263a8b660f Avoid an out-of-bounds read on a recovery attempt using a carefully crafted 
database and rollback journal with mismatched page sizes.  The test case for
this is in TH3.

d33bcb8a3c Improvements to PRAGMA integrity_check for better detection of malformed 
records.  Integrity_check now avoids returning SQLITE_CORRUPT on a corrupt
record.  Also includes microoptimizations that I stumbled over while working
on integrity_check.
