Use ValueError instead of SyntaxError throughout.

SyntaxError has a much more specific meaning, and some software, such as
`ipython', expect it to carry lots of other detailed information.

So abolish the `SYNERR' macro, and use `VALERR' instead consistently.  I
wish I had an excuse for this blunder, but I don't.
