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.

Misc objects were used between system and machine in the past
but quickly got replaced with groups.

Misc are reserved for annotating the topology, the core
doesn't like merging them. Group is more appropriate.

hwloc_get_first_largest_obj_inside_cpuset() returns the largest/highest object,
but it could still have a child with the same cpuset.
So check children as well in case there's a matching NUMA node there.

When ignore_keep_structure is enabled, intermediate level can disappear
between parent and child, making the new child complete_cpuset smaller,
causing the child list to require a reorder just like in remove_ignored().

If object A contains B + I/O as children, we can "ignore" I/Os and still
try to merge A and B. We now do the same for Misc objects without cpusets
instead of I/Os.
This fixes a corner case when export/reimport to XML creates a slightly
different topology (making hwloc_insert_misc fail inside a Linux cgroup).
Thanks to Dave Love for reporting the problem.

When I/O are attached under a PU, removing the children's cpusets from
the parent cpuset doesn't give 0, it gives the PU cpuset.
The assertion fails on single-pu machines with I/O when --merge is given,
only one PU remains with I/O under it.
But if we insert Misc by cpuset under PU, it gives 0 as expected.
Fix the assertion accordingly.

hwloc_x86_discover() calls hwloc_look_x86() twice, which calls hwloc_have_x86_cpuid().
If everything gets inlined, the asm label inside hwloc_have_x86_cpuid()
is duplicated.
Use a local label with f annotation in jumps to avoid the problem.

This commit adds an owner file in each of the component directories
for each framework. This allows for a simple script to parse
the contents of the files and generate, among other things, tables
to be used on the project's wiki page. Currently there are two
"fields" in the file, an owner and a status. A tool to parse
the files and generate tables for the wiki page will be added
in a subsequent commit.
As pointed out by @ggouaillardet, we were adding some unnecessary -I
flags to CPPFLAFGS when --without-hwloc was being used. This commit
slightly updates the hwloc191 component configury to only add such
things when the component is, in fact, going to be
compiled/installed.
