d300171150 Move the sqlite3MinimumFileFormat() routine from build.c over to alter.c 
since alter.c is the only code that uses it.  Additional changes and
cleanup to build.c to facility coverage testing. (CVS 6630)

c4a64facce Rework the logic that generates a schema for tables created using 
"CREATE TABLE ... AS SELECT ...".  Instead of trying to copy the raw
datatype string from the right-hand side, just make the type one 
of TEXT, INT, REAL, NUM, or nothing.  This is much simpler than 
trying to parse and quote datatype strings.  Other minor 
implifications to build.c are bundled with this change. (CVS 6626)
