[Olsr-dev] rfc5444_reader documentation

I took your example code, cleaned it up a little bit and added it to
the repository in the example section. Hope you will find it easy to
The main issue with your code was that your reader part declared a
"message TVL type 2" as mandatory for your callback, but your writer
added the "message TLV type 0" and "message TLV type 1". Because of
this the callback was never called.
The reader guarantees that the 'mandatory" TLVs are present when the
block_callback() function pointer is called. Otherwise it will call
the block_callback_failed_constraints() function pointer.
