C Device SDK (public preview)

• Added support on Azure IoT C SDK for public-preview of Device Streaming.

vcpkg:
The Azure IoT C SDK vcpkg can be accessed through https://github.com/Microsoft/vcpkg.
Please follow the initial instructions for deploying the azure-iot-sdk-c vcpkg. To access the public-preview features please use the following syntax instead:

vcpkg install azure-iot-sdk-c[public-preview] 

and, if you wish to export the nuget packages,

vcpkg export azure-iot-sdk-c[public-preview] --nuget

apt-get:
Installing the apt packages for Azure IoT C SDK public preview can be achieved following these instructions, with the difference that the preview ppa address should be used:

sudo add-apt-repository ppa:aziotsdklinux/azureiot-preview
