9fc5b4a539 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.

98d312fc3e Improvements to the command-line argument parsing in the 
command-line shell.  Command-line options can now occur either before
or after the database name and first command and are still accepted and
processed.  Command-line options are processed even if no database name
is given (and :memory: is assumed).

b483eba051 Ensure that when the source of a backup is a database that is zero bytes in size, the final destination database consists of at least one page. Truncating it to zero bytes is equivalent to zeroing the schema cookie and change counter, which can cause problems for existing clients.

a9e3fc05f5 Fix some corner case behavior in the new ORDER BY optimization logic. 
Remove the SQLITE_OrderByIdx bit from the 
SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many
TH3 tests to fail when the NO_OPT configuration parameter was engaged,
and since there really isn't any need to turn that optimization off.
The SQLITE_OrderByIdxJoin bit remains.
