9b4e7898d7 Add a test case to the fix to PRAGMA integrity_check in the previous check-in.

78bc1339ac Do not accept a string that looks like a number used as an argument to 
PRAGMA integrity_check as a number.  Treat it as a table name that just
happens to look like a number.

2ae4531c89 Omit the OP_SqlExec to "PRAGMA integrity_check" added by [348fa7aaf7958b3f] 
because it is a no-op.  Even if the integrity_check failes, the CREATE TABLE
is stull successful.  The OP_SqlExec just burns CPU cycles for no reason.

b11daa50f9 Fix issues in [/info/1e227ad9f413227f|LIMIT/OFFSET support for virtual tables]. 
The first problem was reported by
[forum:/forumpost/c243b8f856|forum post c243b8f856].  That report prompted
an enhancement to the generate_series() (also included in this merge) which
in turn identified other similar issues.

ec14ef80b0 Improvement to the way that affinity is determined for columns of a

to accommodate the data types coming out of the other arms.

23afc2c4ec Back out the previous change on this branch. In its place: Determine the 
affinity of a subquery by the left-most arm of the subquery that has an
affinity other than NONE.  In other words, scan from left to right looking
for an arm of the compound subquery with an affinity of BLOB, TEXT, INTEGER,
or REAL and pick the first one found.  Or stay with NONE if no arm has a
defined affinity.  Test cases added.

2469350ad9 For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db.
