faa59554c3 Add support for CREATE TABLE IF NOT EXISTS. (CVS 2847)

d946db0064 Add serial-types 8 and 9 for integer constants of 0 and 1 that use zero 
bytes of storage.  Make the default file format 4.  Add the
SQLITE_DEFAULT_FILE_FORMAT compile-time option to lower the default
file format number so that newly created databases can be read and
written by older versions of SQLite. (CVS 2845)
