There was an argument that was barely used, and on return at the PML
level it contained nothing usable. It has been removed, so now we're
using less memory ...

(related to the presence of posix threads and ptmalloc2) is now a
little outdated: since we don't build ptmalloc2 as part of libopal
anymore, the openib BTL's requirements are not directly tied to
ptmalloc2's anymore. Specifically, I altered the test to:
1. At compile time, if no threads are found, the ptmalloc2 component
is going to be built, '''and the ptmalloc2 component is going to be
inside libopal,''' then refuse to build the openib BTL.
1. At run time, if no threads were available at compile time and the
ptmalloc2 component is part of the process, then refuse to use the
openib BTL.

This commit was SVN r19642.
Rationale:
1. This value has already changed since v1.2 (v1.2 MPI_MAX_PORT_NAME
== 36). Hence, this commit simply increases the value from a
previous change.
1. The changes does increase OMPI's memory footprint slightly, but
only when using MPI-2 dynamics. So it is expected that the change
will have minimal impact on the overall footprint.
1. The change is helpful for nodes that have 4 or more IP networks
(e.g., regular ethernet and multiple IP-over-<pick your favorite
high-speed network> networks). Without this change, invoking
MPI_COMM_SPAWN on hosts with 4 or more IP networks will fail
because we'll exceed 256 bytes for the port name. Some OMPI
developer test clusters already have this kind of configuration
(e.g., Cisco); it is expected that this is not too common in the
real world yet, but with "manycore" coming, having multiple
IP-based networks in a single server will likely become more
common.

help messages so that users only see the message once instead of N
times when their MPI app crashes.
Note that there is a tradeoff here -- we now call malloc in this
particular "show the error" code path. This shouldn't usually be a
problem, because the errors typically displayed through this mechanism
are MPI API argument problems (e.g., sending a negative count to
MPI_SEND), and not memory errors. But such API argument errors could
be a consequence of of a prior memory error, so there's a nonzero
chance that the error failure will fail to print because malloc
failed. In this case, the user can disable help message aggregation
(via the orte_base_want_aggregate MCA parameter) and we'll fall back
to the no-malloc code path (but without aggregation).
Note that we won't aggregate before MPI_INIT or after MPI_FINALIZE.
So if you call an MPI function before MPI_INIT / after MPI_FINALIZE,
you'll still see the error message N times. Nothing we can do about
that; we need ORTE to do the aggregation properly (which is obviously
unavailable before MPI_INIT / after MPI_FINALIZE).
