c398c65bee Revise the SQLITE_OPEN_NOFOLLOW so that it actually uses O_NOFOLLOW in the 
open() system call.  This backs out the SQLITE_ACCESS_SYMLINK value but adds
the new SQLITE_OK_SYMLINK return code from the xFullPathname method of 
sqlite3_vfs when that routine resolves symbolic links. O_NOFOLLOW is always
included in open() system calls for journal files.

eafb9a0ae5 Make the winTruncate() method of the windows VFS be a no-op if there are 
outstanding references to the memory-mapped pages.  Otherwise, memory might
be deleted out from under those references when the file is remapped during
the truncate operation.
