Signcheck doesn't work

[karol-gro]

It seems that -signcheck option, while mentioned in help messages, doesn't work.

Steps to reproduce:

1. download Windows 64-bit binary
2. run meshagent64-Other.exe -signcheck

Expected result:

some message about check failing or passing

Actual result

help message as if command was invalid.

Here's detailed output:

     --agentName="alternate name"            Specify an alternate name to be provided by the agent.

Notes:

I noticed that in

MeshAgent/meshservice/ServiceMain.c

Line 593 in 542d57b

if (argc > 1 && strcmp(argv[1], "-export") == 0 && integragedJavaScriptLen == 0)

all the options like -nodeid are handled, but there is no-signcheck. I found also that there is function signcheck_verifysign in header file and its implementation, but it seems to be never called. But I'm no C developer, but it seems like it's only a matter of handling this option
