on subquery inside a SP
Problem: repeated call of a SP containing an incorrect query with a
subselect may lead to failed ASSERT().
Fix: set proper sublelect's state in case of error occured during
subquery transformation.

Fix for bug#46629: Item_in_subselect::val_int(): Assertion `0'
on subquery inside a SP
- don't set Item_subselect::changed in the Item_subselect::fix_fields()
if an error occured during subquery transformation.
That prevents us of further processing incorrect subqueries after
Item_in_subselect::select_in_like_transformer().

Various parts of code used different 'precision' arguments for sprintf("%g") when converting
floating point numbers to a string. This led to differences in results in some cases
depending on whether the text-based or prepared statements protocol is used for a query.
Fixed by changing arguments to sprintf("%g") to always be 15 (DBL_DIG) so that results are
consistent regardless of the protocol.
This patch will be null-merged to 6.0 as the problem does not exists there (fixed by the
patch for WL#2934).

fails after the first time
Two separate problems :
1. When flattening joins the linked list used for name resolution
(next_name_resolution_table) was not updated.
Fixed by updating the pointers when extending the table list
2. The items created by expanding a * (star) as a column reference
were marked as fixed, but no cached table was assigned to them
(unlike what Item_field::fix_fields does).
Fixed by assigning a cached table (so the re-preparation is done
faster).
Note that the fix for #2 hides the fix for #1 in most cases
(except when a table reference cannot be cached).

The problem is that field names constructed due to wild-card
expansion done inside a stored procedure could point to freed
memory if the expansion was performed after the first call to
the stored procedure.
The problem was solved by patch for Bug#38691. The solution
was to allocate the database, table and field names in the
in the statement memory instead of table memory.

A stored procedure involving substrings could crash the server on certain
platforms because of invalid memory reads.
During storing the new blob-field value, the cached value's address range
overlapped that of the new field value. This caused problems when the
cached value storage was reallocated to provide access for a new
characater set representation. The patch checks the address ranges, and if
they overlap, the new field value is copied to a new storage before it is
converted to the new character set.

Send_field.org_col_name has broken value on secondary execution.
It happens when result field is created from the field which belongs to view
due to forgotten assignment of some Send_field attributes.
