[SR-Dev] library naming

Hello,

I couldn't get the message with a final decision regarding the library naming scheme. Andrei used libsr_xyz at some point, I also like this one. Henning committed directly lib/trie in his branch.

I will look soon to make the library out of mi, thinking of: libsr_kmi or libsr_mi, depending or not whether we want to mark the origin.

So, two things to decide: - do we stick to libsr_ as prefix to all new libraries included in srouter? - do we want to mark the origin of the library? Short term, might be good as pattern to know what is required for k version of the module. This can be fixed with good documentation. Long term the name might look strange.

Cheers, Daniel
