efd95a7aca Do not raise an SQLITE_CORRUPT error in Recoverymode 
if the database size in the header is larger than the physical file
size.  This facilitates recovery of a database in which the database size
field has been corrupted.

f8888bb22a Allow SQL statements to be executed from within a progress callback. 
Be warned, however, that the progress callback might be called
recursively in this case.  It is up to the program to disable the
progress callback to prevent recursive invocations.
