iotivity: update to version 1.2.1

This does the following changes:
* update to version 1.2.1
* add iotivity-resource-directory-lib, this is needed by most
  applications now
* do not activate security support by default, this caused some
  problems and needs some more settings to setup.
* use sqlite version from normal package feed instead of using an own
  version
* build against LEDE version of mbedtls
* update example security configuration
* remove some patches that went upstream
* add some new patches fixing problems observed in my environment, most
  of them are on their way upstream.
