These patches are making it possible to provide the compiler settings
from the environment so LEDE can change them. This replaces the old
patches with the versions send for upstream inclusion.

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.

IoTivity is a Internet of Things framework implementing the Open
Interconnect Consortium Specification.

The current version of IoTivity is still in heavy development and does
not support all its intended features, but I still want to add it to
the packages feed to make it easier for others to extend the OpenWrt
support.
