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.

Change os_unix.c to propagate ENOENT errors back to sqlite as SQLITE_IOERR_DELETE_NOENT. Have SQLite ignore these where they are benign and propagate them back to the caller where they may indicate a file-system malfunction of some description.

Disable the table selection rule that tried to prevent full table scans from
...
migrating to the outer loop unless they were optimal. The new scaling of
outer-loop costs by cost of inner loops obviates the need for that step. And,
in fact, that step causes problems with the new inner-loop cost accounting.
