array of stringified infos

[ompiteam]

As discussed a while ago, I think we should add something like this to the end of the hwloc_obj structure:

char infos; /< \brief Array of string name=value /
unsigned infos_count; /*< \brief Length of the infos array */

We would store in there things like:

DMIBoardVendor=Tyan (currently in obj->attr->machine.dmi_board_vendor)
DMIBoardModel=S4885 (currently in obj->attr->machine.dmi_board_info)
PCIVendor=AMD
PCIModel=Radeon HD4350

Some of them are already used in obj->name but that doesn't need to change.

Some system-fields might be interesting too, they should go in the topology or in the widest related object:

Backend=Synthetic
OS=Linux
LinuxCpuset=/foobar
FsRoot=/var/lib/topology/myworderfulmachine
Hostname=foobar

(In [2132]) Add an array of string infos in objects.

Print them in hwloc_obj_attr_snprintf.

Export them as a new element in XML files.

Refs #31.

Distinguish between object-specific and topology-wide infos.

Maybe it would be easier to store it as an array of structures containing the name and the property separately, instead of having to parse the '=' sign all the time.

Also, I guess it'd be good to provide a helper to look for some information, so the application programmer can just e.g. vendor = hwloc_object_get_info(object, "DMIBoardVendor").

Done. And indeed, it's better now.

Fixed in trunk [2320] when merging the objinfos branch (and applied to the libpci branch as well in [2323]).
