[issue41662] Bugs in binding parameters in sqlite3

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

There are few bugs in the code for binding parameters specified in the sqlite3 
module:

1. If argument "parameters" is a list, PyList_GET_ITEM() is called in a loop, 
but the size of the list is read only once before loop. Since the list can be 
changed during iteration, it can cause reading past the end of the list.

2. If argument "parameters" is a custom sequence, all exceptions raised in 
__len__() (including KeybordInterrupt) are overridden by a ProgrammingError.
