Use preprocessor macros to automatically detect whether or not posix_allocate() is available. (It is generally available on Linux but not on Mac.) Ticket [5eaa61ea1881040b17449ca043b6f8fd9ca55dc3] Closed-Leaf check-in: 597333f1 user: drh tags: tkt-5eaa61ea18

When available, use posix_fallocate() rather than ftruncate() to allocate space for mmap()ed -shm files, since posix_fallocate() gives an error if no disk space is available whereas ftruncate() is silent and leaves the system vulnerable to a SIGBUS upon first write to the mmap()ed region.
