  1. openbsd: available_parallelism: use the right API 

    use the standard sysconf(_SC_NPROCESSORS_ONLN) way to get the number of 
available processors (capable of running processes), and fallback to 
sysctl([CTL_HW, HW_NCPU]) (number of CPUs configured) only on error.

it permits to differenciate CPUs online vs CPUs configured (and not necessary 
capable of running processes).

while here, use the common code path for BSDs for doing that, and avoid code 
duplication.

Problem initially reported to me by Jiri Navratil.
