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
