There was a mismatch between the structure for mca_rcache_vma_t and
the OBJ_CLASS_INSTANCE. One was opal_list_item_t and the other was
ompi_free_list_item_t. The super class in the structure looks like it
is the correct one. Changed the superclass in OBJ_CLASS_INSTANCE to
match.
If there are not enough resources (e.g., low VFs), we can end up
calling finalize_one_channel() on the same channel multiple times. So
ensure to NULL out fields that we have freed already so that we do not
try to free them a second time.
Fixes CSCus26648.
Fix the ordering so that we obtain the usnic netmask information
*before* we do the filtering based on CIDR-specified networks.
Also requires upstream Github libfabric commit 3976745.

Turns out the alps plm component wasn't changing the state
of the job upon terminating the orted's in the case of
an abnormal termination. This caused mpirun to hang
with a zommbie'd aprun process if an orted on a node
in the job was killed via signal.
We had several problems in the old code:
1. We were specifying an arbitrary timeout (100 ms) and then abandoning
all remaining pending AV insert operations. We would then free the
endpoint buffer that we gave to fi_av_insert(), usually causing
libfabric's progress thread to write to a freed buffer.
2. We were claiming in a show_help message that the timeout was
controllable via an MCA parameter. This commit removes that
parameter, since there's no good method for us to specify a timeout
like this to libfabric right now.
3. We also weren't waiting for the correct number of fi_av_insert()
operations to complete. We were waiting for nprocs, which is
accidentally fine for 2 procs on separate hosts, but not for most
other proc counts.

In the course of doing some testing with how orted's
handle signaled child processes, found out that very
often doing a kill -9 on a process on a node just
results in the job hanging. The problem was that the
orted odls/errmgr was not properly handling the exit_code
being returned from waitpid. Now mark the proc state
as ORTE_PROC_STATE_ABORTED_BY_SIG if the exit_code
from waitpid indicates the process exited owing to
a signal.
For systems with OFED's lacking XRC support, commit b3617e73
broke the build of the openib btl. This commit addresses
the issues introduced by this commit.
This is the master version of @ggouaillardet's patch from
open-mpi/ompi-release#148 (there was a minor conflict to fix and
several fuzzings of line numbers).
