v3: fix checkpatch.pl errors and warnings.
v2: rebase to Matias' ordered queue impl, fix clang compilation.
This patchset provides an alternate scheduler which can be enabled
with --enable-schedule-iquery configuration option.
Run l2fwd and odp_scheduling performance test programs show equivalent
performance with the improved default scheduler, and can benifit use
cases of fewer queue count such as microservices, etc.
Supported parallel, atomic and ordered queue, with pktio polling.
ordered queue re-uses the algorithm in default scheduler.
pktio polling re-uses the same algorithm in default scheduler.
