56d88aad29 Harden the xShmLock method of both the unix and Windows VFSes so that they 
are robust against being invoked when the SHM file is not open.

f8c4c3a09f The windows VFS accepts query parameter "exclusive=true" to cause it to 
take a mandatory file lock, preventing other applications from even
reading the file.

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.
