1d8b85bed1 Have the crash-test infrastructure code in test6.c read and write the 512-byte block containing the pending-byte lock as normal. Earlier versions did not access this part of the file in order to avoid triggering an assert in os_unix.c. But the assert() has since been removed. And not reading/writing this part of the file causes problems for multiplexor tests.

09fe614372 Add a new sqlite3_test_control() that indicates that database files are 
always well-formed.  Use this during testing to enable assert() statements
that prove conditions that are always true for well-formed databases.

de1a8b8c69 Change the REAL-to-INTEGER casting behavior so that if the REAL value 
is greater than 9223372036854775807.0 then it is cast to the latest
possible integer, 9223372036854775807.  This is sensible and the way
most platforms work in hardware.  The former behavior was that oversize
REALs would be cast to the smallest possible integer, -9223372036854775808,
which is the way Intel hardware works.
