improve configury to check whether icc is handling no long double.
This prevents seeing 100s of messages like this:
icc: command line warning #10148: option '-Wno-long-double' not supported
A similar patch will be needed for pmix.

The btl/ofi does not currently utilize the common ofi include/exclude
list. Added verification code similar to the mtl/ofi that will check if
the info object is in the include or exclude list. If it isn't in the
include list or is in the exclude list, validate_info will return
OPAL_ERROR. The btl/ofi will no longer pass a provider name as a hint
when calling getinfo, instead filtering the provider during
validate_info.
This patch also moves the is_in_list MTL function into common code and
adds additional debugging output to the BTL to match the MTL standard.

The default algorithm selections were out of date and not performing
well. After gathering data from OMPI developers, new default algorithm
decisions were selected for:
allgather
allgatherv
allreduce
alltoall
alltoallv
barrier
bcast
gather
reduce
reduce_scatter_block
reduce_scatter
scatter
These results were gathered using the ompi-collectives-tuning package
and then averaged amongst the results gathered from multiple OMPI
developers on their clusters.

If building Open MPI with sanitizers, e.g
$ configure CC=clang CFLAGS=-fsanitize=address ....
configure test programs are also build with the sanitizers and will
report errors resulting in configure to fail.

There are 2 reasons for this:
- pending CUDA events are not progressed by this BTL, so anything that becomes
asychronous will never be completed.
- we use the packed data on the shared memory backing file, and this will be
returned to the peer process upon return (thus if we copy asynchronously we
might not copy the right data).
