indexes=8*2:4*2 specifies that we nest 2 interleaving loops: one loop with 2 steps with 8 between each, then one loop with 2 steps with 4 between each. PU#0 and open-mpi#1 will be 8 PU away, and PU#0 and open-mpi#2 will be 4 PU away.

On a 4-core machine with #2 offline, we want x86 to look at all 4 cores, so that we get info for all online ones (#1, #3 and #4). Before this commit, x86 would only look at the 3 first ones (just like if the offline PUs were always at the end of the range). At least Linux and Solaris can put some CPUs offline in the middle of the index range. So ask hwloc_fallback_nbprocessors() to get the number of existing CPUs.

rename topo_* into hwloc_*, libtopology into libhwloc, etc.
