the base send and receive request from the pml_base, we can solve our problem
if we construct the convertor attached to any request in the pml_base_construct
function. At the end of the life time for each request (here life time is
related to one utilisation, without taking in account the cache) we release
all information attached to the convertors in the _FINI macro by calling the
ompi_convertor_cleanup.

to be supported by mellanox vapi.. perhaps this will be supported in the near
future, for now it doesn't hurt to have it in the trunk
Also cleanup the receive descriptor posting macro's..

at the top-level MPI API function. This allows two kinds of
scenarios:
1. MPI_Ireduce(..., op, ...);
MPI_Op_free(op);
MPI_Wait(...);
For the non-blocking collectives that we're someday planning -- to
make them analogous to non-blocking point-to-point stuff.
2. Thread 1:
MPI_Reduce(..., op, ...);
Thread 2:
MPI_Op_free(op);
Granted, for #2 to occur would tread a fine line between a correct and
erroneous MPI program, but it is possible (as long as the Op_free was
*after* MPI_reduce() had started to execute). It's more realistic
with case #1, where the Op_free() could be executed in the same thread
or a different thread.

stage fairly confident that
- it works in most scenarious (with symmetric hierarchies, with asymmetric
hierarchies, wihout hierarchies - it just removes itself)
- it does not create too many problems (I am not aware of any at least)
- it does not slow down startup anymore dramatically (thanks to the fixes of
Brian, Jeff, Tim and a significant reduction in the number of collective
operations in the comm_query)
Any feedback is highly welcome.

quering some of the collective components. Up to now, it just worked
somehow, but now with correct reference counting for ops in place, it
refused :-)

started to add static (fixed if) statement based decision rules based on gigE numbers
added mca params so that a user can force a certain algorithm/segment/topo on a per collective basis
(this is not in the fixed call path but only in the dynamic (at com create) call path).
(these params can be used by test suites such as OCC to choice which algorithm they are using).

This takes care of Troy's first segfault problem, and compile errors that will likely happen as soon as Ken applies George's patch and runs make again.

Note, we are failing the ring tests in the intel p2p test suite, but we seem
to fail the same tests under the current trunk.. will look into this further.
