coll/basic: fix segmentation fault in neighborhood collectives if the degree
of the topology is higher than the communicator size

It is possible to have a topology degree higher than the size of the communicator.
For example, a periodic cartesian communicator on MPI_COMM_SELF. This will leave
the neighborhood collectives with a request buffer that is too small.

This commits introduces a semantic change :
from now, c_topo must be set before invoking coll_select
* comment on communicator creation in mca_topo_base_dist_graph_create(...)
* use accesors to retrieve topo info
Add missing Fortran binding for Win_allocate.
btl/vader: fix typos in the help file
btl/vader: more updates to the help messages
Add the ability for a tool that requests spawn of a job to also request forwarding of all output to the tool. The tool is responsible for its own call to push its stdin to the new job. The push request can come -after- the job is started, but the pull request has to be done during the spawn procedure or else output can be lost.
Ensure that the proxy "pull" of output gets directed to the requesting tool, which is no longer just the sender since the HNP may be making the request on behalf of someone else
