coll: code cleanup
...
- instead of coll_base_comm_get_reqs(2) for irecv/isend, use only
one request allocated in the stack and do a irecv/send
- instead of ompi_request_wait_all(2), simpy ompi_request_wait

Cleanup the memory handling for temporary buffers in
...
some of the collective modules. Added a new function
opan_datatype_span, to compute the memory span of
count number of datatype, excluding the gaps in the
beginning and at the end. If a memory allocation is
made using the returned value, the gap (also returned)
should be removed from the allocated pointer.

Never allocate a temporary array for the requests. Instead rely on the
...
module_data to hold one with the largest necessary size. This array is
only allocated when needed, and it is released upon communicator
destruction.

Split the tuned framework in two. Move all the functions down in the
...
base, so that they can now be used by all modules. Keep the decision
functions in tuned.
