repoman: Add --jobs and --load-average options (bug 448462)
Add --jobs and --load-average options which allow dependency checks
for multiple profiles to run in parallel. The increase in performance
is non-linear for the number of jobs, but it can be worthwhile
(I measured a 35% decrease in time when running 'repoman -j8 full'
on sys-apps/portage). For the -j1 case (default), all dependency
checks run in the main process as usual, so there is no significant
performance penalty for the default case.
