix is limiting the process of filling up the temp table with only
that much rows that will be actually used by propagating the LIMIT value.

grouping
Certain updates of table joined to self results in unexpected
behavior.
The problem was that record cache was mistakenly enabled for
self-joined table updates. Normally record cache must be disabled
for such updates.
Fixed wrong condition in code that determines whether to use
record cache for self-joined table updates.
Only MyISAM tables were affected.
