start implementation of UPnP-gw-DeviceProtection-V1

[cclecle]

This patch will allow connection to SSL device with self-signed certificate, as explained in UPnP-gw-DeviceProtection-V1-Service specifications.

Its working but will raise a few warning from sublibrary (because of self-signed warning).

Next step:

• SSDP parser will be updated to fetch 'SECURELOCATION.UPNP.ORG' field and SOAP to use it if available
