drh 0d0614bdc6 Memory-mapped I/O is now on by default. The "PRAGMA mmap_limit(N)" can be 
used to issue a hint to the VFS to limit mmap space to N bytes.  The VFS
is free to ignore that hint if desired.  However, if "PRAGMA mmap_limit(0)"
is used, xFetch is never called.

drh 3f4d1d1b02 Attempt to use a covering index even on a full table scan, under the theory 
that the index will be smaller and require less disk I/O and thus be faster.

drh 0f198a7409 Change the ROLLBACK command so that pending statements to not block it. The 
pending statements instead return SQLITE_ABORT upon next access.  Note: This
causes separate shared-cache connections in read_uncommitted mode to abort as
well.

dan 1316700e54 Add a test to check that the incrblob API cannot be used to write to an IPK column. Also a comment to explain why the incrblob code does not need to check if a column is part of a parent key before writing to it.
