moxi/win32: Reduce usage of low TCP/IP listen ports for internal moxi pipes.

A customer has noted that moxi listens on a number of low numbered ports in addition to the configured listen port(s) - default 11211. These are causing problems for the customer as they can sometimes block their other applications which expect to be able to listen on these ports.

The customer would like to be able to configure the ports used here, essentially to 'blacklist' certain ports from being used by moxi, or if possible remove these additional listening ports altogether.

Example of the ports used (windows netstat; note this only occurs on Win32, OS X / Linux netstat is clean):

$ less netstat_win.txt |grep -A1 LISTENING|grep -B1 moxi|grep -v "--"
TCP 0.0.0.0:1121 0.0.0.0:0 LISTENING
[moxi.exe]
TCP 0.0.0.0:11211 0.0.0.0:0 LISTENING
[moxi.exe]
TCP 127.0.0.1:1051 0.0.0.0:0 LISTENING
[moxi.exe]
TCP 127.0.0.1:1053 0.0.0.0:0 LISTENING
[moxi.exe]
TCP 127.0.0.1:1096 0.0.0.0:0 LISTENING
[moxi.exe]
TCP 127.0.0.1:1103 0.0.0.0:0 LISTENING
[moxi.exe]
TCP 127.0.0.1:1110 0.0.0.0:0 LISTENING
[moxi.exe]
TCP 127.0.0.1:1117 0.0.0.0:0 LISTENING

TCP [::]:1120 [::]:0 LISTENING
[moxi.exe]
TCP [::]:11211 [::]:0 LISTENING
