[CWEB] Finally make use of type 'mode' -- C-style.

'typedef int mode' was never actually used in CWEB 2.7 and up (and, most
likely, down).  However, 'boolean' and the two @definitions isn't quite
correct either.  See line 3907 of WEAVE.WEB for the original intent.

The new 'typedef enum' restores the classic code in C-style.
