Fix the allocation for the pointers to the btl structures.

We were only allocating one whereas we would typically need
one per interface.  Most of the time we got lucky and we 
happily trundled over unallocated memory.  But with enough
interfaces, we would get a SEGV.

Also add include to fix compilation with static libs.
