Add "mg_get_local_addr". Return the local listening address used.

[mdw-at-linuxbox]

civetweb can listen to multiple addresses. Some of these can have
ssl enabled, and some not. The "using_ssl" flag is
already returned to the client, but the local address (lsa) is not,
This allows a calling application to determine on which local
address/portno a connection was accepted.

Will this go into civetweb upstream?

[mdw-at-linuxbox]

I structured most of the work I did to civetweb with an eye towards making it palatable upstream. But I haven't talked to upstream so don't know how hard it actually would be to get any of our civetweb changes upstream.

@mdw-at-linuxbox Would you plz merge this first and update civetweb submodule? or remove invokation of
mg_get_local_addr ? This broken master(d644f911e6acfd75f79a44cd73e6b3b9c042ad15) build:

@mdw-at-linuxbox it looks like we're still maintaining this in our fork - has this been proposed upstream?
