data": remove the fix for another bug (8807) that added OUTER_REF_TABLE_BIT to all subqueries that used a placeholder to prevent their evaluation at prepare. As this bit hanged in Item_subselect::used_tables_cache for ever, a constant subquery with a placeholder was never evaluated as such, which caused wrong choice of the execution plan for the statement. - to fix Bug#8807 backport a better fix from 5.0 - post-review fixes.

and bug#8849 "problem with insert statement with table alias's": make equality propagation work in stored procedures and prepared statements. Equality propagation can change AND/OR structure of ON expressions, so the fix is to provide each execution of PS/SP with it's own copy of AND/OR tree. We have been doing that already for WHERE clauses, now ON clauses are also copied.

and blank after function name". Crop fruits of copy-paste programming: pre-caching of stored functions wasn't performed for prepared statements just because implementation of prepared statements is done as an add-on to the main execution flow, and the preload was originally implemented for main execution branch only (mysql_execute_command).

crashes server." The fix makes Item_func_rand prepared-statements aware plus it fixes the case when RAND is used in prepared statements and replication is on (as well as several similar issues). Until now we did not reset THD before every execution of a prepared statement, so if some execution had set thd->time_zone_used or thd->rand_used they would not be reset until next mysql_parse. Some of post-review fixes done.
