STM32 / Crossbar.io HTTP Bridge example

[oberstet]

A plain C code example using the STM32 SDK: a HTTP(S) client that issues HTTP requests to the HTTP Bridge of Crossbar.io to publish WAMP events and call WAMP procedures.

Hence, this example does not use AutobahnC (for full WAMP), but only uses plain HTTP(S) 1.1 requests.

The example should live under: /device/stm32/components/http_bridge_client.

This example is the STM32 flavor of https://github.com/crossbario/iotcookbook/issues/1.
