VIQR<->VISCII conversion and VISCII ctype-like routines

This port offers VIQR<->VISCII (RFC 1456) conversion and VISCII ctype-like routines for Vietnamese text processing. Of prime interest is the finite state machine that reads 7-bit Viet-Net style Vietnamese and produces 8-bit output. Developers are encouraged to take advantage of these routines for these reasons: - Parsing task is greatly simplified - Makes one's code easier to port from one character encoding to another - Ensures a consistent user interface across many software packages
