non-deterministic result in the test case for BUG#7947
the bug fix for BUG#7947 now fixed the result of mix_innodb_myisam_binlog test, which
in the past was missing DO RELEASE_LOCK() in the output of SHOW BINLOG EVENTS

reported in the bug have been addressed.

 ON UPDATE CASCADE

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.

kernel function to prevent CPU hogs.

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.
