Introduce 'osmo_tlv_prot' abstraction for validation of TLV protocols
This extends our existing TLV parser with the ability to
* validate that mandatory IEs of a given message are present
* validate that all present IEs are of required minimum length
Introducing this generic layer will help us to reduce open-coded
imperative verification across virtually all the protocols we
implement, as well as add validation to those protocols where we
don't properly perform related input validation yet.
