// The ParseHostPort function parses a VNC host name which can be specified
22
// in one of these formats:
23
//   (1) hostname
24
//   (2) hostname:display   (display < 100)
25
//   (3) hostname:port      (port >= 100)
26
//   (4) hostname::port
27
// The function determines and returns the port number, and modifies str[]
28
// by inserting a zero byte in place of the first colon found in the string.
29
// The algorithm of determining the port number is as follows:
30
//   (1) if there are no colons in the string, base_port is used;
31
//   (2) if there is one colon and the following number is less than 100,
32
//       then the port number is calculated by adding this number (display
33
//       number) to base_port;
34
//   (3) if there is one colon and the following number is 100 or greater,
35
//       then this number is interpreted as a port number;
36
//   (4) if there are two colons, the following number is always treated as
37
//       a port number.
