0e9365ced3 Log all error from close() in os_unix.c to sqlite3_log() but do not attempt to 
report errors back up to the application.  Update the unix error logging to
put the most important information earlier in the message.

37e8b5b2cc Fix the computation of the offset on the mmap() for the Nth shared memory 
region.  Because of the way shared memory is accessed, the old computation,
though wrong, still happened to always get the right answer.  Nevertheless,
it is good to do the computation correctly.
