EAL threads

[Mattias Rönnblom]

I have some lcore-related questions:

The documentation make use of the term "non-EAL thread". Is a non-EAL 
thread the same thing as a non-lcore thread? I.e., are there EAL threads 
that are not lcore threads?

I also have a question related to rte_register_thread(): shouldn't the 
documentation say the user is assumed to pin the calling thread to some 
core? That is the expectation, correct?
