This commit removes deprecated APIs and replaces them with routines that provide similar functionality without the flexibility originally offered by the deprecated APIs. Removing deprecated routines will help us to be prepared once the new IP stack is ready (ZEP-793). Furthermore, this commit will also help us to move our current DNS Client implementation to the lib/iot directory, as specified by ZEP-847. This commit removes the netz library from the DNS client sample application. UDP functionality is replaced by primitive routines. Specifically, the following changes are applied by this patch: - Remove netz routines - Remove app_buf data structure - Introduce primitive data types in the DNS client code - Introduce primitive network routines - Add a header file containing configurable parameters Jira: ZEP-793 Jira: ZEP-847 Change-Id: I0302133da77308f0cdd9ace2c0265e6b77673ff0 Signed-off-by: Flavio Santes <flavio.santes@intel.com>
