- We hide the rules, is there a reason to keep struct
rte_lpm_rule_info and struct rte_lpm_rule exposed?

- Rather than have translations lpm -> i_lpm, in many places of this
library, we should translate only in the functions exposed to the
user.
Besides, it is a bit hard to read between internal_lpm and i_lpm, I
would adopt a single i_lpm convention for the whole file.
I went and tried to do it (big search and replace + build tests, no
runtime check though).
This results in:
https://github.com/david-marchand/dpdk/commit/4e61f0ce7cf2ac472565d3c6aa5bb78ffb8f70c9

What do you think?
