George Bosilca 7dfdf3e907 A lot of MX fixes.
1. Allow MX bonding via btl_mx_bonding MCA parameter. With this on, Open MPI
  suppose that lib MX will do the bonding, and we will only return one BTL.
  Otherwise, we return as many as devices.
2. Decrease the memory footprint, by cleaning up what we store about the
  peers and how we store it.
3. Allow multiple MX routes that share the same mapper. In this particular
  case we will link by their nic_id.
4. Allow multiple MX routes with multiple mappers. In this case we match
  the NICs based on the last 6 digits of the mapper MAC.
5. Increase the size of the eager and rendez-vous eager limits in the
  case where we are unable to register an unexpected callback with MX.
6. Increase the default max number of MX fragments.
7. Increase the max number of MX BTLs.
8. Only allow mx_if_include and mx_if_exclude if we have acess to the
  mapper.
