- utilizing coll_tuned_util functions
- setting line length to 80.
This implementation uses standard send messages (instead of synchronous ones).
The change improved our performance over MX multiple number of times, however,
there exists a small potential that last message to be sent can be delayed
(until next mpi call, which means potentially infinitely).
If this shows to be a problem, I will modify the algorithms to use synchronous
send as last operation (which will incur performance penalty again).

- in allgather algorithms I replaces irecv-isend-waitall sequence with
call to ompi_coll_tuned_sendrecv
- most of the functions in util code and allgather decision function conform to 80 character line width.

that a) STATUS[ES]_IGNORE *is* NULL, and b) ROMIO blindly sends its
status through to STATUS_SET_ELEMENTS, even if the status is IGNORE.
So we have some legal cases where IGNORE can be passed through here.
Well, that's what we get for trying to do good error checking. :-(

- Fix some fpritnf's in ompi_mpi_abort() that incorrectly assumed that
we were always being invoked from MPI_ABORT (ompi_mpi_abort() may be
invoked from a bunch of different places)
- Also try to opal_backtrace_print() if opal_bactrace_buffer() is not
supported.
- Print a message in MPI_ABORT if we're aborting.

This is somewhat limited currently for expample, if you have 3 ports on Node A and 5 ports
on Node B then the peers will use 3 ports to communicate with each other.
This is on a subnet basis, so for any pair of nodes we take the
intersection of the available ports within a subnet.
We use subnets to determine reachability for lazy connection establishment. So
if Node A and Node B each have two HCA's (on seperate networks) then the
subnet's must be distinct, otherwise we will try to wire up HCA's on seperate
networks.

* Make sure that the pval always writes to the correct portion of the
lval. This only matters on 32 bit big endian machines.
* On 32 bit machines when assigning to pval, the other 4 bytes of lval
weren't being written, which could lead to bogus data
We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes. Refs trac:587

the value of __n holds. This is not a problem in the first case
because sizeof(int) == sizeof(MPI_Flogical), so no alloc is actually
performed (which is most compilers, and why we haven't been bitten by
this yet). But the second case -- where sizeof(int) !=
sizeof(MPI_Flogical) -- is definitely a problem and needs the "+1" in
the alloc, or Bad Things will happen.
