3b2a3fa42e Enable cell overflow checking in sqlite3BtreeInitPage() using the 
compile-time option SQLITE_ENABLE_OVERSIZE_CELL_CHECK.  Change the tests
so that they recognize different error messages depending on the setting
of this macro. (CVS 6735)

corrupt7.test result vectors for a couple of cases where the error report

69e931e7bb Change the pcache1.c implementation so that the "header" occurs at the end 
of page buffer, not at the beginning.  This insures that the 20 bytes
immediately following the page buffer are mapped if a read of the page
buffer overruns due to a malformed cell. (CVS 6711)
