Parallel rebuild

Threadpoolized parts of the rebuild process, fixed some minor issues in between as well.

added 1 commit

• 8c7d70a9 - don't assume the split flag is set correctly.

Compare with previous version

Ok, all fixed.

That all passes my tests now.

I will check whether it speeds up the big run.

@pdraper is there anything you want to cross-check here?

@nnrw56 that last merge requests (seemed more minor so looked first!) has broken this. Please merge in the latest master...

Let't me do that.

added 11 commits

• 8c7d70a9...ae0d4d25 - 10 commits from branch master
• 0ec2d1b4 - Merge branch 'master' into parallel_rebuild

Compare with previous version

Ok, that's fixed.

Hmm, not quite. I don't see the changes from engine.c in the new engine_maketasks.c. For instance all the cell_ensure_tagged() changes.
