// The ParseHostPort function parses a VNC host name which can be specified
// in one of these formats:
// (1) hostname
// (2) hostname:display (display < 100)
// (3) hostname:port (port >= 100)
// (4) hostname::port
// The function determines and returns the port number, and modifies str[]
// by inserting a zero byte in place of the first colon found in the string.
// The algorithm of determining the port number is as follows:
// (1) if there are no colons in the string, base_port is used;
// (2) if there is one colon and the following number is less than 100,
// then the port number is calculated by adding this number (display
// number) to base_port;
// (3) if there is one colon and the following number is 100 or greater,
// then this number is interpreted as a port number;
// (4) if there are two colons, the following number is always treated as
// a port number.
