Jeff Squyres 9db4542c2b Move maffinity_base_alloc_policy and
maffinity_base_bind_failure_action MCA params to the hwloc base
(hwloc_base_alloc_polocy and hwloc_base_bind_failure_action).  Since
these MCA parameters were never on a release branch, I'm just
moving/renaming them outright and not leaving aliases to the old
names.

Note that some upper layer needs to call
opal_hwloc_base_set_process_membind_policy() to set the
set-by-MCA-param process-wide memory affinity policy.  We can't do
this automatically during hwloc_base_open() because, for reasons
described elsewhere, opal_hwloc_topology is not automatically filled
during hwloc_base_open() (in short: potential scalability issues when
launching many MPI processes simultaneously on a single machine, for
example).

This commit was SVN r25156.

[invalid policy]
WARNING: An invalid value was given for the
hwloc_base_general_alloc_policy MCA parameter. This MCA parameter
determines the policy used for general memory allocations. Note that
this parameter *only* has effect when MPI processes are bound to
specific processors.
The value provided was:
Local host: %s
PID: %d
Value: %s
Valid values are:
none: no memory binding policy is enforced
local_only: fail an allocation if it cannot be placed entirely on
the local NUMA node
Your job will now abort.
#
[mbind failure]
Open MPI failed to bind internal memory to a specific NUMA node. This
message will only be reported at most once per process.
Local host: %s
PID: %d
