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)

93c829c110 Add corruptD.test, a container for testing the "cell overflow" problem. Also shuffle a small amount of code in BtreeInitPage() to check that the page header pointer to the start of the cell offset array is set to a sane value. (CVS 6710)
