bosilca 872cf44c28 Improve the opal_pointer_array & more (#3369)
* Complete rewrite of opal_pointer_array
Instead of a cache oblivious linear search use a bits array
to speed up the management of the free space. As a result we
slightly increase the memory used by the structure, but we get a
significant boost in performance.

* Do not register datatypes in the f2c translation table.
The registration is now done up into the Fortran layer, by
forcing a call to MPI_Type_c2f.
