opal_check_portals.m4: remove this unused file

It looks like OPAL_CHECK_PORTALS is not used anywhere; it looks like
it has been completely replaced by opal_check_portals4.m4
(OPAL_CHECK_PORTALS4).

opal_check_portals.m4: remove this unused file
add initial support for an alps odls component

It turns out that the support for Open MPI apps on
Cray was hanging on a thin thread of support when
using the mpirun job launcher.  It just happened that
with a certain set of configuration options things would
work.  This is bound to backfire at some point.

To fix this weakness, as well as to allow for mpirun launched
jobs to benefit from many of the advanced placement features
provided by the Cray Linux Environment (as opposed to the hwloc
only default env of orte), a new odls alps component is introduced.

fix compare_nodes bug in alps ras component

There was an obvious bug in the alps/ras component compare_nodes method
which resulted in the function always evaluating the nodes
as being equivalent.
fix some compiler warnings in ras/alps
Add *.dwarf to the ignores as Mac Yosemite now generates these files
Add a marker for the max attr value being used by ORTE so that other, higher-levels can also use the attribute system
All other layers to register their own print-attribute functions so we can maintain pretty-print capabilities as the attributes are extended.
Add the LSF libraries as required for static build
Update the interface to provide a cleaner interface for RDMA operations.

The old BTL interface provided support for RDMA through the use of
the btl_prepare_src and btl_prepare_dst functions. These functions were
expected to prepare as much of the user buffer as possible for the RDMA
operation and return a descriptor. The descriptor contained segment
information on the prepared region. The btl user could then pass the
RDMA segment information to a remote peer. Once the peer received that
information it then packed it into a similar descriptor on the other
side that could then be passed into a single btl_put or btl_get
operation.

Changes:

 - Removed the btl_prepare_dst function. This reflects the fact that
   RDMA operations no longer depend on "prepared" descriptors.

 - Removed the btl_seg_size member. There is no need to btl's to
   subclass the mca_btl_base_segment_t class anymore.

pml/ob1: when using btl_get try to register the entire region before
attempting to break the get into multiple rdma fragments

A little background. Historically ob1 always registered the entire memory
region when the RGET protocol was in use. This changed when Mellanox
added support to fragment RGET using the btl_prepare_dst function. Now
that the BTL layer has changed to split out the limits of get/put there
is explicit fragmentation code in ob1. Before this commit the registration
was still done per RGET fragment.

This commit will attempt to register the entire region before creating
RGET fragments. If the registration is successfull then all RGET
fragments will use this registration otherwise they will each attempt
to register their own segment of the receive buffer. If that fails
enough times each fragment will give up and fall back on send/recv.
btl: remove des_remote/des_remote_count from the mca_btl_base_descriptor_t
structure

This structure member was originally used to specify the remote segment
for an RDMA operation. Since the new btl interface no longer uses
desriptors for RDMA this member no longer has a purpose. In addition
to removing these members the local segment information has been
renamed to des_segments/des_segment_count.
pml: updates to reflect member changes in mca_btl_base_descriptor_t
and mca_btl_base_module_t structures
Update the scif and openib btls for the new btl interface

Other changes:
 - Remove the registration argument from prepare_src since it no
   longer is meant for RDMA buffers.

 - Additional cleanup and bugfixes.
