functions are involved.
When subselect is a join with set functions and no record have been found in
it, end_send_group() sets null_row for all tables in order aggregate functions
to calculate their values correctly. Normally this null_row flag is cleared for
each table in sub_select(), but flush_cached_records() doesn't do so.
Due to this all fields from the table processed by flush_cached_records() are
always evaluated as nulls and whole select produces wrong result.
flush_cached_records() now clears null_row flag at the very beginning.

select result
Item equal objects are employed only at the optimize phase. Usually they are not
supposed to be evaluated. Yet in some cases we call the method val_int() for
them. Here we have to take care of restricting the predicate such an object
represents f1=f2= ...=fn to the projection of known fields fi1=...=fik.
Added a check for field's table being const in Item_equal::val_int().
If the field's table is not const val_int() just skips that field when
evaluating Item_equal.

When InnoDB compares varchar field in ucs2 with given key using bin collation,
it calls my_strnncollsp_ucs2_bin() to perform comparison.
Because field length was lesser than length of key field should be padded
with trailing spaces in order to get correct result.
Because my_strnncollsp_ucs2_bin() was calling my_strnncollp_ucs2_bin(), which
doesn't pads field, wrong comparison result was returned. This results in
wrong result set.

BLOB variations have number-in-bytes limit,
unlike CHAR/VARCHAR which have number-of-characters limits.
A tinyblob column can store up to 255 bytes.
In the case of basic Latin letters (which use 1 byte per character)
we can store up to 255 characters in a tinyblob column.
When passing an utf8 tinyblob column as an argument into
a function (e.g. COALESCE) we need to reserve 3*255 bytes.
I.e. multiply length in bytes to mbcharlen for the character set.
Although in reality a tinyblob column can never be 3*255 bytes long,
we need to set max_length to multiply to make fix_length_and_dec()
of the function-caller (e.g. COALESCE) calculate the correct max_length
for the column being created.

Bug#15581: COALESCE function truncates mutli-byte TINYTEXT values
BLOB variations have byte limits,
unlike CHAR/VARCHAR which have number-of-character limits.
It means tinyblob can store up to 255 bytes.
All of them can be basic latin letters which use 1 byte
per character.
I.e. we can store up to 255 characters in a tinyblob column.
When passing a tinyblob column as an argument into
a function (for example COALESCE or CONCAT) we
need to reserve 3*255 bytes in the case of utf-8.
I.e. multiply length in bytes to mbcharlen for the
character set.

impossible view security".
We should not expose names of tables which are explicitly or implicitly (via
routine or trigger) used by view even if we find that they are missing.
So during building of list of prelocked tables for statement we track which
routines (and therefore tables for these routines) are used from views. We
mark elements of LEX::routines set which correspond to routines used in views
by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST
object for topmost view which uses routine. We propagate this mark to all
routines which are used by this routine and which we add to this set. We also
mark tables used by such routine which we add to the list of tables for
prelocking as belonging to this view.

mysql-test/r/sp.result:
Test results fixed: a fix for Bug#15392
mysql-test/t/sp.test:
A test case for Bug#15392 "Server crashes during prepared
statement execute". No test case for error in
Item_func_set_user_var::update as the only possible one is OOM.
sql/sp_head.cc:
A fix for Bug#15392 "Server crashes during prepared statement
execute": the bug was caused by mysql_change_db() call
which was overwriting the error state of 'ret'.
Later in the code, suv->fix_fields() would discover
thd->net.report_error and return it without completing
its work. As the return value of fix_fields() was ignored,
the server would afterwards crash in suv->update().
The fix makes sure that a possible internal error
is raised in reset_lex_and_exec_core and then is
handled in sp_head::execute_procedure.

Changes from snapshot innodb-5.0-ss52.
Note that buf_block_t::index should be protected by btr_search_latch
or an s-latch or x-latch on the index page.
btr_search_drop_page_hash_index(): Read block->index while holding
btr_search_latch and use the cached value in the loop. Remove some
redundant assertions.
Also fix 13778. When FOREIGN_KEY_CHECKS=0 we still need to check that
datatypes between foreign key references are compatible.
Also added test cases to 9802.

The cause of the bug was the use of end_write_group instead of end_write
in the case when ORDER BY required a temporary table, which didn't take
into account the fact that loose index scan already computes the result
of MIN/MAX aggregate functions (and performs grouping).
The solution is to call end_write instead of end_write_group and to add
the MIN/MAX functions to the list of regular functions so that their
values are inserted into the temporary table.

- create_tmp_table allocates space for aggregate functions in the
list of regular functions,
- use end_write instead of end_write group,
- copy the pointers to the MIN/MAX aggregate functions to the list
of regular functions TMP_TABLE_PARAM::items_to_copy.

New parameter to create_tmp_table.
