On 32-bit architectures loads/stores of fast box headers may take
multiple instructions. This can lead to a data race between the
sender/receiver when reading/writing the sequence number. This can
lead to a situation where the receiver could process incomplete
data. To fix the issue this commit re-orders the fast box header to
put the sequence number and the tag in the same 32-bits to ensure they
are always loaded/stored together.
Fixes#473

fi_av_insert() is invoked with a context containing each endpoint
USNIC_NUM_CHANNELS times. If the address on that endpoint fails to
resolve / is unreachable / has some error, we'll therefore get
USNIC_NUM_CHANNELS error completions with that same endpoint. We
therefore only want to warn about the unreachability of (and
OBJ_RELEASE) that endpoint the *first* time.
Fixes CSCut46822.
This commit adds support for project_framework_component_* parameter
matching. This is the first step in allowing the same framework name
in multiple projects. This change also bumps the MCA component version
to 2.1.0.
All master frameworks have been updated to use the new component
versioning macro. An mca.h has been added to each project to add a
project specific versioning macro of the form
PROJECT_MCA_VERSION_2_1_0.

It was setup in the PCI backend before filtering,
and partially updated after filtering in the core.
Only setup once correctly after filtering in the core.

If super_set contains more allocated ulongs than sub_set,
we did not check the last ulongs.
We would return true instead of false when sub_set is
infinite while the last ulongs in super_set are not full.
This fixes tests/hwloc_bitmap_compare_inclusion on some platforms.

Otherwise we get spurious bits for crazy topologies such as 8em64t-2s2ca2c-buggynuma.output
Will make debug asserts easier.

Make sure we define complete cpuset/nodeset when we define groups' main cpuset/nodeset
during later insert of groups (for PCI hostbridges or distances).
Otherwise they may end up clearing child/parent complete sets which
suddenly become incoherent while they were fixed earlier.
Needed to fix allowed_nodeset meaning.

When looking for PUs inside R_MAXSDL rads, some AIX 6.1 releases
return one first rad without any PU.
AIX 6.1 00F63F144C00 does (on quad-power7).
AIX 6.1 00CBAAC24C00 doesn't (on 16x power6).
So we can't assume rad #x contains PU #x. But we already have the right
code to fill the cpuset from the rad, so use that to obtain the PU os_index
as well.
Cannot be used to obtain NUMA node os_index since there's no way to directly
retrieve NUMA nodes from rads (mempools seem unrelated). Just keep using #rad
for NUMA nodes os_index and document that convention when converting back in
set_membind().
Thanks to Hendryk Bockelmann and Erik Schnetter for helping debugging.

Otherwise we'll have some NULL objects above, would be annoying.
No need to dig further, the distance matrix is likely buggy.
We still keep the inserted groups at this level (incomplete level)
because removing them is hard.

Commit 626129d2818693e62b83c1cfa2ba6e058e5bed66 fixed the hwloc
device/vendor numbers obtained from libpciaccess.
But the corresponding names are still retrieved from pciaccess numbers,
so fix these numbers inside pciaccess structures before retrieving the names.
