drh ef86b942b9 Code changes that make it easier to prove that no 32-bit integer overflows 
happen during memory allocation.  No problems fixed; this change is just
to make future maintenance easier.

drh c850c2be75 Add two new sqlite3_db_config() options that enable the ATTACH command 
to create new database files and to open databases read/write.  Both
default to on for backwards compatibility.

drh 1521ca4c20 Refactor the SrcItem object so that information about subqueries is stored 
in a separately allocated Subquery object.  This reduces the memory requirements
for SrcItem and makes the code run faster.  It also provides an expansion path
for subquery processing that does not burden simple queries.  The current
checking mostly works, but there are still issues that need to be tracked
down and fixed.
